Transcription of Series ADPS H.V.A.C. Differential Pressure Switch …
1 Differential Pressure SwitchesPRESSUREDWYER INSTRUMENTS, INC.| Differential Pressure SwitchWith dual Scale Field Adjustable Set Point KnobSeries ADPSthe Series ADPS Adjustable Differential Pressure Switch is designedfor Pressure , vacuum, and Differential pressures. The dual scaled adjustmentknob in inches water column and pascals allows changes to the switchingpressure to be made without a Pressure gage. The ADPS is available withsettings from in (20 Pa) up to 20 in (5000 Pa). The siliconediaphragm and PA body make the Series ADPS ideal for use with air andother noncombustible gases. The compact size, adjustment knob and low costmake the ADPS the perfect choice for HVAC Monitoring air filters and ventilators Monitoring industrial cooling-air circuits Overheating protection for fan heaters Monitoring flows in ventilation ducts Controlling air and fire-protection dampers Frost protection for heat exchangesSPECIFICAtIONSS ervice: Air and non-combustible, compatible Materials: Diaphragm material: silicone; Housing material: POM Switch body: ; Cover: Limits: Process and ambient temperature from -4 to185 F (-20 to 85 C).
