It has the advantages of small size, high reliability, and non-contact measurement, and is suitable for various turbomachinery. It can measure physical quantities such as shaft vibration and displacement. EPRO provides customers with various models of eddy current sensors that can meet various measurement schemes. The following physical quantities can be measured: - Clearance between the rotating and fixed parts - Vibration and eccentricity of the shaft - Radial and axial displacement of the crankshaft - Thickness of the wear oil film of the bearing shell - Relative thermal expansion of the shaft and bearing - Thermal expansion of the bearing - Valve] The manufacturing and use of position sensors comply with multiple common standards, such as API 670 DIN 45670 and ISO 10817-1. After installing safety barriers, sensors and proximitors can also operate in environments that require explosion protection, in accordance with relevant European standards EN 50014/50020. Displacement sensor Speed probe: The monitoring principle of eddy current sensors and velocity sensors is based on the principle of eddy current effect. The coil of the eddy current sensor is connected in parallel with a capacitor C, forming a parallel resonant circuit. Excited by a stable high-frequency current supplied by the product oscillator in the front end, a high-frequency alternating magnetic field is generated around the wire. When the measured spindle is close to the range of the secondary alternating magnetic field, an eddy current is generated on the surface of the measured spindle, which in turn generates a new alternating magnetic field to hinder the change of the main magnetic field. This process consumes energy and causes the Q value of the coil to change. When the gap d between the measured spindle and the sensor changes, the Q value of the sensor coil also changes accordingly.
