LGW A2, LGW A2P, LGW A2-7: Differential Pressure Switch for air, flue and exhaust gases

The differential pressure switches LGW…A2… are adjustable differential pressure switches as 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.

Differential pressure monitoring in firing, ventilation & air conditioning systems. These are not suitable for industrial combustible gases.
