MCRT® 48000V Series DC Operated Torquemeters are available in capacities from 25 lbf-in to 4,000,000 lbf-in with overload ratings of 2X full scale. Integral signal conditioning provides dual ±5 volt dc outputs proportional to torque. They will operate from a single power supply in the range of 10.5 to 24 volts dc (such as 12 volt batteries)
When installed between a driver and load, the sensor will measure static and dynamic shaft torque and speed (optional). A strain gaged stainless steel shaft senses torque and cancels bending and thrust. Robust, ferrite free rotary transformers connect the gages to noise immune carrier amplifiers. They don't generate noise or wear, are immune to magnetic fields, noise, vibration, lubricants and other hostile environments.
They are available in either shaft or flanged style configurations. Shaft end torquemeters are less costly than flanged models and can be either floated or foot mounted. Flanged models are much shorter and can be used when axial space is limited or when the highest shaft stiffness is needed.
