ADPS系列差压开关用于压力，真空，和差压的监测。设定点旋钮

上刻有英寸水柱和Pa刻度，无需差压表就能调整设定点。它的差

压范围从0.08英寸水柱(20Pa)到20英寸水柱(5000Pa)。采用硅胶隔

膜和PA6.6的工程塑料主体，用于空气或其它不燃气体。尺寸小，

带调整旋钮，价格低，使得ADPS差压开关最适合用于采暖通风行

the Series ADPS Adjustable Differential Pressure Switch is designed

for pressure, vacuum, and differential pressures. The dual scaled adjustment

knob in inches water column and pascals allows changes to the switching

pressure to be made without a pressure gage. The ADPS is available with

settings from 0.08 (20 Pa) up to 20 (5000 Pa). The silicone

diaphragm and PA 6.6 body make the series ADPS ideal for use with air and

other noncombustible gases. The compact size, adjustment knob and low cost

make the ADPS the perfect choice for HVAC applications.
