Laser open path gas detector - SIMTRONICS - #1

SIL2

The GD1 has been designed with features that provide an effective response to the detection of gas hazards in a wide range of industrial environments from offshore production facilities to wastewater treatment plants.

At the heart of the detector is a tuneable laser diode that eliminates environmental effects from sun, rain and fog. The laser scans single absorption lines where there is no interference from other gases.

Unlike traditional methods for detecting H2S (MOS or EC cell) the GD1 needs no reclaibration and can replace multiple standard detectors to cover the same risk.

The complete optomechanical design and construction is so stable that an ultra fast speed of response can be achieved whilst providing unparalleled service life and detector stability, thus saving on maintenance and service costs.

The GD1 is also available with a dual output gas configuration. A single laser can be used to detect both Methane and Hydrogen Sulphide, hence reduced cabling, installation and maintenenace costs.

Supplied with worldwide hazardous area approvals, e.g. ATEX, CSA. Suitable for use in SIL 2 systems.
