Dual-range digital torque meters

  • 13-Apr-2012 04:17 EDT


With a high range of 200 to 4,000,000 lbf-in (22.6 to 451,939 N·m) and a low range of 40 to 800,000 lbf-in (4.5 to 90,387 N·m), S. Himmelstein’s MCRT 88700V series dual-range torque meters accurately measure low-running and high-load torque without the cost and inconvenience of swapping two or more conventional torque sensors. The devices accurately measure torque even if the ratio of peak to average torque is high. Such conditions occur when starting, stopping, or reversing high inertia loads, during torsional oscillations, and in diesel and single-cylinder engine/compressor drivelines. Under these conditions, a conventional torque meter must be oversized to avoid damage, which, according to the company, is a process that greatly reduces accuracy.
