Model 422

The rotating torque transducers of the model series TesT 422 with incremental angle measurement and standard square connection are typically used, when torque and angle are to be determined simultaneously. Between 1 Nm and 5000 Nm 12 graded transducers are available. The torque transducers are robust and suitable for industrial applications. The electronic indicator TesT 813 is used for analysis purposes. These torque transducers are also used as torque measuring devices in TesT Torsion Testing Machines for high-precision measurements, in combination with the USB controller TesT 850 and the software TesTWinner®.
