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.'
