MCRT® 86000V Torque Transducers output shaft torque with 0.01% resolution. Digital, Analog and FM formats are simultaneously available. Industries highest overload and overrange ratings assure safety and accuracy even when the driveline has high peak to average torque ratios. Important features include non-critical installation, temperature data, max/min capture and absence of manual adjustments.

Span Drift (% of Reading/deg. F.)



Temperature Ranges (deg. F.)

Compensated Range: +75 to +175; Usable Range: -25 to +185; Storage Range: -65 to +225

Rotor to Stator Maximum Misalignment (inches)

Axial: ±0.4, Radial: 0.3; If Speed Pickup Option is installed then maximums may be reduced - call factory.

Analog Output Signals6, Auto-Scaled

MCRT® 86000V Full Scale Torque3

Default is ±10V with 50% overrange (±15V). User may select ±5V with 50% overrange (±7.5V). Caution: see Note 7.

MCRT® 87000V Full Scale Torque3

Default is ±5V with 300% overrange (±15V). User may select ±10V with 50% overrange (±15V). Caution: see Note 7.

Signal Filter Cutoff Frequency4

Field selectable from 1 to 1 kHz in ten 1-2-5 steps plus 3 kHz selected from a remote PC using software furnished. Filters have Bessel Response; no delay distortion or overshoot errors.

Frequency Modulated Output, Auto-Scaled

Frequency: 10±5 kHz or 20±10 kHz or 40±20 kHz; field changeable (Default = 10±5 kHz); TTL square wave output.

Overrange (% of Range, see Application Note 20805)

50 to 300; model/user selection dependent - see above. Applies to analog, Digital and FM (except for negative side) Outputs.

System Resolution (% of Range)


Output Noise, All Outputs (% of Range)

<0.01 at 1Hz, <0.01 at 10 Hz, < 0.015 at 100 Hz, <0.028 at 1 kHz and <0.041 at 3 kHz.

System Response

Torque is sampled @ 20 kHz. Its’ 3 db bandwidth is 3 kHz but can be reduced by filters (see above)

Rotor-to-Stator Transfer Rate

1.25 MBaud

RS232, RS422, RS485 Communications Port

Com port outputs Torque and Temperature with units of measure. Inputs torque range if other than sensor full scale, selects units of measure, selects BAUD Rate, and permits remote computer control of the test.


9,600 to 230,400 (default is 115,200); Drivers are protected for short circuit (current limit) and ±15kV ESD protected

Maximum Cable Length

RS232 = 50 feet, RS422/485 = 4,000 feet; 120 Ohm termination may be accessed via software.

Interface Software

Provided to interface with Windows-based PC. Includes interconnect cable for a PC.

I/O Lines

5 input and 2 output, all are user assignable. Default for 5 inputs are +CAL, -CAL, TARE, CLEAR TARE, and RESET MAX/MIN.

Status LED’s (on Stator Keypad)

Three Color Coded LED’s: Power (Yellow = Power-up, Green = OK, Red = Fault); Data (Green = OK, Red = Data Error); Rotor Temperature (Green = In Operating Range, Red = Out of Operating Range).

Keypad Control Switches

+ CAL invokes CW Rotor Shunt Cal, -CAL invokes CCW Rotor Shunt Cal, Both held simultaneously for 5 seconds invokes TARE.

Rotor Temperature, Auxiliary Measurement

Rotor temperature is outpout via Comp Port. Range is 0 to 185 degrees F.; Accuracy is ±2 degrees. See above for status LED’s.

Option Code Z
