High Pressure Transmitter

  • Pressure ranges to 5,000 bar
  • Machined from one piece of Titanium
  • No seals or welds
  • High resistance to overpressure and pressure transients
  • Silicon-on-Sapphire (SOS) sensor technology
  • ATEX/IECEx option available for 4-20 mA versions
  • DNV GL approved


The HP1000 series extends the Silicon-on-Sapphire pressure sensor technology into very high pressure applications, with operating ranges up to 5,000 bar whilst maintaining an extremely high performance level.

The unique Silicon-on-Sapphire sensor technology provides outstanding performance and gives excellent stability over a wide temperature range.

The wetted parts and pressure diaphragm are machined from a single piece of titanium alloy meaning no weld joints and therefore high pressure integrity and overload capability. All titanium pressure port offers unbeatable corrosion resistance.

Standard pressure ranges:

HP10xx: 0 – 600 bar; 0 – 700 bar; 0 – 1,000 bar; 0 – 1,500 bar; 0-2,000 bar.

HP11xx: 0 – 2,500 bar; 0 – 4,000 bar; 0 – 5,000 bar (other ranges available)

Typical applications include:

  • Aerospace
  • Laboratory & test
  • Oil & gas monitoring
  • High pressure applications
  • General industrial environments
