Heavy Duty Pressure Transmitter

  • Silicon-on-Sapphire sensor technology for outstanding performance and reliability
  • Pressure ranges up to 1,500 bar
  • All stainless steel, robust construction for harsh environments
  • Wetted parts in various materials
  • ATEX/IECEx option available, including M1 for mining applications


The PR9000 Series pressure transmitters have been designed to meet the requirements of the majority of demanding industrial and process applications for pressure measurement requiring an output of 4-20 mA.

With robust stainless steel housing construction, this range of pressure transmitters incorporates the unique Silicon-on-Sapphire sensor technology which provides outstanding performance and gives excellent stability over a wide temperature range. The sensor can endure high over-pressures and provides superb corrosion resistance with virtually no hysteresis. The outstanding insulation properties of the sapphire allows the sensor to operate over a very wide temperature range without loss of performance.

An important feature of this transmitter is the easily accessible screw terminal connections and the zero/span potentiometers conveniently positioned inside the screw cover head for simplified on-site adjustment and installation. Cable entry to the transmitter head is through a PG9 gland or an optional M20 conduit fitting. Pressure connection is 1/2″ BSP as standard, 1/2″ BSPT, 1/2″ NPT are also available together with hygienic and process flanges with media barriers. Pressure ranges are 0-100 mbar to 0-1,500 bar.

Typical applications for this series of standard transmitters includes mechanical and civil engineering, process plant, production test facility, water resource, and power generation installations, and for any fluid or gas application requiring stable, repeatable and accurate pressure measurement.

An optional ATEX and IECEx approved version of this product is available for explosion protection for flammable gases (zone 0), dusts (zone 20) and mining areas (group I M1).
