ESI - PR3900 - Hazardous Area Pressure Sensor

  • ATEX and IECEx certified
  • Designed for operation in zone 0, zone 20 and M1 mining
  • Wide choice of low and high pressure ranges
  • NACE corrosion resistant materials

Product description

The PR3900 gives a steady and exact intrinsically safe two wire output signal of 4-20mA. Pressure ranges available from 0-10 bar to 0-1,500 bar. The unique silicon-on-sapphire sensor gives a remarkable performance, stability and precision over a wide temperature range and gives superb chemical compatibility. Electrical connection is via a solid and sturdy polyurethane cable with integral vent tube for effective gauge venting to atmosphere, various process connections are available. Applications include any above ground explosive/hazardous environment installations, oil and gas industries and volatile chemical processing and storage.
