Fluke 710 mA Loop Valve Tester
Testing intelligent control valves is now easier than ever
El calibrador de lazo para comprobación de válvulas Fluke 710 se ha diseñado para permitir que los usuarios realicen pruebas de forma rápida y fácil en válvulas inteligentes de control HART. El 710 ofrece procedimientos de comprobación integrados y una interfaz de usuario intuitiva que permite a los usuarios comprobar las válvulas de forma rápida y fácil. Además, los resultados de la comprobación rápida de las válvulas permiten realizar un diagnóstico de un simple vistazo para que pueda tomar decisiones de mantenimiento con más rapidez que nunca. Los resultados de la prueba rápida del estado de la válvula indican si el estado de funcionamiento de la válvula es bueno, reducido o malo, lo que le permitirá decidir rápidamente si es necesario realizar un mantenimiento adicional.
Valve testing and HART communication in a precision loop calibrator
Gracias a la función de comunicación HART, integrada en el calibrador de lazo de comprobación de válvulas 710, los usuarios pueden generar una señal de 4-20 mA para desplazar la válvula de control inteligente e interpretar la señal de información HART de la válvula para determinar si la válvula se está desplazando a la posición prevista. Además de información sobre la posición se puede determinar la presión medida que proporciona la I/P interna de la válvula (que desplaza la válvula) mediante el protocolo de comunicación HART. El 710 incorpora con procedimientos de comprobación que aumentan y cambian automáticamente la señal de mA y supervisan la información de presión y posición HART de la válvula de control, lo que le proporciona una mejor información general del estado de la válvula con solo pulsar un botón.
Preconfigured valve tests, responses at a glance
The valve test functions integrated into the 710 include:
- Manual test: manually change the mA signal and view variable information on HART position and pressure.
- Ramp function across the full mA signal range from 4 to 20 to 4 mA while recording the 0-100-0% position or the applied pressure moving the valve from 0-100-0%.
- Stepping the mA signal at the valve input in increments and evaluating the valve's response to changes in the mA input.
- Speed tests to determine how quickly the valve can open or close.
- Impact and partial stroke tests that help check valves over part of their range so they can be tested in real-time processes.
ValveTrack™ software enables post-analysis and trend generation
Las pruebas de la válvula que se registran y se guardan en la memoria del 710 pueden cargarse en el software de análisis ValveTrack™ (incluido). El software ValveTrack™ le permite:
- Load, print, and plot recorded valve tests performed in the field.
- Compare previously loaded tests with more recent ones.
- View valve test history with the HART identification tag.
- Export valve test data to CSV for further analysis in Microsoft Excel®.
Save time, get answers
Additionally, the 710 model offers:
- On-site HART data logging. Once recorded by the 710 model on-site, ValveTrack™ software can load the HART configuration of up to (20) HART devices in your plant and output data in (.csv) and (.txt) formats.
- Recorded mA loop measurements and HART data can be logged from a specific transmitter for troubleshooting and loop calibration. The data logging feature offers selectable capture intervals between 1 and 60 seconds and a logging capacity to store 4910 records or 99 individual sessions. Each record contains the mA measurement and the four process variables.

HART communication
The Fluke 710 includes an integrated HART modem to communicate the following HART commands:
- Read sensor PV information.
- Read output PV information.
- Read and write PV unit type, identification tag, description, and message.
- Read and write PV ranges (upper and lower).
- Enable/disable fixed current mode.
- Define zero offset.
- Zero adjustment of the D/A converter (output 4 mA).
- Gain adjustment of the D/A converter (output 20 mA).
HART commands for valves
The 710 model includes the following exclusive HART commands compatible with control valves:
- Automatic valve controller tuning
Additionally, the Fluke 710 device offers:
- On-site HART data logging. Once recorded by the 710 model on-site, ValveTrack™ software can load the HART configuration of up to (0) HART devices in your plant and output data in .csv or .txt format.
- mA loop measurements with data logging and HART data can be recorded from a specific transmitter for troubleshooting and loop adjustment. The data logging feature offers selectable capture intervals between 1 and 6 seconds and a logging capacity to store 4910 records or 99 individual sessions. Each record contains the mA measurement and the four process variables.
