Instrument Selection
current­to­pneumatic instruments. In addition to the
traditional function of converting a current signal to a
pressure signal, DVC6200 digital valve controllers,
using HARTr or FOUNDATION™ fieldbus
communications protocol, give easy access to
information critical to process operation.
An excellent selection of sensitive and accurate
instruments is available for 685SE and 685SR
spring-return piston actuators. These include the
FIELDVUE DVC6200 digital valve controller, as well as
volume boosters.
For additional information, refer to Fisher bulletin
