Protran ® PR3913 Control Valve Pressure Transmitter
Technical DataDescription
The PR3913 Valve-Mountable pressure transmitterhas been designed to meet the requirements ofthe sub-sea oil industry and is configured to mountdirectly to the industry standard control valve
flange arrangement.
The unique Silicon-on-Sapphire sensor technology provides
outstanding performance and gives excellent stability overa wide temperature range. The advanced sensor design
consists of a piezoresistive silicon strain gauge circuit, which isepitaxially grown onto the surface of a sapphire diaphragm toform 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 andprovides 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.

this product will provide a durable solution for long term
accurate pressure measurement even when permanently
situated in extreme depth sub-sea environments. The pressureconnection is achieved with an 8mm diameter stem withintegral dual redundant o-ring seal grooves. The fitting isconstructed from Inconel 625 for high chemical resistance.
Providing a two wire output signal of 4-20 mA with highstability and repeatability for pressure ranges up to 1,000 bar.
Intended for permanent immersion in pressurised dielectic oiland protected from ingress with a high pressure glass-to-metal
lead through the product can withstand external pressure up
to 3,000 metres depth water and provides secondary pressure
containment up to 1,650 bar. Units can be supplied withhyperbaric test certificates to 3,000 metres water submersion.
Electrical connection is via strong PTFE Raychem Flexlite leads.
Pressure ranges available from 0-200 bar to 0-1,000 bar.
An optional ATEX and IECEx approved version of this productis available for explosion protection for flammable gases (zone0), dusts (zone 20) and mining areas (group I M1).

Housed in fully welded body with wetted parts conforming to
the NACE recommendation for material corrosion resistance,
