Coval - Pneumatic Vacuum Switch, PSE100PK series

Pneumatic Vacuum Switch, PSE100PK series

Presentation: The PSE100PK vacuum switch with pneumatic output is used to check the vacuum level in the circuit.
It is recommended for measuring slowly changing vacuum levels such as regulating or checking vacuum levels in networks over 1 liter.
This vacuum switch exists in two versions : NO version recommended for the "air saving" function on a venturi and NC version for the "safety" function (object detected, etc.) and "SFC signal".
