Yokogawa Expands Its Lineup of ISA100.11a Compliant Wireless Devices

Keywords: Wireless, Pressure Transmitters, Temperature Transmitters, Wireless Management, Differential Pressure, High-Gain Antenna.

Yokogawa Electric recently announced at the ARC Advisory Group Orlando Forum 2012 that it has developed three new wireless system devices and enhanced existing wireless pressure and temperature transmitters, all of which are compliant with the ISA100.11a wireless standard. The first of these products are scheduled to be released in March 2012.

These new wireless products can be used to construct highly reliable large-scale plant-wide networks, and may also be incorporated in small- and medium-sized networks that already utilize Yokogawa's existing products, substantially expanding their capability. This is in line with the company's Grow concept of enabling customers to expand their plant wireless networks while making full use of existing assets.

The new products include a field wireless management station which is a new gateway device for connecting production control systems and field wireless devices, including system and security management functions; a field wireless access point which is a new router device for connecting field wireless devices and gateways; and a field wireless media converter which is a new device that converts data from 100BASE-TX to 100BASE-FX. Both EJX-B series of differential pressure/pressure transmitters and YTA 510 temperature transmitter enhance their capabilities with detachable remote antenna and low-power consumption design.

Each of the new field wireless system devices has a backup device. If the communications link is broken or a hardware failure occurs in any of these devices, automatic switchover to the backup device is implemented and the communications link is restored, ensuring uninterrupted communications with field wireless devices and increased reliability in process monitoring.

Compared to the Yokogawa's entry-level gateway model YFGW710, the new field wireless management station can manage up to ten times the number of field wireless devices. Both of them support communications with 100BASE-TX, 100BASE-FX and wireless LAN networks, allowing for both the expansion of plant wireless networks and the full use of existing assets.

Both the EJX-B and YTA 510 transmitters now come with an antenna that can be removed and mounted in a separate location, extending the communications range. A high-gain antenna option is also available that can extend the communications range up to four times. And through the incorporation of low power consumption design features, battery life is now twice as long.
