Teledyne Gas and Flame Detection has launched its GD1 laser-based gas detector with full SIL2 3rd party approval
The GD1 SIL2 is the market´s first open-path gas detector for hydrogen sulphide (H2S) safety-related applications, according to the company.
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 more than 1600 units since deployed at oil and gas exploration and production companies throughout the Middle East and the rest of the world.
With its new certification, the GD1 is now suitable for use in systems with SIL2 requirements. The step from SIL1 to SIL2 requires built-in automatic self-testing of hardware components, meaning reduced maintenance intervals for sensors, and reduced downtime. GD1 complies to the latest standard for IEC 60079-0:2017 (IECEx).
Teledyne GFD´s GD1 feature a unique customised tunable laser diode that eliminates environmental effects from sun, rain or fog. It can operate with up to 98% obscuration, boosting overall site safety, and can penetrate harsh environments that competitor solutions may find difficult.
With its fast and fail-safe laser, the GD1 performs real-time dual automatic calibration and automatic proof testing, thus eliminating the need for manual intervention and reducing maintenance costs. Further advantages include low power consumption (15W), very long lifespan and a high sampling/detection rate of 8,000 times per second, thanks to its ultra-stable optomechanical construction.
