Emerson Digitaler Fisher™ FIELDVUE™ DVC6200S Digitaler Fisher™ FIELDVUE™ DVC6200S is an advanced digital valve controller with many advantages. It adopts linkage-free, non-contact valve position feedback technology, which eliminates direct contact between components, reduces wear and increases service life. The electronic equipment is well sealed and can adapt to various harsh environments. In terms of control performance, it responds quickly and controls accurately. The two-stage positioner design can quickly respond to large step changes and accurately control small set point changes. It also has travel control and pressure drop functions. When there is a valve position problem, it can automatically switch to I/P converter mode to ensure the normal operation of the valve. This product supports HART communication, which can access information from any position in the loop, reduce the probability of equipment contacting hazardous environments, facilitate rapid debugging of loops on local or remote valve components, and adopts modular design. Key working components can be replaced without removing field wiring and pneumatic piping. In addition, it saves a lot of hardware and installation costs through integrated control system installation hardware. The self-diagnosis function can perform health assessments when the valve is running, extend operating time, and support process and asset management decisions.
