General Info

The MCRT 79000V series was developed to accurately measure torque when the ratio of peak torque to average torque is high. In this situation, a conventional torquemeter must be oversized to avoid damage – a process which greatly reduces accuracy. Conditions that create high peak to average ratios include starting, stopping or reversing inertial loads, torsional oscillations, and diesel and single cylinder engine/compressor drives. Additionally, when peak torques are unknown, an MCRT 79000V reduces the risk of damage from unexpected or accidental torque spikes.

An MCRT 79000V can accurately measure low running torque and high transient spikes without the expense of using several conventional sensors. Furthermore, these products are hardened to the intense electromagnetic interference (EMI) often generated by modern, IGBT-based adjustable speed drives/controls.

These torquemeters use patented Himmelstein technology newly refined to achieve MCRT 79000V performance. Rotary transformers connect torque sensing strain gauges to stationary circuitry without contact. Transformers don’t generate noise or wear. They are immune to noise, dirt and lubricants and provide long, maintenance-free life. Unlike ferrite transformers, Himmelstein’s robust; non-ferrite design isn’t susceptible to cracking and impact damage. MCRT 79000V sensors are suitable for diesel service and other hostile environments.

RFI shielded circuitry, improved EMI tolerance, and the high level output with low source impedance further enhance noise immunity. Simple cabling yields calibration and balance truly free of cable effects. There are no slip rings, brushes, radio transmitters or other limited-life, noise-generating elements.
