Shaft Driven Transformer Coupled Torque Sensor Model T261

  • Non-Contact measurement of torque
  • High stiffness and low inertia
  • On-board shunt calibration circuit
  • Internal zero velocity speed sensor
  • (optional) i200 AC carrier electronics (optional)
  • SAE 4340 alloy steel construction with satin nickel finish


The T261 rotary transformer coupled torque sensor was designed for in-line testing of motors, engines, transmissions, propellers, pumps, drivelines, and similar rotating devices. The T261 has greater stiffness, less rotating inertia, and smaller size than comparable models available from other suppliers. The T261 requires the use of AC carrier strain gage signal conditioning electronics such as SensorData’s i200. The optional zero velocity speed sensor is installed inside the T261 housing. Interconnecting cable assemblies are available as an option. SensorData will provide in-house calibration of the T261 with customersupplied electronics for a fee.
