T259

The T259 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 T259 is rated to operate at speeds up to 20,000 RPM over extended periods with standard grease pack bearings. The T259 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 T259 housing. Interconnecting cable assemblies are available as an option. SensorData will provide in-house calibration of the T259 with customer-supplied electronics for a fee.
