RT 200 Series Reaction Torque Sensor

 
SpecificationsData Sheet

With its compact and maintenance-free design, the RT 200
Reaction Torque Sensor from Magtrol brings many signicicant
advantages to torque measurement applications. Based on
strain-gauge technology, the RT 200 Reaction Torque Sensor
provides highly accurate torque measurement. The RT 200
Reaction Torque Sensor has been designed to perform high
precision static torque measurement with small dynamic rotation
(and limited angle) in both the clockwise and counterclockwise
directions. The sensor measures small-reaction torque values
using shaft connections in-line with the component under test.
Main field applications include actuator and valve testing, and
fastener testing on medical devices.
