DVC2000 vs DVC6200: What’s the Difference Between Fisher FIELDVUE Digital Valve Positioners?

Both Fisher DVC2000 Digital Valve Positioner and Fisher DVC6200 Digital Valve Positioner are perhaps two-star products in Emerson's Fisher FIELDVUE product range. They are both digital valve controllers, but what are the distinctions between them? Which one should I pick? Today we will take a good look at the Fisher DVC 2000 and DVC 6200. 

In this blog, we will explain:

● Fisher FIELDVUE DVC6200 & DVC2000.

● Fisher DVC2000 vs Fisher DVC6200.

● Which Fisher Digital Valve Positioner Should We Choose?

The Fisher FIELDVUE DVC2000 Digital Valve Controller is one of Emerson's top-selling intelligent valve positioners. Its tiny form is appropriate for smaller valves with short strokes. In addition, the dvc2000 fisher has the ability to communicate, in addition to controlling valves, which is highly useful.

Fisher FIELDVUE DVC6200 Digital Valve Controller is a new version of the DVC2000. It has all the functions of dvc2000 positioner and also has more powerful functionalities that fieldvue dvc2000 does not have. The DVC6200 Fisher is for bigger valve sizes, with more configuration freedom and more sophisticated monitoring capabilities.

1. Difference In Design Philosophy:

With its small size, ease of installation and configuration and economical operation the DVC 2000 is better ideal for routine procedures. However, the DVC 6200 has improved diagnostic and higher control performance making it more suitable for complicated processes in critical applications.

2. Difference In Valve Diagnostic Capability:

The diagnostic capabilities of the Fisher DVC6200 Positioner are clearly greater. The Fisher DVC2000 Positioner is more complex and sophisticated than the DVC 2000 and incorporates not only the basic diagnostic functions of the DVC 2000, but also additional diagnostic functions not found on the DVC 2000.

3. Difference In Feedback Technology:

For feedback technology, DVC2000 Digital Valve Controller uses a non-contact feedback system based on magnetic sensing technology, and DVC6200 Digital Valve Controller uses a linkless feedback system with better vibration resistance and long-term stability.

4. Difference In Communication Capability:

Both the DVC 2000 and DVC 6200 are equipped with 4-20mA input and HART communication for communication, while the DVC 6200 is further equipped with other communication options.

5. Difference In Installation And Maintenance:

The installation and maintenance of the DVC 2000 FIELDVUE and DVC 6200 FIELDVUE are identical, and both feature a great human-computer interface.

And as they are from the same brand and series, the DVC6200 can be directly upgraded and, in most cases, directly replace the DVC2000.

The Fisher DVC2000 Digital Valve Positioner and the Fisher DVC6200 Digital Valve Positioner are both excellent. The FIELDVUE DVC6200 is an upgraded version, more advanced and better performing than the FIELDVUE DVC2000. Choose the one that best suits your needs.
