Pneumatic Vacuum Switch, PSE100PK series

The PSE100PK Pneumatic Vacuum Switch is used to control the vacuum level in the circuit.

It is recommended for measuring slowly changing vacuum levels, such as regulating or monitoring the vacuum level in networks larger than 1 liter

This vacuum switch is available in two versions:

• The NO (Normally Open) version is recommended for the "air saving" function in Venturi systems.
• The NC (Normally Closed) version is recommended for the "safety" function (product detection, etc.) and the "SFC signal".

Advantages

• 2 different versions: NO or NC
• Setting range:
• NC: -250 to -830 mbar / NO: -350 to -880 mbar
