The new Fluke 710 mA Loop Valve Tester allows technicians to source the 4-20 mA signal while it interrogates HART data about the valve’s position and status, providing quick checks of control valves while they are in place.
Built-in test procedures and an intuitive interface allow technicians to quickly and easily perform valve tests, while the quick-check results provide at-a-glance diagnostics to make faster maintenance decisions.
With its 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, measured pressure delivered from the valve’s internal I/P (which moves the valve) can be seen with the HART communication protocol.
