pr-282

Mamac System PR-282 Differential Pressure Sensor/Transducer

The PR-282 incorporates sophisticated integrated circuits and new fused silicon monolithic cavity pressure sensors to not only provide a high level, fully conditioned, and temperature compensated output, but also to offer up to six (6) pressure ranges.

Features of Mamac System PR-282:

  • 100% solid-state fused silicon pressure sensors
  • Rugged, leakproof stainless steel monolithic pressure cavities with no welds, O-rings, seams, or bonds
  • Wide 12 to 40 VDC/12 to 35 VAC unregulated supply voltage
  • Three temperature-compensated humidity output versions: 4-20 mA
    2-wire or field selectable
    0-5 VDC / 0-10 VDC
  • NIST traceable calibration
  • Rugged NEMA-1 (IP-30) enclosure
  • Short circuit and reverse polarity protected
  • Conforms to EMC and RoHS standards
