Product Description

Germany Dungs GW50A4 250V IP 54 Pressure Monitor 2.5 -50 Mbar High Burner Gas Control Compressor Switch Adjust Air

Product Description

 

Technical description

The GW.... A4 pressure switches, the pressure limiters ÜB A4 and NB A4 and the double pressure switch GW A4 / GW
A4 are adjustable pressure switches for automatic burner controls. They are suitable for switching a circuit on, off or over on changes in actual pressure value relative to the set reference value. There ference value(switching point)is adjusted on a setting wheel provided with a scale. Test nipple integrated in metal housing as standard.

 

Application

Pressure monitoring in firing, ventilation and air-conditioning systems. Suitable for gases of families 1,2,3 and other neutral gaseous media.

 

Approvals

Approvals

EU type test approval as per EU Gas Appliance Directive. TÜV (German Technical Inspectorate) inspection for pressure switches of special construction as per TRD 604 and VdTÜVTechnical Data Sheet, edition 100/1, as well as Class "S" as per EN 1854.

GW...A4 CE-0085AO0012

ÜB...A4 CE-0085AO0026

NB...A4 CE-0085AO0039

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

 

Functional description

Single-acting pressure switch or pressure limiter in pressure range. The pressure switches and/or pressure limiters work without using any auxiliary power.

GW A4 pressure switch

The control unit responds to pressure. If the set reference value is exceeded or undershot, the circuit is switched on, off or over.

ÜB A4, NB A4 pressure limiters

The control unitresponds to pressure. Interlock is performed when the set reference value is exceeded or undershot.

The "Locked" switching state is indicated by a glow lamp. Restart is only possible by activating the reset
button on the setting wheel of the pressure limiter after the operating pressure is attained.

ÜB A4: Switches and locks when the set pressure is exceeded.

NB A4: Switches and locks when the set pressure is undershot.

Double pressure switch GW A4 / GW A4

CombinationoftwoGWA4singlepressure switches flanged together. The setting of the two reference values is performed separately and independently. This permits a combination of different reference value setting ranges. The same medium and pressure are applied to the two control units.
