INTERFACE MODEL T11 BEARINGLESS TORQUE TRANSDUCER.

The Interface Model T11 Bearingless Torque Transducer has a unique design that eliminates friction for precise low-torque measurement and is an excellent choice for high speed applications up to 30,000 rpm.

Available in capacities from 0.005 Nm to 150 Nm (0.04 to 1327 lbf-in), the T11 features ±5V output, 16-bit resolution and ±0.1% combined error. The T11 shaft spins freely within the stator with an air-gap separating the rotating shaft and stationary housing.

Applications include motor and bearing friction tests. The T11 can also be used for high-precision low torque measurement. The T11 ships with installed alignment plates to position the shaft within the housing. Available options include ±10V output, 6 pulse/rev +5V TTL speed
