Product Description

Air pressure sensor switch for gas detection

Product Description

Technical description
The GW…A5 pressure switch is a com- pact pressure switch as per EN 1854 for multiple actuators.
The pressure switches are  suitable for switching a circuit on, off or over on changes in actual pressure relative to the set switching point (reference value).
The switching point can be set eas- ily and quickly using a setting wheel provided with a scale without using a pressure gauge.
 

Application

Pressure switches for multi- ple actuators GasMultiBloc and DMV double solenoid valve which can be either mounted directly on housing or by using an adapter.
Suitable for gases of families 1,2,3 and other neutral gaseous media.

Approvals

EC type testing certificate as per:

• EC-Gas Appliances Regulation
• EC-Pressure Equipment Directive Pressure switch class "S" as per EN 1854.

Approvals in other important gas- consuming countries.
 

Functional description

Single-acting pressure switch in over- pressure range.
The pressure switches operate without any power supply.

Switching response GW…A5

Short response time during pressure fluctuations.

GW…A5/1

Slow response time during short-term pressure fluctuations by additional damping nozzle.

Pressure Switch

The GW…A5 is a single-acting pressure switch acting in pressure range. The control unit responds to pressure.
If the set reference value is exceeded
or undershot, the circuit is switched on, off or over.
