Slip-ring type Wheel Torque Measurement LTW-NA　2.5kN・m

This is a torque transducer for measuring driving torque and braking torque while an automobile is traveling. Torque can be measured with analog output by connecting the slip-ring and dynamic strainmeter that come standard. The slip-ring has a built-in encoder, allowing an F/V converter to be connected for counting output pulse and thereby measure rotational velocity. Preparing a special rim and hub adapter also allows the torque transducer to be installed to any passenger automobile.
