Using solid state technology, the Series 3000MR & 3000MRS Photohelic® Switch/
Gages combine the functions of a precise, highly repeatable differential pressure
switch with a large easy-to-read analog pressure gage employing the durable,
time-proven Magnehelic® gage design. Used in Clean rooms, 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
• Optional stainless steel bezel is the same installation diameter as Magnehelic® gage
and simplifies field upgrade to Photohelic® switch/gage
