PR3930

The PR3930 subsea pressure transmitter has been designed to meet the demanding requirements of pressure measurement at deep levels of immersion, especially in oil industry applications. It can be configured to suit a multitude of applications and with proprietary RS-485 interface, each sensor can be allocated a unique device address and connected in series with other sensors and devices on the same communications link.

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

Housed in a fully welded body, this product will provide a durable solution for long-term accurate pressure measurement even when permanently situated in extreme depth sub-sea environments. Intended for permanent immersion, the unit can withstand external pressures of up to 6,000 metres depth water. Units can be supplied with hyperbaric test certificates to 3,000 metres water submersion. Electrical connection is via 8 pin Subconn MCBH8M connector (6 pin option available).

Standard pressure ranges:

0 -100 bar; 0 – 250 bar; 0-400 bar; 0-600 bar; 0-1,000 bar; 0 – 1,500 bar (other ranges available)

Typical applications include:

• ROV and deep sea test equipment
• Permanent immersion at extreme depths
• Subsea environments
