MCRT® 88700V High Capacity Dual Range Torquemeters measure high and low torques with high accuracy and without the cost and inconvenience of swapping two conventional sensors. They correctly measure torque if the peak to average ratio is high. Their use avoids the accuracy loss that occurs if an oversized sensor is used to prevent damage. Accuracy is high in real-world applications, not just in the cal lab.

That’s due, in part, to very high stiffness which yields wider installed bandwidth and faster response than competitive1 devices. Industries highest overrange avoids errors from clipped torque peaks. World class temperature performance reduces drive heating and gradient errors. Also enhancing real-world performance is noise hardening against EMI from VFDs, ISM transmitters and other noise sources. Each range is calibrated to full scale with 10 CW and CCW steps (20 total) and documented by a NVLAP approved Certificate certifying NIST traceability and that our laboratory operation and quality management system meet ISO/IEC 17025:2017.

A Bidirectional rotor shunt cal verifies calibration and operation of the entire data chain in CW and CCW modes. It is invoked via stator switches, I/O line or from your computer. Multiple bridges and elegant design provide exceptional immunity to clamping and other extraneous loads. The torque signal is digitized on the rotor and sent to the stator where analog, frequency and Com Port outputs are created. Choose RS232/RS422/RS485 or USB communications. Included software interfaces with your Windows-based PC. It displays Realtime, Max/Min and Spread Torque, Rotor Temperature, checks limits, does torque time plots and stores test results.
