PROTRAN PR3915

Performance:

  • Two pressure sensors and electronics for reliable dual redundancy
  • Submersion to 3,000 meters (10,000 ft) sea level
  • Pressure ranges available to 1,000 bar (15,000 psi)
  • Silicon-on-Sapphire sensor technology for outstanding performance

Advantages:

The PR3915 Dual Redundant Subsea pressure transmitter has been designed to meet the requirements of the sub-sea oil industry Valve-Mountable and is configured to mount directly to the industry standard control valve flange arrangement.

The unique Silicon-on-Sapphire sensor technology provides outstanding performance and gives excellent stability over a wide temperature range. The advanced sensor design consists of a piezoresistive silicon strain gauge circuit, which is epitaxially grown onto the surface of a sapphire diaphragm to form a single crystalline structure. The sapphire sensor element is then molecularly bonded to a titanium alloy sub-diaphragm. This enables the sensor to endure higher over-pressures and provides superb corrosion resistance. The sensor exhibits virtually no hysteresis and excellent long-term stability. With outstanding insulation properties, the sapphire substrate allows the sensor to operate over a very wide temperature range without loss of performance.
