LGW...A1
factory-adjusted

Technical description
The LGW...A1 is a factory-adjusted differential pressure switch as per EN 1854.
- The LGW...A1 is suitable for switching a circuit on, off or over on changes in actual pressure value relative to the reference value set at the factory (reference value).
- 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.

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

Approvals in other important gasconsuming countries. Special designs for the North American market with UL, FM and CSA registrations.
