Series AT23000MR , 3000MRS
Using solid state technology, the Series AT23000MR & AT23000MRS ATEX/IECEx Approved Photohelic Switch/Gage with 24 VDC Power combines the functions of a precise, highly repeatable differential pressure switch with a large easy-to-read analog pressure gage.
Product Description
ATEX/IECEX APPROVED PHOTOHELIC SWITCH/GAGES WITH 24 VDC POWER
3000MR or 3000MRS Series in Flame-Proof ATEX/IECEx Enclosures
Gage reading is unaffected by switch operation and will indicate accurately even if power is interrupted. AT23000MR series employ versatile electromechanical relays with low amperage ratings-ideal for dry circuits. For applications requiring high cycle rates, choose AT23000MRS models with SPST (NO) solid state relays. Easy to adjust 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, they can be used in systems with pressures to 25 psig (1.725 bar). Optional construction is available for use to either 35 psig (2.42 bar) or 80 psig (5.51 bar). Flame-proof enclosures are available with glass window which allows for viewing of set point needles and process pressure. Compatible with air and other non-combustible, non-corrosive gases, they can be used in systems with pressures to 25 psig (1.725 bar). Optional construction is available for use to either 35 psig (2.42 bar) or 80 psig (5.51 bar).
FEATURES/BENEFITS :
• 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
• Flame-proof 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
