Industrial Electronetics Corporation takes pride in announcing ultra reliable, rugged, miniature and low cost measurement
and telemetry systems now in production. These equipments designed and manufactured by engineers with over fifteen
years of experience in Government Missile systems, are simplified, accurate and advanced versions of the military equip-
ment but designed for industrial applications in measurement, control, and data analysis. Industrial operation and tests
heretofore impossible or made with great difficulty and dubious accuracy, may now be made reliably and practically-re-
sults being presented in directly meaningful numbers and graphs.
Typical applications have been:
1. Internal strain measurements of rotating equipment, chains, vehicles, and projectiles-eliminating slip rings and wires.
2. Measurements of vibration, acceleration, strain, temperature, pressure, magnetic fields, electrical current and voltage,
some to destructive proportions, may be made under difficult conditions such as at high electrical potentials, in fluids,
steam, or high velocity gases.
3. Measurement under actual operating conditions of vehicles and machinery without restricting their movements or other-
wise disturbing their normal functions.
4. Analysis of data to: determine resonant frequencies, make strain-weighted fatigue-life predictions, determine stress con-
centrations, locate operating hot spots, and determine power losses.
5. Control and feed-back links in automatic control systems for performing functions such as: laying of submarine cable,
ice detection and melting, operation of protective circuit breakers, and over temperature control of electric motors.
Many models of measurement, control, telemetry, and analysis equipment are available from stock for immediate delivery.
Custom modifications are supplied in 30 to 60 days and special purpose equipment is usually supplied within 00 days.
Your inquiries are invited and special configurations of our telemetry products or simplified low cost instrumentation of
almost any nature will be quoted upon request.

WHAT IS TELEMETRY
Radio Telemetry provides a method for transmitting data
by radio and presents a do voltage output to a readout equip-
ment or recorder. Radio telemetry may be most advantage-
ously employed where wired connections are impossible, un-
safe or technically undesirable.
I. E. C. Telemetry Systems are FM/FM. That is, both the
bridge exciting carrier and radio carrier are frequency modu-
lated. Frequency modulation provides better noise rejection
and greater freedom from interference under adverse en-
vironments than amplitude modulation.
Radio Telemetry is a novel tool to industry for scientific
measurements. Its range of application is limited only by the
user's imagination. Some suggested application areas are:
Rotating Machinery - Slipringless Data Acquisition
Distant Logging Center Data Transmission
Patient Monitoring in Physiological Studies
Kiln Temperature Measurements
TRANS-
DUCER
Transmission Lines
Troublesome Wire Links
Vehicular or Sled Tests
Railroad Equipment Studies
Hazardous Locations
Radio Telemetry has been developed by and primarily em-
ployed in government associated programs. Industrial ap-
plications have been retarded and restricted by technological
inadequacies and financial considerations. I. E. C. aims to
meet the requirements of industry-ACCURATE MEASURE-
MENT AT LOW COST.
A telemetry system consists of a completely transistorized
transmitting station and a receiving station. Transmitters
are potted in Epoxy Resin to provide rugged construction for
environmental extremes. Standard systems utilize the 88
me-108 me band. However, special systems are available
for operation in any band from 66 me-110 mc.

Units which are constructed using transistors, diodes,
tunnel diodes, varicaps and other low voltage solid state devices
should not be tested with instruments which apply test voltages
such as direct reading ohmeters, bridges, meggers, etc.,
or the units may be permanently damaged.
Signal generators with high AC output voltage and direct
coupled connections should also not be used.
The discharge of static electricity by high voltage
sparking from persons or moving objects such as belts, chains,
etc., should not be allowed to contact solid state devices or
permanent damage may result.
All encapsulated INDUSTRIAL ELECTRONICS CORPORATION
units contain transistors or other parts which may be damaged by
any of the above described applications of voltage.

