The eddy current sensor WT0120-A00-B00-C05-D50 is a high-performance non-contact linearized sensing system designed to accurately measure the static and dynamic distance between the probe and the measured object. This sensor has a wide range of applications and is usually used to detect objects such as ferrite being measured. During the measurement process, the alternating electromagnetic field generated by the probe will be absorbed by the ferrite, and then sensed and processed in the electronic circuit of the sensor to accurately obtain the displacement of the measured object.

The eddy current sensor WT0120-A00-B00-C05-D50 has multiple significant advantages, including good long-term reliability, wide measurement range, high sensitivity, high resolution, fast response speed, strong anti-interference ability, and no influence from media such as oil pollution. These characteristics make it an ideal choice in industries such as power, machinery, chemical, and textile, especially for non-contact displacement measurement of large rotating machinery such as steam turbines, water turbines, blowers, compressors, gearboxes, and large cooling pumps.

Sensors have a wide range of applications, and can be used for measuring radial and axial displacement, differential expansion, shaft eccentricity, shaft vibration, keyphase, and rotational speed of shafts. Due to its non-contact measurement characteristics, eddy current sensors can maintain stable and reliable working performance even in harsh environments, making them very suitable for industrial applications with high precision requirements.
