Some common problems in the probe of coating thickness gauge
The probe of the coating thickness gauge may occasionally have some problems during use. When repairing the probe of the coating thickness gauge, it is often found that the magnetic core is severely worn, and some can be said to be severely damaged. For example, the gemstone core of N1 head is often damaged and chipped, and the arc core of F1 head magnetic core is flattened or deformed.
Firstly, it is normal for the probe to wear out during use. But if users pay attention to its characteristics, it will prolong its service life.
A common problem among them is that during measurement, due to the usual downward testing, users often use more force to push down, which can easily lead to the failure of the probe core over time. The correct way to use it is to gently press the probe towards the surface of the workpiece being measured when it is one centimeter away, because the probe is designed with an induction pressure spring built-in, which only needs to be lightly pressed. On the other hand, during the repeated movement of the probe, it is easy to collide, collide, and collide with other objects, which can also cause damage to the probe head. Therefore, if working conditions permit, the probe head can be fixed and the measured workpiece can be placed in contact with the probe, thereby reducing the collision of the probe.
There is also a situation where, when measuring, the measuring head must be lifted and not pulled flat to reduce the wear of the magnetic core.
Finally, the probe must be kept away from strong magnetic fields to avoid changing the natural frequency of the probe and causing it to malfunction. The correct operation and usage methods extend the service life of the instrument.