General
The voltage controlled transmitter operates in the 88 to 108 mcs band. The
unit has seven solder connecting pins to which all external connections must be firmly
soldered. It may be exposed to temperatures from -40?C to +125?C during its normal
operation; it may be immersed in common lubricating oils; and it may be subjected to
shocks and continuous acceleration as great as 100 g without an external case. If
greater shock or acceleration is desired, it should be contained in a firm steel case
to support it on either of its flat sides during the high acceleration periods. Con-
nections to the transmitter are made for input signals, batteries and antennas. Proper
connections are clearly labeled on the accompanying drawing. There are two adjustments
on the transmitter. The larger screw adjustment is for changing the radio frequency.
The smaller adjustment is for zero offset provisions on the input voltage. In both
cases as the screw is rotated clockwise the frequency of the carrier or the subcarrier
respectively is increased. There are no limits which may damage either of these
adjustments. The radio frequency slug travels completely through the transmitter and
the offset adjustment is a 25-turn potentiometer which has a slipping clutch to prevent
damage at each end.
Input Connections
Three signal input connections are provided. If the input impedance of the
source is low, 10 ohms or less, it should be connected between ground pin #1 and input
pin #2. If a high impedance source is to be used, pin #2 should be solder connected
to ground pin #1 and the voltage applied from this junction to pin #3. Sources of
intermediate impedance may be used either (a) between pins #1 and #2 or (b) between
pin #3 and pin #2 by adding an appropriate shunt resistor in case (a) between pins
#2 and #3 or in case (b) adding the proper series resistor between pins #1 and #2.
Resistors should be chosen to bring the subcarrier to center frequency. Additional
subcarrier frequency adjustments may be made by means of the 25-turn potentiometer.
If a series resistance is used between the voltage source and pin #3 any magnitude of
voltage may be measured. Furthermore, the zero offset adjustment range may be varied
by connecting a resistor between pin #3 and pin #2 or pin #1 and pin #2.
Radio Frequency Considerations
The transmitter and its leads should be fixed securely to their mounting sur-
faces. Any motion between the transmitter and a closely spaced metal part will produce
frequency modulation of the self-excited oscillator. This does not disturb the data
until it becomes large enough to saturate the receiving discriminator. If motion be-
tween the transmitters, its leads and the mounting surface cannot be avoided then it
is desirable to place insulating material between these parts and the mounting surface.
Shielded leads to the input should be used whenever possible and the shield connected
to ground pin #1. If it is not possible to use shielded leads, the radio frequency
output may be coupled to the input circuit. If the intensity is great enough some of
the radio voltage will be rectified and provide a zero offset to the subcarrier. In
this case the offset adjustment should be changed after mounting of all the leads and
antennas is complete. Usually no antenna is required on the transmitter if the receiv-
ing antenna can be placed in proximity to the transmitter. If greater range is desired
short antennas (10" long) may be connected first to one pin, then the other, or both.
A short bit of experimentation is usually required to provide a satisfactory trans-
mitting antenna in cases where the transmitter is buried in metal engines, kilns, etc.
Antennas longer than 10" may change the transmitter frequency excessively, particularly
if they are mounted close to metal parts. Any length of wire may be used without damage
to the transmitter but care should be taken to mount it properly for satisfactory oper-
ation at the desired frequency. In the event the transmitter is to be operated in oil
or oil is al owed t splash on the transmitter the radio frequency tuning hole should
be filled atAPe%V jJfspr e"J5&9q0 9/91 f C~kbjiii}Q 1f0( QZ1QLQQit0(L 4draining from

Battery:
The transmitter is designed to operate at a voltage of 9 volts. Proper
operation may be obtained over the voltage range from 10 volts to 7.5 volts. An
internal regulator stabilizes the voltage to the transmitter when the battery voltage
varies. The regulator is an integral part of the temperature compensation system,
consequently, the best stability with change in temperature is obtained when oper-
ated at 9 volts. For most stable operation as large a battery as the application
permits should be used. Mercury cells and rechargeable nickel cadmium cells are
recommended for their voltage stability.
Battery leads should be as short as possible. If long leads are used,
shielded wire is recommended; the shield should be connected to the ground of the
transmitter. Battery voltage should always be measured under load, preferably at the
transmitter when the batteries are connected through the length of wire which will
be used.
Batteries should have a current rating of at least 10 ma. Under-rated
batteries or nearly discharged batteries may have a high internal impedance which
will cause parasitic oscillations of the transmitter. If multiple cells are connected
for a battery, all joints must be soldered. Pressure contacts will usually prove
unsatisfactory.
The proper polarity should be observed in connecting the battery to the
transmitter. If the battery is connected in reverse, excessive current will be
drawn and internal overheating will soon damage the transmitter.

