The Model 10A45 has been specially designed to receive, condition, and process the
TORQUE, REFERENCE TORQUE, and THERMISTOR signals generated by a
Simmonds
Precision Model T6 Shaft Torque Sensor
operating from 30 to 32000 Hz.* Using a
phase displacement technique, this sensor has proven very successful in the accurate
measurement of shaft torque, speed, and temperature developed by jet and other high-
power engines—even in the presence of phase modulation produced by differential radi-
al displacement of the shaft assembly and of high torsional vibration caused by radial
runout, erratic loading, etc.
Connected to the Simmonds Shaft Torque Sensor via 6- or 8-wire shielded cable, the
10A45 provides three linearized “Subchannels,” with corresponding analog outputs to
wire-wrap pins:
• Subchannel No. 1
: SHAFT TORQUE
• Subchannel No. 2
: SHAFT SPEED in RPM
• Subchannel No. 3
: SHAFT TEMPERATURE—this data is necessary for accurate
compensation of the torsional modulus of the shaft material.
By application of a simple System 10
CALCULATE (CLC)
command on the torque and
RPM channels, horsepower indication is also easily obtained (see Section 3.b, below).

* Under special conditions, it may also be used with certain similar transducers. Contact the facto-
ry for more information.
** Initial (uncalibrated) inaccuracy may be as great as ±0.05% of full scale. Maximum error that
could occur upon replacement of a Model 10A45 not followed by calibration is ±0.1% of full
scale.
