Differential pressure switch for air, flue and exhaust gases

The differential pressure switches LGW…A2… are adjustable differential pressure switchesas per EN 1854 for utomatic 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.

EC type testing certificate as per:
• EC-Gas Appliances Regulation
• EC-Pressure Equipment Directive

LGW…A2P test button
The LGW...A2P differential pressure switch is equipped with a test button.
The test button permits a service-friendly check of the safety function.
If the test key is pressed while the pressure exists, the connection to the pressure connection G 1/4 is interrupted and the pressure under the diaphragm is released. The microswitch of the pressure switch changes the contact position from NO to NC. If the test button is released, the pressure below the diaphragms is built up again and the microswitch changes to its original position
