Electromagnetic compatibility requirements for vacuum pressure switches

The electromagnetic compatibility requirements of vacuum pressure switches mainly include the following aspects:

Electromagnetic disturbance emission limit: As an electronic and electrical device, the electromagnetic disturbance generated by vacuum pressure switches to the surrounding environment during their normal operation must not exceed a certain limit. This includes electromagnetic energy that propagates through space (radiated emission test) and electromagnetic energy that propagates along power lines, control lines or other signal lines (conducted disturbance test).

Electromagnetic immunity requirement: Vacuum pressure switches need to have a certain degree of immunity to electromagnetic disturbances existing in their environment, that is, electromagnetic sensitivity (EMS). This requires that the switch can still maintain a normal working state when facing electromagnetic interference, and will not experience performance degradation or malfunction due to the interference.

Comply with relevant standards: The electromagnetic compatibility testing of vacuum pressure switches must comply with a series of international and domestic standards, such as IEC, GB and other standards. These standards specify the test methods, test equipment and arrangements for electromagnetic compatibility, as well as the test grades and performance criteria. For instance, it may involve radiated electromagnetic field interference tests, oscillating wave interference tests, transient pulse tests, electrostatic discharge tests, etc.

When testing the electromagnetic compatibility of vacuum pressure switches, the actual application environment should also be taken into consideration. For instance, if a switch is to be used in an industrial environment, its electromagnetic compatibility requirements may be higher than those for residential or commercial Settings.
