Speedy, reliable loop valve testing

Third Quarter 2019 Hydraulic systems & components

Fluke’s new 710 mA loop valve tester allows technicians to source the 4-20 mA signal while it interrogates HART data to collect critical information about a valve’s position and status, providing quick checks of control valves while they are in place. With built-in test procedures and an intuitive interface, the Fluke 710 allows technicians to quickly and easily perform valve tests, while the valve test quick-check results provide at a glance diagnostics to make faster maintenance decisions.

With the tester’s built in HART communication function, technicians can source a 4-20 mA signal to cause the smart control valve to move, while simultaneously interpreting the valve’s HART feedback signal to determine whether the valve is moving to the expected position. In addition to positional information, the measured pressure delivered from the valve’s internal I/P (which moves the valve) can be seen with the HART communication protocol.

These preconfigured valve tests allow reliable and repeatable testing. Test results are stored in the memory, where they can be uploaded to the included ValveTrack analysis software.
