Pressure measuring instrument GB3002

differential pressureprocessfor compressed air

The GB 3002 pressure measuring instruments have two electronic (continuously adjustable) setpoint indicators which can be set and read independently from each other. This ensures that the indication of the actual value is not affected mechanically in any way. The switch relays are actuated by two phototransistors to control low and high limit and are additionally amplified by two power relays. This system is free of dead band. The switch setting can be done from the front very easily by external knobs at the front of the gauge. pneumatic differential pressure input and two electric potential-free switching output negative (vacuum) and differential pressure (measuring ranges from 0–60 Pa up to 0–30 kPa) the differential pressure value preset on the setpoint indicator is reached. by two LED (Duo-LED) with red-/green switch-over feature
