LGW3A1 – Differential Pressure Switch

Technical description

The LGW…A1 is factory-adjusted differential pressure switch.

• Suitable for switching a circuit on, off or over on changes in actual pressure value relative to the set reference value set at the factory.
• Precise function by special switching system mounted in frictionless bearings.
• Electrical connection by means of a flat-type connector.
• Compact size.

Application

Differential pressure monitoring in firing, ventilation and air-conditioning systems. The LGW…A1 can be used as a pressure, vacuum or differential pressure switch for air and non-aggressive gases but not for industrial combustion gases.
