Dungs GGW3A4 IP54 250V Ansluiting 0.4-3 Mbar 248673 High Burner Micro Air Pressure Switch For Burner

Product Description

 

PRODUCT DESCRIPTION

Explosion-proof according to ATEX II3GD
Adjustable pressure gauge for switching on and off or selecting a different circuit when the actual pressure value changes.The setpoint (switching point) is set by means of a setting wheel.
Suitable for gases and gaseous media as well as air, smoke and fumes.
GW ...A4 HP/2 X
Pressure gauge in overpressure range
The pressure acts via metal bellows against the adjuster spring and thus on the microswitch.
The pressure gauge operates without auxiliary energy.

GGW...A4/2 X
Differential pressure gauge in overpressure and underpressure range.
The pressure acts via metal bellows against the adjuster spring and thus on the microswitch.
The pressure gauge operates without auxiliary energy.

Technical description

The differential pressure switch GGW…A4 is an adjustable gas-dif ferential pressure switch as per EN 1854 for automatic burner controls. It is 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. The test nipple is integrated in metal housing as standard.

 

 

 

Approvals

EC type test approval as per EC Gas Appliance Directive: LGW…A4 CE-0085 AQ 0673 LGW…A4/2 CE-0085 AQ 0673 EC type test approval as per EC Pressure Equipment Directive: LGW… CE0036 Pressure switch Class "S" as per EN 1854. Approvals in other important gasconsuming countries.

 

Functional descriptionDifferential pressure switch operating in the over- and under-pressure ranges. The differential pressure acts on the membrane,
pressing it against the force of the adjusting spring and against the microswitch. The pressure switch operates without outside power.

Differential pressure switch GGW…A4 and GGW…A4-U

The switching apparatus reacts to the difference in pressure between the two pressure chambers [G 1/4 (+) G 1/8 (-)] and, if the pressure exceeds or drops below the setpoint, activates or switches an electrical circuit.

Unit selection

Unit selection If the lower pressure is [G 1/8 (-)] and excess pressure with respect to the atmosphere exists type GGW…A4 must be
employed. If the lower pressure is [G 1/8 (-)], and lower pressure with respect to the atmosphere exists type GGW…A4-U must be employed.

Overpressure switch GGW...A4 Pressure connection G 1/4 (+)

Single-acting pressure switch in the overpressure range. The switching mechanism responds if there is an overpressure which switches on, off or over to an electric circuit if the set reference value is exceeded or undershot.The pressure connetion G 1/8 may not be closed.

Low pressure switch GGW...A4-U Pressure connection G 1/8

Single-acting pressure switch in the overpressure range. The switching mechanism responds if there is a low pressure which
switches on, off or over to an electric circuit if the set reference value is exceeded or undershot. The pressure connetion G 1/4
may not be closed.
