|Pressure Switches

For ZSE series vacuum pressure switches, if vacuum release (purge) causes pressure outside of the rated pressure range, will it damage the product?

If the vacuum release pressure is 500 kPa or less (or 200 kPa for some of the older models), it will not cause any damage to the product. However, a pressure error may be generated each time purge pressure is applied.
Also, depending on the set value, unwanted output may occur, so use a set value that will not produce any undesired effects.
