Product Description

Dungs GGW10A4/2X IP65 1-10Mbar 248694 High Pressure Burner Control Compressor Switch Adjust Air Higher Explosion-Proof Grade

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

Adjustable pressure switches for ATEX requirements II3G and II3D. The pressure switches are suitable for activating, deactivating or switching a circuit if the actual value of the pressure changes compared to the set nominal value. The nominal value (switching point) is set by means of a setting wheel with scale.

 

 

 

Approvals

ATEX Manufacturer's declaration according to ATEX directive 94/9/EC: II3G and II3D EC type-examination certificate according to the EC gas appliance directive: CE-0085 AO 3220 EC type-examination certificate according to the EC pressure equipment directive: CE0036.

 

Functional description

GGW…A4/2 X and GGW…A4-U/2 X Differential pressure switch in overpressure and negative pressure range. The differential pressure acts on the micro switch via the membrane against the force of the adjusting spring. The pressure switch works without auxiliary power.

Media/use GW…A4 HP/2 X GGW…A4/2 X GGW…A4-U/2 X Suitable for gases of gas families 1, 2 and 3 and other neutral gases as well as
air, flue and exhaust gases. Version without non-ferrous material, suitable for gases up to max. 0.1 vol. % H2 S, dry

 

 

Device selection

GGW…A4/2 X and GGW…A4-U/2 X
If the lower pressure p2 (upper chamber) is a positive pressure compared to the atmosphere, type GGW…A4/2 X must be used. If the lower pressure p2 (upper chamber) is a negative pressure compared to the atmosphere, type GGW…A4-U/2 X must be used.

 

Overpressure switch GGW…A4/2 X Pressure connection G ¼

The control unit reacts on overpressure, which connects, disconnects or switches a circuit when exceeding or falling below a set nominal value. Simply acting pressure switch in overpressure range. The G ⅛ pressure connection must not be closed.

 

 

Minimum pressure switch GGW…A4-U/2 X Pressure connection G ⅛

The control unit reacts on negative pressure, which connects, disconnects or switches a circuit when exceeding or falling below a set nominal value. Simply acting pressure switch in negative
pressure range. The G ¼ pressure connection must not be closed.
