Digital valve controller detects conditions before failure
March 8, 2004
Digital valve controller has added a new green-yellow-red light performance diagnostics capability that makes control valve maintenance even easier. Using AMS Device Manager software with ValveLink® SNAP-ON™ application, the controller detects emerging conditions at the valve that could lead to valve failure. It analyzes and trends valve diagnostic data while the valve is in service without impacting the process. It displays the data graphically and provides a visual green, yellow or red indication of current valve performance with the color denoting the level of urgency. Users can instruct the software to run several performance diagnostics tests automatically. When the test sweep is complete, the software will pinpoint problems, show possible causes and provide clear recommended corrective actions. The online performance diagnostics tests can detect more than 200 fault conditions. The software documents test results in a preformatted Microsoft Word® format. FIELDVUE®.
