With a field wireless system, the field devices at a plant are able to communicate wirelessly with host systems that perform functions such as monitoring and control. Wireless communications offer many advantages, including the ability to install field devices in difficult-to-
Yokogawa has been developing a wide variety of ISA100 Wireless compliant technologies and devices such as wireless adapters that allow conventional wired devices to access wireless networks. GasSecure specializes in the development, manufacture, and sale of low power, high reliability wireless gas detectors that are used to monitor for hydrocarbon leaks at offshore platforms, tank farms, industrial plants, and the like. GasSecure’s clients include major oil companies and their products are in wide use around the globe.
Under this agreement, Yokogawa will distribute GasSecure’s ISA100 Wireless gas detectors through its global sales and service network. The growing need to improve plant safety by installing more gas detectors and replacing out of date detection systems is driving the demand for wireless gas detectors, which have the added advantage of eliminating the need for wiring and thus are easier to install and cost less. As such, Yokogawa will be better able to satisfy its customers’ needs by incorporating wireless gas detectors in its field wireless system solutions. At the same time, GasSecure will be able to utilize Yokogawa’s global sales and service network to expand its wireless gas detector business.
Also, under the terms of a separate sales agreement that was reached in February of this year, GasSecure will sell Yokogawa’s field wireless system devices together with its own gas detection systems.
Features of GasSecure’s Wireless Gas Detectors
GasSecure’s wireless gas detectors detect leaks of hydrocarbon gas that can cause explosions. Utilizing ultra-low power infrared sensors, they perform measurements and send that information wirelessly to the host monitoring system. The key features of these detectors are as follows:
1. High reliability
As gas leaks are a frequent cause of major plant accidents, it is very important to have a highly reliable gas detection system that keeps plant personnel constantly up to date on any changes in gas concentration levels. With a five-second response time, GasSecure’s wireless gas detectors are able to perform highly specific and reliable infrared measurements of gas concentrations and wirelessly update a host monitoring system. With their ISA100 Wireless mesh network capability and their reliance on dual redundant communication paths between the detector and the host monitoring system, they are at least the equivalent of any wired alternative with respect to reliability.
2. High availability
With heated optical surfaces for removing condensation, GasSecure’s wireless gas detectors are suitable for use in highly humid environments and have excellent availability under a wide range of conditions, from tropical to arctic. The GasSecure detectors also utilize a stable triple wavelength infrared technology that eliminates the need for calibration for the entire lifetime of the product, something that is not possible with conventional instruments.
3. Low power consumption
The power consumed by these gas detectors averages just 5 mW thanks to the use of micro-electro-

Commenting on this agreement, Masatoshi Nakahara, director and senior vice president of Yokogawa’s Industrial Automation Platform Business Headquarters, said, “We selected GasSecure, a leading supplier of gas detectors, and believe that their best-in-class ISA100 Wireless solution will allow us to broaden the use of our field wireless systems.”
GasSecure’s CEO, Knut Sandven, also commented, "GasSecure selected Yokogawa for their reliable and high-quality wireless infrastructure. We are very excited about entering into this agreement as it will give us access to Yokogawa’s extensive global sales and service network."
* ISA100 Wireless, or ISA100.11a, is an industrial wireless networking technology standard developed by the International Society of Automation (ISA). ISA100 Wireless features high reliability, diverse applications, network extendibility, and high compatibility with wired communications standards such as Foundation™ fieldbus, HART®, and PROFIBUS. This standard is currently being discussed as IEC62734 by the International Electrotechnical Commission (IEC).
