Mind the valves

Neles Automation has modified its ND800 digital positioner.

The ND800 automatically collects diagnostic data from an operational on-line valve and captured data trends identify those valves requiring maintenance.

Neles FieldBrowser software monitors networks of ND800 equipped valves and passes trend information to a database which, in turn, sends warnings via intranet, Internet and mobile ‘phones when alarm conditions are met.

Versions of the ND800 are compatible for use with HART and Fieldbus networks.
