3000MRS-50MM

3000MRS-50MM is a series 3000MRS 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. For applications requiring high cycle rates, choose 3000MRS model with SPST (N.O.) solid-state relays. Typical applications include pneumatic conveying, air conditioning systems and clean rooms.

• Pressure range from 0-50mm 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)
• 1/8" female NPT (duplicated side and back) process connections (gauge)
• Each set point has a solid state relay switch type
• 20 to 280VAC (47 to 63Hz) switching voltage
• 1A (AC) maximum, 0.01mA (AC) min, (2) SPST NO switching current
• 24VDC, regulated ±10% power requirements
• Adjustable knobs on face
