Eddy current sensorInstruction Manual

I. Overview

The eddy current displacement sensor adopts micro patch packaging and circuit improvement technology, integrating the probe and preamplifier into one. Due to its non-contact measurement, good long-term reliability, high sensitivity, strong anti-interference ability, response speed block, and immunity to media such as oil and steam, it is often used for long-term real-time monitoring of axial displacement, swing, shaft vibration, speed and other parameters of large rotating machinery in industries such as power, steel, and petrochemicals.

3、 Installation instructions

★Requirement for the tested object: The influence of the tested object material on the sensor characteristics

=When the measured object is a circular axis and its axis is orthogonal to the axis of the probe, it is required that the diameter of the measured object be greater than the diameter of the probe3More than twice, otherwise the sensitivity of the sensor will decrease.

=The thickness of the measured object affects the sensitivity of the sensor. Metal materials with good magnetic conductivity such as steel require a thickness greater than0.1mmMetal materials with good magnetic conductivity such as aluminum require a thickness greater than0.6mm.

=The tested material is45#Steel, otherwise there will be errors.

=The measured surface should be smooth and free of holes, scratches, etc. For speed and phase detection measurements, convex platforms or grooves can be installed on the measured surface. Displacement measurements generally require that the surface roughness of the measured surface does not exceed0.8～1.6um,Shaft vibration measurement generally requires that the surface roughness of the measured surface should not exceed0.4～0.8um.

When placing an order, the user must specify the material, shape, size, etc. of the tested object. If the user does not specify in the contract, the factory inspection will be conducted45#Steel is used as the material of the tested object, and the diameter of the tested object's plane is greater than or equal to3Calibrate by multiplying the probe diameter.

Wiring requirements:

The on-site power supply and signal input must be grounded together, otherwise it may damage the sensor.
