Model 1815 Series Enhanced Accuracy Rotary Torque Sensor, 50 lb-in to 10,000 lb-in, 0.05 % Non-linearity and Hysteresis, Spline Drive/Flange Mount, Extended Speed Range, up to 25,000 RPM. A line of enhanced accuracy rotary transformer torque sensors often ideal for test installations running long-term durability testing. Non-contact nature of the signal transfer virtually eliminates the need for maintenance. High overload protection with high signal output helps prevent potential damage to the sensor. Carrier frequency excitation provides increased signal/noise immunity. Optional Speed sensors available. Splines and flange mounting per AND 20002 and 10262.
