Druck IO-NEG-G-GEN-1 - Negative Gauge Pressure Generator
The GE Druck GE Druck Negative Gauge Pressure Generator is used to generate small -ve gauge pressure (Venturi effect) to enable control at zero gauge without the need for a vacuum pump.
The negative pressure generator is an option that is powered by a positive pressure supply (normally "instrument compressed air"). The generator provides a negative source for PACE in excess of - 350 mbar g.
