Diff. press. gauge ATEX GGW 3 A4-U/2 X Dungs, -0.4 to -3.0 mbar, 248390 248390

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.
