ATEX/IECEX APPROVED PHOTOHELIC® SWITCH/GAGE 3000MR or 3000MRS Series in Flameproof
ATEX/IECEx Enclosures
Using solid state technology, the Series AT-3000MR/MRS ATEX/IECEx Approved Photohelic® Switch/Gage combines the functions of a precise, highly repeatable differential pressure switch with a large easy-to-read analog pressure gage. Gage reading is unaffected by switch operation and will indicate accurately even if power is interrupted. The AT102-3000MR series employs versatile electromechanical relays with low amperage ratings-ideal for dry circuits. For applications requiring high cycle rates, choose AT102-3000MRS models with SPST (NO) solid state relays. Easy-toadjust set point indicators are controlled by knobs located on the gage face (accessible opening case after de-energizing instrument). All models provide both low and high limit control. Compatible with air
and other non-combustible, non-corrosive gases. Flameproof enclosures are available with a glass window which allows for viewing of set point needles and process pressure. Compatible with air and other noncombustible, non-corrosive gases.

BENEFITS/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
• Flameproof enclosure with optional glass window and aluminum housing protects the device in
hazardous areas while giving local visibility to process pressure and set point status
• Increased response time at low pressures with LD port configuration
APPLICATIONS • Hazardous area pressure measurement and switching
• Pneumatic conveying
• Air conditioning systems
• Clean rooms
• Fume exhaust systems
