The T250-series rotary transformer coupled torque sensor was designed for in-line testing of propellers, pumps, drivelines, and other devices where there is minimal axial space available for the torque sensor. The T250 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 T250 housing. Interconnecting cable assemblies are available as an option. SensorData will provide in-house calibration of the T250 with customer-supplied electronics for a fee.
