The Drager GasSecure GS01 is a wireless infrared gas transmitter for continuous monitoring of flammable hydrocarbon gases and vapours in the oil and gas industry. The intrinsically safe and SIL-rated transmitter features completely wireless signal transmission and power supply. This makes the GS01 a flexible and cost-efficient solution for plant expansions, upgrades, and new greenfield projects.
Installations in demanding conditions
On offshore platforms or FPSOs, at tank farms and refineries – safety-related measuring points are everywhere in the oil and gas industry. Some of these measuring points are extremely difficult if not impossible, to monitor using wired gas detection devices. In contrast, the GS01 wireless transmitter requires no cable installation, either for signal transmission or for its power supply. The installation is easy and uncomplicated, and the transmitter sends its signal to the access point up to 500 metres away. No cable conduits are required for the power supply or signal transmission. Plus, the GS01-EA product variant with separate antenna can be installed inside machines or buildings where signal transmission is impossible due to shielding.
For temporary applications, such as maintenance work on petrochemical plants or exploratory drilling, the GS01 offers you maximum flexibility. It can be seamlessly integrated into your existing safety features. Even technically complex installations, such as on the rotating tower of an FPSO, can now be carried out without hassle.
Saving time and money throughout the project
The project costs with GS01 can be significantly lower than those for wired installations; for example, the installation cost is typically reduced with 60 to 80 %. Wireless communications and battery power decrease the need for cables, junction boxes, and control cabinets. Site installation work is significantly reduced with the ability to pre-configure all devices in advance. Additionally, planning, configuration and documentation of the system is minimised. This is made possible by the intelligent design of the GS01. The transmitter draws less than 5 milliwatts of power. Depending on the ambient conditions; it can run for up to 2 years without the batteries needing to be replaced. The intrinsically safe design allows the battery pack to be replaced easily, even in the hazard area.
Saving time and money during operation
Infrared sensor technology is taken to the next level using patented MEMS (Micro Electromechanical System) optical filters. MEMS is very long-term stable and eliminates the need for re-calibration, which directly reduces maintenance costs. The infrared detection with MEMS operates at three different wavelengths and includes heated-optics to prevent condensation in the sensor.
Safe, wireless communication
The SIL2-capable GS01 uses the ISA100.11a wireless standard for wireless communication. A great benefit of this object-based standard is the possible embedding of foreign protocols, including the SIL3-certified safety protocol PROFIsafe. In combination with GasSecure’s patented SafeWireless communication concept for fast and secure transfer of measurement data, this enables easy integration of the GS01 into safety instrumented systems (SIS) with a fully SIL2-capable signal chain. Furthermore, the open ISA100.11a standard supports easy integration of other field devices into the wireless network.
