Displacement Sensor(eddy current sensor)

CWY-DO-Series proximity displacement transducer (eddy), based on the principle of the eddy current effect on the metal surface, tests and controls such mechanical quantity as displacement, vibration and rotating speed of the metal objects. Advanced properties of proximity test, wide linearity range, high sensitivity, strong ability of anti-disturbance, without medium influence, good stability and reliability and easy processing. It has been widely used in metallurgy, chemicals and astronautics and also the detection of such mechanical quantity as displacement, vibration, rotating speed, length, thickness and surface roughness of scientific research and experiments of the schools. Besides the test of static displacement, it has been widely applied in the measurement of vibration, axial displacement and rotating speed of such

rotating shafts as steam turbine, compressor and motor; and also applied in the application monitoring and fault diagnosis.
