ISA100.11a Field Wireless Devices
Field wireless devices based on the ISA100.11a industrial wireless communications standard are now available.
These wireless products include an EJX-B series differential pressure and pressure transmitter, a YTA series temperature transmitter, and an integrated field wireless gateway for field sensor networks. These field wireless devices are expected to satisfy a wide variety of requirements in the industrial automation field. Approved in September 2009, the ISA 100.11a standard presents the following advantages for use in industrial automation:
high reliability, suitability for a wide range of applications, flexibility and network expandability
and compatibility with existing wired systems. These wireless devices are designed to run on explosion-proof batteries that can easily be replaced in hazardous locations. The company plans to continue to develop various kinds of field wireless devices for both monitoring and control applications, and is also proposing the development of new field digital networks that integrate wireless and wired technologies.
