System Overview
The TorqueTrak 9000 is a battery-powered digital radio telemetry
system designed to transmit a single millivolt data signal
(typically from a strain gage or gage-type sensor) 20 feet or
more. Up to 8 individual systems can be operated concurrently
on different frequencies to transmit multiple data signals.
The TorqueTrak 9000 consists of two primary components: the
BT9000 Bridge Transmitter and the RD9000 Receiver.
The TorqueTrak 9000 features:
fully encapsulated rotating electronics
user-selectable input range
user-selectable transmit/receive frequency
AutoZero switch (sets output to zero at no load)
RF signal strength indicator
low battery voltage indicator
switchable low pass filter
reverse polarity switch
excellent accuracy and stability
minimal drift with ambient temperature changes
microprocessor-based digital circuitry from sensor input to
signal output
Ideal for short term diagnostic testing, the TorqueTrak 9000 is
rugged, intelligent, and simple to use.

Features and Controls
RD9000 Receiver
RD9000 Front Panel Controls
Power
Switch
Power Light
On if unit is
powered.
AutoZero
Up position applies an offset to
correct the output to zero volts (set
zero volts out for no-load input). In
down position, no offset is applied.
Low TX Power
Blinking light indicates low
power at transmitter (e.g.
time to change battery).
Full Scale Adjust
Reduces amplitude of
output voltage (for
scaling).
Data Light
On solid indicates successful
data transmission. Blinking or
flickering light indicates data
errors.
Full Scale Switch
In up position, receiver generates positive
full scale voltage signal at Output (can be
attenuated with Full Scale Adjust). In down
position, receiver outputs live data signal
(from transmitter).
Display Output/RF Level Indicator
In the Display Output mode (switch up)
LEDs indicate relative output voltage from
-Full Scale to +Full Scale. In the RF Level
mode (switch down), LEDs indicate relative
RF signal strength.

Filter Switch
Switch to up position to
apply 10Hz low-pass filter
to voltage output.
Power Input Jack
Connect to 12VDC
(e.g. wall plug
transformer).
Voltage Output
Connect to chart recorder
or other read-out device.
(±10V Full Scale)
Polarity Switch
Switch to down position
to reverse polarity on
voltage output.
RF Channel Selector
Adjust receiver knob to match RF
transmit frequency of BT9000
transmitter.
Antenna
Connect to RA900
antenna using SMA-
SMA cable.

Set Up Procedure
Before installing the telemetry it is important to verify that the
gain setting of the transmitter is suitable for the expected sensor
load. (The BT9000 transmitter is factory set for a gain of 2000
(Gain Level = 4) which will accommodate most torque
applications.) To determine the appropriate gain setting for a
given application refer to the calculations in Appendix C.
Instructions for changing the transmitter gain setting are in
Appendix E. For instructions about changing the RF channel see
Appendix D.
1. Attach sensor or strain gage(s) to shaft or device being
measured. Be sure shaft and/or sensor is unstrained when
attaching as this is the zero load reference.
2. Secure transmitter and 9 volt battery to shaft or device being
measured using fiberglass strapping tape. Alternatively,
hose clamps, machined collars or other methods or devices
may be used but care should be taken to avoid excessive
compression on the transmitter and battery. CAUTION:
Make sure all components are securely fastened to rotating
equipment. Avoid injury by standing clear of attached items
which may come off during machine operation if improperly
secured!
3. Solder an appropriate length of 4-conductor ribbon cable or
suitable leads to gage or sensor. (Note: Keep ribbon cable
as short as practical (6-8 inches typical). Long cable runs
may pick up unwanted electrical noise.)
4. Connect other end of ribbon cable leads to appropriate
screw terminals on BT9000 transmitter. Secure battery
connector to appropriate screw terminals on BT9000, and
attach to 9 volt battery.

Transmitter, Battery and Sensor Connections
5. Using the provided 25ft coax antenna cable connect the
RA900 receiving antenna to Antenna connection on rear
panel of RD9000 receiver.
6. Position RA900 magnetic-mount receiving antenna near
transmitter, typically within 10 feet.
RD9000 Rear Panel
7. Connect 12VDC AC adapter (Model AC110 or AC220) or
other 12VDC supply to Power Input jack on RD9000 rear
panel. Plug adapter into appropriate power source (wall
outlet). Move RD9000 power switch to On.
