The T123 is designed to support the housing of motors, generators, pumps, and similar devices and accurately measure the non-rotating reaction torque values where the rotating member of the device under test is passed through the center of the sensor. The T123 with inherent low-end measurement capability can be installed at the driver or absorber end of the measurement chain. The flanges, pilot diameters and bolting studs of the T123 are configured to AND standards. AC carrier or DC strain gage signal conditioning electronics can be used with the T123. A removable calibration arm and interconnecting cable assemblies are available as options. In-house calibration of the T123 with SensorData electronics will be provided free of charge or with customer-supplied electronics for a fee.
