Rotating Torque Sensors with Strain Gage Technology

for Motion Control Applications

We offer a complete range of torque transducers for incorporation into torque testing or monitoring assemblies; as well as complete measurement systems using state of the art mechanical and electronic technology. 

Our Torque Sensors offer high-precision measurement of torque and speed or rotation angle on rotating or stationary drive elements. Integral digital transmission techniques with normalized signal outputs allow optimal signal conditioning. Piezoelectric reaction torque sensors are suitable for measuring minute fluctuations in torque with a high degree of overload resistance
