Bearingless Digital Torquemeters Install Without Critical Constraints


S. Himmelstein and Company introduces the MCRT® 86000V and 87000V Series Bearingless Digital Torquemeters which offer exceptional installation latitude.  They tolerate rotor to stator misalignments of 1 inch axially and 0.3 inches radially.  Additionally, their antennae are immune to metal components positioned as close as one-tenth of an inch.

These new Torquemeters offer 0.05% accuracies, mechanical overload ratings of 400%, and 300% electrical overrange.  Such characteristics eliminate the need to compromise accuracy for safety when instrumenting diesel or other drives with high peak to average torque ratios.

Full scale ranges from 50 N-m to 10,000 N-m are available. An NIST traceable calibration performed in S. Himmelstein’s NVLAP accredited lab (Lab Code 200487-0) is supplied with each unit.  Analog, frequency and digital outputs are standard.    These models have exceptional immunity to EMI noise, ISM emitters, and closely spaced similar Torquemeters.  They are rated for use with variable frequency drives.
