DUNGS LGW 10 A2P gas pressure switch

GAS PRESSURE SWITCH LGW 10 A2P

Technical description
The differential pressure switches
LGW…A2… are adjustable differential
pressure switchesas per EN 1854 for
automatic burner controls.
Suitable for switching a circuit on, off or
over on changes in actual pressure value
relative to the set reference value.
The reference value (switching point)
is adjusted on a setting wheel provided
with a scale. On LGW…A2P: test button
integrated in lower part as standard.

Application
Differential pressure monitoring in firing,
ventilation and air-conditioning systems.
Suitable for air, flue and exhaust gases
and other non-aggressive gases as differential
pressure switches; not suitable
for industrial combustion gases.

Functional description
Differential pressure switch in pressure
and vacuum range. The differential
pressure acts via the diaphragm against
the force of the setting spring on the
microswitch. The pressure switch operates
without auxiliary power.

Differential pressure switch
The control unit responds to differential
pressure. If the set reference value
(mbar) is exceeded or undershot, the
circuit is switched on, off or over.
