LGW Series

Technology
Adjustable differential pressure switches according to EN 1854. The pressure switches are suitable for activating, deactivating or switching a circuit if the actual value of the pressure changes compared with the set nominal value. The nominal value (switching point) is set by means of a setting wheel with scale.

Differential pressure switch
LGW...A2, LGW...A4 The control unit reacts to differential pressure, which connects, disconnects or switches a circuit when exceeding or falling below a set nominal value.

Function
Differential pressure switch in the positive and negative pressure range. The differential pressure acts on the micro switch via the membrane against the force of the adjusting spring. The pressure switch works without auxiliary power.
