The Ledpoint PRS, a sinter-free sensor solution from Amgas, is claimed to reduce gas detection system costs while increasing platform and personal safety.

It provides failsafe infrared gas detection and improves installation safety.

The control system and infrastructure do not require any upgrade work, thus minimising costs and system downtime.

An optional obscuration output enables planned maintenance.

Alternative flammable gas sensors based on optical absorption technology provide a high-reliability solution to the problems found with Pellistor sensors.

However, the technology used in current-design optical sensors means that their use requires significant cabling and control equipment modifications.

The Ledpoint PRS gas detector brings all of the advantages of sinter-free infrared detection technology to control systems configured to operate with Wheatstone Bridge-based field control technology, with no system modifications needed.

This plug-and-play sensor solution is designed to retrofit completely with Pellistor-based sensors.

It will fit the field-mounted terminal boxes, while the three-wire connection replicates a Pellistor circuit.

With minimal work, all the benefits of infrared can be incorporated into current installed systems, according to the company.

Diffusion and flow cell configurations are available for fixed-point and aspirator applications.

Following approval by independent test facilities, including Shell Global Solutions, Sira and Micropack for BP, and after extensive offshore field trials, the Amgas Ledpoint PRS is now being installed by UK, European North Sea and Middle East operators.

The Middle East application requires the use of the Ledpoint PRS HT high-temperature version, which is calibrated for operation up to 70C.

An installation reference list and a control card compatibility list are available on request.

The Ledpoint PRS solution will bring: total poison resistance; ultra-high-reliability sensor technology with no sinters to block; a temperature-corrected linear output; optical monitoring and fault diagnostics; and a fast response.

These features are further enhanced with the operational savings derived from reduced failures, reduced maintenance and reduced false alarms.
