Common problems encountered in the use of coating thickness gauge probes
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 a normal phenomenon for the probe to be worn during use. But if users pay attention to its characteristics, it will extend 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 method of use is to gently press the probe towards the measured surface when it is one centimeter away from the measured workpiece, as the probe is designed with an induction pressure spring built-in, which only needs to be gently pressed down. On the other hand, during the repeated movement of the probe, it is easy to collide, collide, or collide with other objects, and also cause damage to the probe. Therefore, if working conditions permit, the probe can be fixed and the measured workpiece can be in contact with the probe, thereby reducing the collision of the probe.
There is also a situation where the measuring head must be lifted and not pulled flat when measuring a point 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. Correct operation and usage methods * * extend the service life of the instrument.
5 precautions for using coating thickness gauge
1. Do not use inferior batteries to avoid liquid leakage and corrosion of the host motherboard. Once any leakage is found, please send it for repair immediately. If it is too late, the host will be scrapped directly. If not used for a long time, please remove the battery.
When inserting or unplugging probes, the host power must be turned off before inserting or unplugging. Otherwise, it is easy to cause the integrated block inside the probe to burn out.
3. When measuring, the probe should be placed steadily, and the force should not be too large. It should not be measured at very fast points; During testing, the probe should not be scratched or scratched on the surface being tested, as this can easily cause damage to the probe.
4. It is very important not to measure when the coating is not dry. Many customers often measure when the coating is not dry. After the probe is coated with paint, it is cleaned with banana water or xylene before use. If operated in this way, the most serious probe will be directly scrapped. Even if it is not scrapped, the sensitivity of the probe will be reduced, and the service life of the probe will also be reduced.
When selecting a coating thickness gauge, try to choose a split type instrument. Due to the fact that the probe is a vulnerable component, it has a certain service life and is also a consumable material. The probe of the all-in-one machine cannot be repaired, and the price of replacing the probe is very high, close to the price of a new machine. And the split machine only needs to replace the probe.
