Yokogawa Electric Corporation announces that in December it will begin providing sensor manufacturers a new wireless communications module with a built-in antenna. This new module is intended for use in wireless sensors, and will be provided to companies that develop and manufacture these products. Yokogawa has already concluded a contract to license the use of this wireless technology to New Cosmos Electric Co., Ltd., a gas detector manufacturer.
It is expected that this module will drastically reduce the amount of time required to develop ISA100.11a*1 compliant wireless sensors.
Yokogawa advocates the Wireless Anywhere concept for the plant-wide use of wireless communications technology and is working hard to promote the use of ISA100 Wireless™*2 communications technology solutions. As part of this strategy, we have developed this module.
In plants, various sensors are used to measure temperature, pressure, level, gas concentration, vibration, and so on. To develop wireless sensors for such applications, not only do manufacturers need to acquire the necessary wireless technologies, they must also comply with the radio regulations and explosion protection standards in each country. Based on the various technologies and knowledge that it has acquired through the development of field wireless systems, Yokogawa has developed a wireless communications module with a built-in antenna that can help sensor manufacturers significantly shorten the time needed for developing wireless sensor products.
New Cosmos Electric, a company with a solid track record in providing gas detection solutions to the manufacturing industry, is planning to develop a wireless gas detector. In view of its high reliability, flexible applicability, and network expandability, the company has decided on an ISA100 Wireless solution for this field wireless product. Accordingly, Yokogawa will provide this module and the technology assistance needed to develop a wireless gas detector.
Advantages of Using This Module
1. Speeds up wireless sensor development
This module is comprised of an antenna and associated wireless communications circuitry. By installing this module on a sensor that includes components such as an interface circuit and power supply, a sensor manufacturer can greatly speed up the process of developing an ISA100 Wireless sensor.
2. Complies with radio regulations and explosion protection standards
Based on its wealth of technologies and expertise in the development of field wireless devices, Yokogawa has been able to design a module that complies with over 100 countries’ radio regulations as well as all the major explosion protection standards. Sensor manufacturers thus do not need to certify that their sensors meet such regulations and standards, drastically shortening development time.
3. Compact and lightweight
Including the built-in antenna, this module is only 116 mm long and 23 mm in diameter, and weighs just 100 grams. This allows the development of compact and lightweight field wireless sensors.

Yokogawa's Approach to Field Wireless Communications
Field wireless systems utilize wireless communications networks to link a plant’s field devices with its control systems. Yokogawa designs these networks to comply with the ISA100.11a standard. In addition to being highly reliable, suited for a wide range of applications, and expandable, they are compatible with wired communications standards such as FOUNDATION™ fieldbus, HART®, and PROFIBUS. The International Electrotechnical Commission (IEC) is currently considering the adoption of the IEC62734 standard, which is based on ISA100.11a.
Yokogawa released the world’s first ISA100.11a compliant field wireless system devices and wireless pressure and temperature transmitters in July 2010. In addition to enabling sophisticated control techniques in continuous processes, this gave customers a wider range of devices to choose from. In July 2012, Yokogawa released a reliable, large-scale field wireless system for use in plants and is now expanding the range of suitable monitoring and control applications for wireless technologies and devices.
In line with the Wireless Anywhere concept, Yokogawa will continue to expand its lineup of ISA100 Wireless solutions and provide either free of charge or on a license basis various fundamental technologies in modular form.
