3020MR

3020MR is a series 3000MR Photohelic® switch/gauge which combines the functions of a precise, highly repeatable differential pressure switch with a large easy-to-read analogue pressure gauge employing the durable, time-proven Magnehelic® gauge design. The switch setting is easy to adjust with large external knobs on the gauge face. gauge reading is unaffected by switch operation - will indicate accurately even if power is interrupted. 3000MR is employ versatile electromechanical relays with gold over silver contacts - ideal for dry circuits. Typical applications include pneumatic conveying, air conditioning systems and clean rooms.

• Pressure range from 0-20in water column
• Gauge reading unaffected by switch operation, will continue to read pressure even during power loss
• Zero and range adjustments outside of gauge means no disassembly in normal service
• Temperature limits from 20 to 120°F (-6.67 to 48.9°C) (gauge)
• Each set point has 1 form C relays (SPDT) switch type
• 24VDC, regulated 10% power requirements
• 18" cable assembly with 8 conductors. optional lengths to 100'
• Diaphragm in vertical position
• Adjustable knobs on face
