NPN Automatic Air Vacuum Pressure Switch 

NPN Automatic Air Vacuum Pressure Switch The NPN vacuum pressure switch rated pesssure range is -101.3~0.0 kpa. It suit for filtered air, non-corrosive, non-flammable gas. The air pressure sensor adopts high-precision and stable pressure sensor and transmission circuit, and then realizes the detection,display, alarm and control signal output of the medium pressure signal through the special CPU modular signal processing technology.    Name:   Vacuum Pressure Switch   Display:   3-color digital LCD display   Diaplayable unit:   KPa, MPa,kgf/m2bar.psi.inHg mmHg   Response time:   <2.5ms…
