Combines Differential Pressure Gage with Low/High Set-Points, Compact Size
Photohelic® Switch/Gage combines functions of a precise, highly repeatable differential pressure switch with a large analog pressure gage. Applications include air conditioning systems and pneumatic conveying.
Features
-
Gage reading unaffected by switch operation and will continue to read pressure even during power loss
-
Zero and range adjustments outside of gage means no disassembly in normal service
-
Solid-state design allows for switching in high cycle rate applications without degradation
Product Applications
-
Pneumatic Conveying
-
Air Conditioning Systems
-
Clean Rooms
