Series ADPS Pressure Switch
Series ADPS adjustable differential pressure switch is designed for pressure, vacuum and differential pressures. The sealed adjustment knob allows changes to the switching pressure to be made without a pressure gage. The ADPS is available in settings from 0.08 in. W.C (20 Pa) up to 16 in. W.C. (4000 Pa). The silicone diaphragm and PA 6.6 body make the switch suitable for use with air and other noncombustible gases.
