Yokogawa provides wireless gas detection system

Hydrocarbon Engineering,

Yokogawa Electric Corporation and GasSecure AS, a Drager owned company, have announced the delivery of the world’s first SIL2 certified wireless gas detection system for use at an LNG facility in Northern Europe. The two companies have also begun promoting the unique capabilities of this system solution to companies that have a strong interest in maintaining safe and secure operations.

The system

The system uses GasSecure’s GS01 wireless gas detectors to measure hydrocarbon gas concentrations. Using the ISA100 Wireless communications protocol, the GS01 establishes a link with a Yokogawa YFGW510 access point and sends data to a host system via a Yokogawa YFGW410 field wireless management station. Although the GS01 uses a low power infrared sensor and is very energy efficient, it has a very fast response time. This capability of the GS01 and the utilisation of dual redundant communications by Yokogawa’s field wireless products make them essential components for the construction of a fast and highly reliable monitoring solution.

To meet customer safety requirements, GasSecure has made enhancements to the GS01 to obtain SIL2 certification for the device. For its part, Yokogawa has modified the YFGW410 so that it now supports the PROFIsafe safety communication standard, and has verified that both companies’ product perform and operate as specified.

The future

In the oil and gas, chemical, and other industries, safety is a paramount concern at production, storage and processing sites. Field wireless systems can be installed in difficult to wire locations and have lower cabling costs than wired systems. For these reasons, field wireless solutions are ideal for systems that collect production information such as flow rate, pressure and temperature. And unlike other wireless technology platforms, they can be used to construct systems that perform gas detection and other safety functions, and are well suited to this purpose. With the release of SIL2 certified wireless gas detection systems, Yokogawa will actively promote its field wireless equipment and systems, and will expand this business.
