Other applications include automotive, gear detection, machined part inspection, and machine tool positioning.

Working Principle

2LP18SP is a displacement sensor based on eddy current measurement principle. The eddy current measurement principle is based on the implementation of eddy current displacement. It can measure the displacement of metal objects by measuring the effect of the eddy current generated by the displacement of metal objects on the detecting coil. When the metal object moves parallel to the sensor face, it induces an eddy current in the component that is opposite in phase. The eddy current produces a magnetic field around the conducting coil, which excites its inductance

The inductance of the detecting coil of the eddy current sensor is proportional to the motor displacement relative to the sensor coil, and proportional to the product of the constant frequency and the current in the secondary detection coil. The output of the eddy current displacement sensor is a linear current signal proportional to the displacement of the measured metal object. The device uses a linear detection circuit, which can form a linear relation between the input signal and the output signal, that is, the output signal is linearly proportional to the displacement of the metal object.

In summary, 2LP18SP eddy current displacement sensor is a kind of small size, high sensitivity, strong anti-magnetic interference, long service life and repeatable measurement accuracy. It can be widely used in industrial control and automation, aerospace, automotive, automotive parts, transportation, environmental protection, metering and various high-tech fields.
