  Transmitter passes new Fieldbus Standard
Two products from Yokogawa are the world's first instruments to pass new interoperability tests specified by the Fieldbus Foundation. The enhanced EJA Series pressure transmitter and the YVP valve positioner both meet the requirements of the new FF (Foundation Fieldbus) R4 interoperability test system. The EJA A Series is an evolution of Yokogawa's family of field proven high-performance pressure transmitters, and features Yokogawa's digital sensing technology known as DPharp (high-accuracy resonant pressure). As a result, there is no need for analogue/digital conversion, providing a totally digital measurement path from sensor to workstation. The YVP Series is a family of intelligent valve positioners which provide a control system with feedback on the actual valve position as well as several other variables which can be used for troubleshooting and/or diagnostics. The YVP will mount directly on to existing valves, making it easy to upgrade an analogue valve to fieldbus technology. Both product ranges incorporate link active scheduler (LAS) functionality and a PID function block. 'Interoperability is arguably the most important challenge facing the Fieldbus Foundation, since free communication between devices is a pre-requisite of any commercially viable Fieldbus system', comments David Tipton, Sales & Marketing Director of the process measurement products division of Yokogawa UK Ltd. 'The Fieldbus Foundation is actively encouraging device manufacturers to re-test currently registered field devices with the new R4 interoperability test, and we at Yokogawa are at the forefront of these developments.' ________________________________________________ For further information, contact:- Yokogawa UK Ltd.
