1SBP260020R1001 Eddy current sensor, also known as eddy current sensor, is a non-contact linear measurement tool. It works based on the principle of electromagnetic induction and can statically and dynamically measure the distance between the measured metal conductor and the probe surface with non-contact, high linearity and high resolution. Specifically, when an alternating current passes through a metal coil, an alternating magnetic field will be generated; and when the metal is in an alternating magnetic field, an electric current will be generated in the metal body. This electric current is self-closing in the metal body, and It exhibits a vortex shape, so it is called eddy current. The size of the eddy current is related to parameters such as the geometric size of the metal conductor, material properties, coil excitation current frequency, and the distance between the coil and the surface of the metal body. Eddy current sensors are widely used, especially in many fields such as machinery, electric power, and petrochemical industry. It can be used to measure parameters such as shaft displacement, shaft vibration, and shaft speed of large rotating machinery, thereby analyzing the working conditions and fault causes of the equipment, and achieving protection and pre-maintenance of the equipment. Eddy current sensors have the advantages of long-term working reliability, high sensitivity, strong anti-interference ability, non-contact measurement, fast response speed, and are not affected by media such as oil and water. Overall, the 1SBP260020R1001 eddy current sensor is an efficient and accurate non-contact measurement tool that provides important technical support for equipment monitoring and maintenance in modern industrial fields.
