The T258 rotary transformer torque sensor with a spline drive and flanged housing meets the mounting requirements of Army-Navy standards AND 20002 and AND 10262. The T258 has been field proven in high speed aircraft fuel pump test stands and is rated to operate at speeds up to 35,000 RPM over extended periods with standard grease pack bearings. The T258 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 T258 housing. Interconnecting cable assemblies are available as an option. SensorData will provide in-house calibration of the T258 with customer-supplied electronics for a fee.
