How to solve pressure switch display problem

1. Wotian visits a large customer’s company

Recently, Wotian received a feedback from a large customer about pressure switch PCM710.  It has been displayed on the meter after power-on, but the value displayed does not change after adding pressure (pressure is changing).

WoTian urgently sends a research and development team to the site to investigate the problem and find out the reasons.

3. Wotian investigates on site

4. Wotian adjusts on site

After a series of tests and research, Wotian discovers the reason. When the motor is energized, a magnetic field is generated, and the generated magnetic field will interfere with the pressure switch operation, resulting in abnormality of the pressure switch.

5. Wotian product application

After finding this conclusion, Wotian formulates an improvement plan to enhance the anti-interference ability of the product, and improves the EMC (Electro Magnetic Compatibility) anti-interference level so that the product can be used normally.
