Technology

GasSecure has developed a wireless infrared (IR) gas detector, the GS01, which operates with several orders of magnitude lower power consumption than today’s standard wired gas detectors. The battery powered GS01 is a field device specifically designed for safety and monitoring applications. Moreover, the GS01 detector fully supports the ISA100 Wireless™ standard for safe wireless operation of field instrumentation and is therefore very easy to deploy in an ISA100 environment.

For most safety applications, continuous monitoring is required and a short response time (also referred to as latency) must be guaranteed when a safety critical situation occurs. Fortunately, for gas detection the average bandwidth requirement for wireless communication is modest. The primary challenge in designing a wireless safety system is combining a guaranteed short latency with very low power consumption. In addition, full control of all network traffic is required and communication with the controller needs to meet reliability requirements according to SIL2 (Safety Integrity Level) guidelines as described in the IEC 61508 standard. Loss of contact with a field wireless device must be identified immediately.

GasSecure’s patented wireless communication concept SafeWireless™ meets the above requirements of fast response time, power efficiency and full control of network traffic and enables easy integration of the GS01 into safety instrumented systems (SIS) according to the IEC 61508 standard. As a part of a complete system and to achieve a total solution for safety communication loops, the GasSecure GS01 utilises PROFIsafe over PROFINET as communication tool for SIL applications. Redundant operation is possible for the entire safety system including the detector, gateway, and safety controller.
