Digital positioner expands use

-- Control Engineering, 11/1/2000

Shrewsbury, Mass.-Neles Automation's ND800 digital valve positioner technology now can be used with a wide range of manufacturer's rotary or linear valves. The ND800 provides extensive monitoring for diagnostics and is capable of improving a control valve's speed of response and positioning accuracy for substantive improvements in process stability. The ND800 automatically collects diagnostic data from the valve online and captures trend data to identify valves requiring maintenance. It also identifies valves that are performing well, avoiding unnecessary preventive maintenance costs. The ND800's Field-Browser software can monitor networks of so-equipped valves passing information to a database and sending warnings via Internet, intranet, and mobile phone.
