February 6, 2019 - S. Himmelstein and Company, a manufacturer of torque sensors, torque transducers, and torque meters, recently introduced the MCRT 79800V Dual Range Digital Torque Transducers and the MCRT 48800V/49800V Digital Torque Sensors.
The MCRT 79800V Dual Range Digital Torque Transducers measure running and load torques. Both high range and low range outputs are always present. Output signals are provided as analog and digital simultaneously. A range of capacities are available from 40 lbf-in to 375,000 lbf-in. Accuracy grades are ±0.03% on the high range and ±0.05% on the low range of full scale combined non-linearity and hysteresis. Mechanical overload of 1,000% (low range) and 200% (high range) offers 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. They output ±10 Volt or ±5 Volt analogs of torque, speed (an option) as well as engineering unit data via a resident RS232/422/485 com port. Operation is fully bidirectional and measurements are valid to zero speed. In addition, the MCRT 79800V will measure normal torques when large transients are present.
The MCRT 48800V/49800V Series MCRT 48800V and 49800V Series Digital Torque Transducers are designed for measurement accuracy and high mechanical overloads and electrical overrange. Output signals for torque, speed and horsepower are provided as analog (±5 or ±10 Vdc) and digital over RS232 serial port. Available capacities are from 2.8 to 42,000 Nm. They are available in two accuracy grades: ±0.04% and ±0.02% of full scale combined non-linearity and hysteresis, and have world class temperature performance. Mechanical overloads of 200% or 400% offers a safety margin in the presence of high startup torques or large torsional oscillations such as produced by Diesel engines. 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.
They are suited for a range of applications including both performance and endurance testing of engines, transmissions, drive systems, pumps, motors, servo motors, gearboxes, actuators, etc.