The simplest, least expensive, and most versatile of telemetry systems -- a revolutionary.development in miniature oscil-
lators. The voltage output from a single active strain gage, battery excited, results in a modulated RF signal which is
received by .an FM receiver. The five channel unit pictured above is complete with rechargeable batteries.
A single 1.5 volt cell connected in series with a 60 ohm strain gage (gage factor 2) and a 390 ohm resistor produces a
voltage variation of 0.2 my from 500 millionths of an inch per inch strain which typically results in a 0.8 volt output of
the IEC receiving station.
Advantages: There is no need for bridge balancing or capacitance balancing. Transmitter power consumption. is

Stress Analysis
The STRAINTEL transmitter was created primarily as a design tool to render dynamic measurement of loaded structural
members. As such it is invaluable for final determinations of imposed loads, adequacy of designs, and analysis of situations
to be engineered.
The transmitter is useful in operating alarms at points distant from the monitor which are not easily linked by wire. In
this type of application, any number of transmitters properly tuned can be serviced at one point by a single receiving
station. A strain gage need not necessarily be a part of this system as any device impressing the required voltage at
the transmitter will create the necessary alarm at the receiver. This alarm may be acted upon automatically by instal-
lation of the desired auxiliary equipment. Installation of the proper transducers will permit the surveillance of pressure,
heat, temperature, mechanical movement, stress, strain, load, weight, acceleration, light, etc. In certain applications,
thermocouples produce sufficient electrical energy to operate the unit WITHOUT THE NEED OF BATTERIES!

Since the STRAINTEL does not include a subcarrier oscillator, the receiving station need not incorporate a discriminator.
Considerable savings result on system cost. The receiving stations utilize standard tuners modified to improve sensi-
tivity and linearity and, to reduce noise. They are mounted in standard IEC cabinets. As a result, a customer can
procure a STRAINTEL low cost system with the advantages of telemetry, and at a future date, incorporate a discriminator
for reception of data from transmitters utilizing a subcarrier oscillator.

WHAT IS TELEMETRY
Radio Telemetry provides a method for transmitting data
by radio and presents a dc voltage output to a readout equip-
ment or recorder. Radio telemetry may be most advantage-
ously employed where wired connections are impossible, un-
safe or technically undesirable.
I. E. C. Telemetry Systems are FM/FM. That is, both the
bridge exciting carrier and radio carrier are frequency modu-
lated. Frequency modulation provides better noise rejection
and greater freedom from interference under adverse en-
vironments than amplitude modulation.
Radio Telemetry is a novel tool to industry for scientific
measurements. Its range of application is limited only by the
user's imagination. Some suggested application areas are:
Rotating Machinery - Slipringless Data Acquisition
Distant Logging Center Data Transmission
Patient Monitoring in Physiological Studies
Kiln Temperature Measurements
TRANS-
DUCER
TRANS-
DUCER
Transmission Lines
Troublesome Wire Links
Vehicular or Sled Tests
Railroad Equipment Studies
Hazardous Locations
Radio Telemetry has been developed by and primarily em-
ployed in government associated programs. Industrial ap-
plications have been retarded and restricted by technological
inadequacies and financial considerations. I. E. C. aims to
meet the requirements of industry-ACCURATE MEASURE-
MENT AT LOW COST.
A telemetry system consists of a completely transistorized
transmitting station and a receiving station. Transmitters
are potted in Epoxy Resin to provide rugged construction for
environmental extremes. Standard systems utilize the 88
me-108 me band. However, special systems are available
for operation in any band from 66 me-110 me.

Units which are constructed using transistors, diodes,
tunnel diodes, varicaps and other low voltage solid state devices
should not be tested with instruments which apply test voltages
such as direct reading ohmeters, bridges, meggers, etc.,
or the units may be permanently damaged.
Signal generators with high AC output voltage and direct
coupled connections should also not be used.
The discharge of static electricity by high voltage
sparking from persons or moving objects such as belts, chains,
etc., should not be allowed to contact solid state devices or
permanent damage may result.

