MCRT 48850/51V series digital torque sensors from S. Himmelstein and Company offer extreme measurement accuracy and fast installed response. Output signals for torque, speed and horsepower are provided as analog (±5 or ±10 V DC) and digital over RS232/422/485 serial port in units with available capacities from 50 lbf-in to 10,000 lbf-in (5.65 N-m to 1,130 N-m).

Spline and flange configuration matches AND 10262 and 20002. Ceramic hybrid bearings and high speed grease are standard features. The sensors provide very high speed operation up to 30,000 rpm without the Source: S. Himmelstein and Companycomplexities of air-oil mist lubrication. The MCRT 48850/51V is compatible with Corrosive Red Oil and Skydrol.

Accuracy grades of ±0.05% and ±0.03% of full scale combined non-linearity and hysteresis are available. Mechanical overloads of 300% offer a safety margin in the presence of high startup torques or large torsional oscillations. Electrical overrange of 150% avoids clipping of real world torque peaks and driveline torsionals, reducing potential for errors in the average torque measurement. Output bandwidth is 1 kHz with 13 user selectable low pass filters.

Included interface software allows fast PC setup and re-configuration while selecting from up to 33 units of measure, all without recalibrating. All are calibrated CW and CCW to rated load in the ISO 17025:2017, NVLAP accredited laboratory (NVLAP lab code 200487-0).

These units are well suited for a broad range of applications including both performance and endurance testing of small pumps, motors, servo motors, gearboxes and actuators.
