Low range bearingless digital torque sensors with high precision

05 January 2022

The MCRT 80001V series bearingless digital torquemeter from S. Himmelstein and Company offers a compact solution for making low torque measurements with high accuracy. Available capacities are 5 Nm, 10 Nm, 20 Nm and 50 Nm, and torque signal outputs include analog, digital and FM data. The torquemeters feature mechanical overload protection to 200% of full scale and also have the industry's highest electrical over-range at 150%.

The MCRT 80001V allows wide tolerance of rotor to stator alignment greatly easing installation and reducing the risk of contact resulting from thermal or mechanical growth. A Carrier amplifier, immune to Source: S. Himmelstein and CompanySource: S. Himmelstein and Company DC and low frequency noise, handles the torque bridge output. Hardening against electromagnetic interference (EMI) generated by variable frequency drives, industrial-scientific-medical radio frequency band transmitters and other industrial noise sources further enhances performance.

Features include:

• 0.02% combined nonlinearity and hysteresis

• Low sensitivity to clamping loads

• 0.00054%/° C compensation

• 10 units of measure

• 13 selectable bessel data filters

• 20 kHz max/min update

• 3 kHz measurement bandwidth

• Zero velocity speed pickup option

The MCRT 80001V provides exceptional ease of installation and operating efficiency. All units are shipped with an NIST traceable calibration performed in the company's ISO 17025:2017 accredited metrology laboratory (NVLAP Lab Code 200487).

Typical applications include, but are not limited to, performance characterization and efficiency testing of small electric motors, gear boxes, pumps and compressors.
