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.
