Advantages:

The PR3930 subsea pressure transducer 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 to 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 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.

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. Providing a half-duplex digital RS-485 output signal and 0-5 V analog output, the PR3930 provides high stability and repeatability for pressure ranges up to 1,500 bar. Intended for permanent immersion the product can withstand external pressures of up to 6,000 meters 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).
