The GS01 is a wireless infrared gas detector designed for the nonstop detection of flammable hydrocarbon gases and vapors in oil and gas facilities. Built with intrinsic safety and SIL certification, this transmitter operates entirely without wires — both in communication and power. Its wireless design makes it a versatile and budget-friendly option for expanding existing setups, upgrading infrastructure, or deploying in new greenfield developments.C4.
• Installations in demanding conditions
• Saving time and money throughout the project
• Saving time and money during operation
• Safe, wireless communication
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. GS01 wireless transmitter requires no cable installation, either for signal transmission or for its power supply. As such, 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 for 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.
