|Pressure Switches

Vacuum pressure switch, ZSE series can reach out of the applicable pressure due to vacuum break (purge). Isn't it broken?

When vacuum break pressure is less than the withstand pressure of 500kPa (for the old ZSE1/2/3/4/5/6 series was 200kPa), the sensor diaphragm should not get damaged.
However, pressurize error can arise, whenever purge pressure is applied. Also, depending on set value, unnecessarily large pressure can be supplied and so set the value that may have less impact.
