The LXT 970 torque transducer operates on the principle of magnetoelasticity. The sensors output signal is caused by a change in the magnetic field created by an applied torque on the sensor’s shaft. Non-contact detectors, in close proximity to the shaft, detect changes in the magnetic field and provide an electrical signal proportional to the torque. The electronics in the sensor provide signal conditioning suitable for use in industrial and process applications. The zero output is 2.5v. The output span can range from lOmv/v to 2.5v in either direction.
