Fluke 710 mA Loop Valve Tester

Smart Control Valve Testing is now easier than ever

The Fluke 710 Valve Testing Loop Calibrator is designed to enable users to perform quick, easy tests on HART smart control valves. Featuring built-in test procedures and an intuitive user interface, the 710 allows users to quickly and easily perform valve tests, while the valve test quick-check results provide at-a-glance diagnostics help you make maintenance decisions faster than ever. The valve health quick-check results let you know whether your valve is in good, marginal or in bad operating condition so you can quickly decide whether additional maintenance is necessary.

Valve testing and HART communication in a precision loop calibrator

With the 710 Valve Testing Loop Calibrator’s built in HART communication function, users 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 determined through the HART communication protocol.

The 710 has built-in test procedures that automatically increase and change the mA signal while monitoring the HART position and pressure feedback from the control valve, giving you a better overall picture of valve health at the simple push of a button.

Pre-configured valve tests, at-a-glance answers

Valve test routines built into the 710 include:

  • Manual testing; manually change the mA signal and view the HART position and pressure variable information
  • Full range ramping of the mA signal from 4 to 20 to 4 mA while recording the 0-100-0% position, or the pressures applied that move the valve from 0-100-0%
  • Stepping the mA signal on the input to the valve in steps and evaluating the valves response to the mA input changes
  • Speed tests to determine how fast the valve can open or close
  • Bump and partial stroke tests that help test valves over a portion of their range so they can be tested in a live process

Fluke 725Ex Series

Process Calibrator

Fluke 725Ex provides an intrinsically safe, simple and powerful multifunction calibration solution

The 725Ex is an intrinsically safe multifunction process calibrator for use in explosion endangered areas. It is powerful, yet easy to use. Combine the 725EX with any of the eight Fluke 750PEx Pressure Modules (sold separately), and you’ll be able to calibrate almost any process instrument likely to need service in an area where explosive gasses may be present.

The 725EX sources and measures almost all process parameters including mA, volts, temperature (RTDs and thermocouples), frequency, ohms, and pressure, using optional pressure modules. Its split display lets you view input and output values simultaneously to calibrate transmitters. For valve and I/P tests, you can source mA while measuring pressure. The 725Ex has auto-stepping and auto-ramping for remote testing, plus 25% stepping for fast linearity tests.

From the moment you pick it up, the Fluke 725Ex is ready to perform. Its simple controls, without menus, make operation easy. Its memory functions make set up fast. And its rugged design lets it work as hard as you do.

Key features

  • Intrinsically safe multifunction process calibrator
  • Meets I.S. Class I, Division 1 Groups B-D, 171°C compliance standards
  • Measures volts DC, mA, RTDs, thermocouples, frequency, and ohms
  • Sources or simulates volts DC, mA, RTDs, thermocouples, frequency and ohms
