Dual Range Bearingless Digital Torque Sensors
Available from S Himmelstein and Company
Model MCRT® 88700V Series high capacity dual range torque sensors will accurately measure low running and high load torque without the cost and inconvenience of swapping two or more conventional torque sensors. Available high ranges from 300,000 to 4,000,000 lbf-in (33.9 to 452 kNm) and low ranges from 60,000 to 800,000 lbf-in (6.78 to 90.4 kNm). They are offered in two performance grades, standard ±0.1%, and enhanced ±0.05% combined non-linearity and hysteresis of each range full scale.
Important applications include measuring 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® 88700V reduces the risk of damage from unexpected or accidental torque spikes.
These Dual Range Torquemeters have high accuracy in real-world applications, not just in the cal lab. They have the industry’s highest Overrange ratings, which avoids clipping real-world torque peaks and driveline torsionsals. Without sufficient Overrange, clipped torques will produce large measurement errors.
