English The differential pressure switch LGW...A2... is an adjustable differential pressure switch in accordance with EN 1854 for combustion systems. It is suitable for switching a circuit on and off or switching it over when the actual pressure value changes in relation to the setpoint value. The setpoint (switching point) is set using a dial with scale. Test button integrated in the base as standard for LGW...A2P.
Differential pressure monitoring in combustion, ventilation and air conditioning technology. Suitable for air, flue and exhaust gases and other non-aggressive gases as a differential pressure monitor, not suitable for technical fuel gases.
Test button LGW...A2P
The LGW...A2P differential pressure switch is equipped with a test button. The test button enables service-friendly checking of the safety function. If the test button is pressed when pressure is applied, the connection to the G1/4” pressure connection is interrupted and the pressure under the diaphragm is released. The microswitch of the pressure switch changes the contact position from NO to NC. When the test button is released, the pressure under the diaphragm builds up again and the microswitch changes to its original position.
