First Laser Open Path H2
S Gas Detector for safety related applications
Teledyne Gas and Flame Detection is unveiling its GD1 laser-based gas detector with full SIL2 approval. This ground-breaking development means that the GD1 SIL2 is the market’s first open- path gas detector for hydrogen sulphide (H2S) safety-related applications.
The global importance of SIL (Safety Integrity Level) has grown substantially in the oil, gas, petrochemical and other process industries over the past 10 years. It makes sense, therefore, that devices such as gas detectors demonstrate their suitability and competence in line with the latest SIL2 third-party certification.
The GD1 from Teledyne GFD first entered the market in 2011, with well over 800 units since deployed at oil and gas exploration and production companies throughout the Middle East and the rest of the world. With its new accreditation, the GD1 is now suitable for use in systems with SIL2 requirements. To provide some context, a typical SIL1 ATEX-certified gas detection device/ system will come complete with the functional approval according to IEC 60079-29-3 and require regular maintenance. The step from SIL1 to SIL2 requiresthe self-testing of hardware components, reduced maintenance intervals for sensors, strict requirements during development and thoroughly documented software.
Teledyne GFD’s innovative GD1 will prove attractive in SIL2 applications for a number of reasons, not least its unique, tunable laser diode that eliminates any environmental effects from sun, rain or fog. In fact, the GD1 can operate with up to 98% obscuration, boosting overall site safety. This capability is possible because light emitted by the detector travels as a cone from one point to another, rather than as a conventional straight beam. In other words, the beam expands after transmission and is almost a metre in diameter when it reaches the receiver. It can therefore penetrate harsh environments that competitor solutions may find difficult.
With its fast and fail-safe laser, the GD1 performs real-time automatic calibration and automatic proof testing, eliminating the need for manual intervention and reducing maintenance costs. Further advantages include low power consumption, very long lifespan and a high sampling/detection rate of 8000 times per second thanks to its ultra-stable optomechanical design and construction.
Furthermore, there is no potential of cross interference; the laser scans single absorption lines where there is no interference from other gases.
All of these added-value characteristics mean the GD1 can replace multiple standard detectors to cover the same risk, making it an economic solution that typically demonstrates real cost savings within two years.
