Product Overview
3001MR-TAMP 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 0-1.0in 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
