These low range models are available in capacities from 10 ozf-in to 200 ozf-in with overload ratings of 4X full scale. When installed between a driver and load, the sensor will measure static and dynamic shaft torque and speed (optional). A strain gaged titanium 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.
These models incorporate new technology that hardens them to EMI generated by IGBT based adjustable speed drives. High stiffness to inertia ratios makes these sensors ideal for stepper motor and other dynamic applications. Maximum speed rating is 25,000 rpm. A dual track 512 PPR encoder is optional as is a line driver for its output(s).
These models require strain gage, AC carrier style amplifier capable of providing 3 - 6 volts rms at 3 kHz ±10%.