General
The voltage controlled transmitter operates in the 88 to 108 mcs band. The
unit has seven solder connecting pins to which all. external connections must be firmly
soldered. It may be exposed to temperatures from -40?C to +125?C during its normal
operation; it may be immersed in common lubricating oils; and it may be subjected to
shocks and continuous acceleration as great as 100 g without an external case. If
greater shock or acceleration is desired, it should be contained in a firm steel case
to support it on either of its flat sides during the high acceleration periods. Con-
nections to the transmitter are made for input signals, batteries and antennas. Proper
connections are clearly labeled on the accompanying drawing. There are two adjustments
on the transmitter. The larger screw adjustment is for changing the radio frequency.
The smaller adjustment is for zero offset provisions on the input voltage. In both
cases as the screw is rotated clockwise the frequency of the carrier or the subcarrier
respectively is increased. There are no limits which may damage either of these
adjustments. The radio frequency slug travels completely through the transmitter and
the offset adjustment is a 25-turn potentiometer which has a slipping clutch to prevent
damage at each end.
Input Connections
Three signal input connections are provided. If the input impedance of the
source is low, 10 ohms or less, it should be connected between ground pin #1 and input
pin #2. If a high impedance source is to be used, pin #2 should be solder connected
to ground pin #1 and the voltage applied from this junction to pin #3. Sources of
intermediate impedance may be used either (a) between pins #1 and #2 or (b) between
pin #3 and pin #2 by adding an appropriate shunt resistor in case (a) between pins
#2 and #3 or in case (b) adding the proper series resistor between pins #1 and #2.
Resistors should be chosen to bring the subcarrier to center frequency. Additional
subcarrier frequency adjustments may be made by means of the 25-turn potentiometer.
If a series resistance is used between the voltage source and pin #3 any magnitude of
voltage may be measured. Furthermore, the zero offset adjustment range may be varied
by connecting a resistor between pin #3 and pin #2 or pin #1 and pin #2.
Radio Frequency Considerations
The transmitter and its leads should be fixed securely to their mounting sur-
faces. Any motion between the transmitter and a closely spaced metal part will produce
frequency modulation of the self-excited oscillator. This does not disturb the data
until it becomes large enough to saturate the receiving discriminator. If motion be-
tween the transmitters, its leads and the mounting surface cannot be avoided then it
is desirable to place insulating material between these parts and the mounting surface.
Shielded leads to the input should be used whenever possible and the shield connected
to ground pin #1. If it is not possible to use shielded leads, the radio frequency
output may be coupled to the input circuit. If the intensity is great enough some of
the radio voltage will be rectified and provide a zero offset to the subcarrier. In
this case the offset adjustment should be changed after mounting of all the leads and
antennas is complete. Usually no.antenna is required on the transmitter if the receiv-
ing antenna can be placed in proximity to the transmitter. If greater range is desired
short antennas (10" long) may be connected first to one pin, then the other, or both.
A short bit of experimentation is usually required to provide a satisfactory trans-
mitting antenna in cases where the transmitter is buried in metal engines, kilns, etc.
Antennas longer than 10" may change the transmitter frequency excessively, particularly
if they are mounted close to metal parts. Any length of wire may be used without damage
to the transmitter but care should be taken to mount it properly for satisfactory oper-
ation at the desired frequency. In the event the transmitter is to be operated in oil
or oil is allowed to 1 on }emit the radio fre uency tuning hole should -sh be filled at tQv~i~d g ~t ~~ 'b'i31 9-h?79f% 11~0441M1091Q-4lraining from
the hole, thereby changing the radio frequency.

Battery
The transmitter is designed to operate at a voltage of 9 volts. Proper
operation may be?obtained over the voltage range from 10 volts to 7.5 volts. An
internal regulator stabilizes the voltage to the transmitter when the battery voltage
varies. The regulator is an integral part of the temperature compensation system,
consequently, the best stability with change in temperature is obtained when oper-
ated at 9 volts. For most stable operation as large a battery as the application
permits should be used. Mercury cells and rechargeable nickel cadmium cells are
recommended for their voltage stability.
Battery leads should be as short as possible. If long leads are used,
shielded wire is recommended; the shield should be connected to the ground of the
transmitter. Battery voltage should always be measured under load, preferably at the
transmitter when the batteries are connected through the length of wire which will
be used.
Batteries should have a current rating of at least 10 ma. Under-rated
batteries or nearly discharged batteries may have a high internal impedance which
will cause parasitic oscillations of the transmitter. If multiple cells are connected
for a battery, all joints must be soldered. Pressure contacts will usually prove
unsatisfactory.
The proper polarity should be observed in connecting the battery to the
transmitter. If the battery is connected in reverse, excessive current will be
drawn and internal overheating will soon damage the transmitter.
