Rotary torque sensor 421

with square connectionwith TEDS

The rotating torque transducers of the model series TesT 421 with standard square connection are the most common sensors for dynamic torque measurements. 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 and the industrial amplifier TesT 854 are 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 Measuring uncertainty - ≤ ± 0.1% of nominal value • Rotating • Torque • Electric
