The inductive probe is often used in daily production. The performance of the inductive probe is relatively high, and the accuracy and stability are quite good, and the advantages are more prominent. It can be used with a dedicated measurement display gauge or with a PLC with high-speed counting function. It can be used to measure the radial error, axial swing, height difference, diameter, flatness, etc. of objects. But what is the measurement principle of the inductive probe? The following is a specific introduction to its use principle, I hope it will be helpful to everyone (Xingyujia Technology).

?? All types of inductive probes are used to carry out mechanical contact with the workpiece, the change in displacement is converted into a change in inductance. The mutual inductance coil fixed on the body of the probe induces the AC output voltage with the change of the position of the magnetic core inside. At the corresponding place, that is, the zero position, the voltage output is zero. The change in the measured place is transmitted to the magnetic core through the measuring rod, thus causing the inductance to change. After this change signal is amplified and shaped, it can be displayed in analog on a voltmeter according to the type of instrument or digitally displayed immediately through A/D conversion.

?? The acquisition of analog quantity is strictly required to be converted into a signal (display value) according to the measured variable (the place of the measuring rod); one of the outstanding advantages is that when the power is turned off (off or power off) and then restored, the prior The display will not be lost (Xingyujia Technology).

?? Through the above introduction, I believe that everyone knows the principle of inductance head measurement. For the place and place of its application, it is required to be very cautious. Whether it is the operation of robots, shaft diameters or glass, online detection can be used. In the process of use, it is necessary to work in strict accordance with the measurement principle and method of the inductor side head, so as to detect accurate data, and pay attention to the maintenance of the inductor side head, so as to prolong the service life of the device.
