The T351 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 slip ring allows the use of either AC carrier or DC strain gage signal conditioning electronics. The optional zero velocity speed sensor is installed inside the T351 housing. Interconnecting cable assemblies are available as an option. SensorData will provide in-house calibration of the T351 with customer-supplied electronics for a fee.
