Calibración
Calibration helps ensure accurate measurements that are foundational to the quality and safety of our everyday lives. As a calibration professional, the world relies on you to get it right. And, we’re here to help you get it right with educational articles on various calibration topics including new testing and calibration processes, custody transfer, sensor and transmitter calibration, calibration in the field and at the bench, and much more. (See also our Fluke Calibration blog.) We’re also intent on helping your do your job right with the best calibrators. Check out our recommended calibrators in the area of your need: temperature, pressure, multifunction, mA loop, benchtop and standards.

Learn how to avoid calibration drift on control valve positioners as part of your preventive maintenance program.
Pairing a Fluke dry well with a handheld documenting calibrator allows for a complete field temperature sensor calibration solution.
How to perform a verification test on analog vs digital pressure gauges. Both analog and digital process gauges need to be verified to detect errors related to drift, environment, electrical supply, addition of components to the output loop, and other process changes
La calibración precisa de los presostatos es un componente fundamental para garantizar la calidad del proceso y el funcionamiento seguro del equipo.
It's important to select the proper pump and gauge to match the testing application at hand—a good guideline is the testing device should be 4-10 times more accurate than the device being tested.
Gas custody transfer flow computers that calculate flow in pipelines by measuring the differential pressure across a flow restriction, such as an orifice plate or other differential pressure flow device, require special calibration to perform at optimum accuracy.
A pressure comparator is a convenient instrument for bench pressure calibration. Bench calibrations are performed to maintain reference conditions and to obtain the lowest possible uncertainties. The bench is also a convenient place to inspect, adjust, and repair the devices under test.
A deadweight tester is a proven method of pressure calibration that is usually chosen for bench applications when accuracy and reliability are the top requirements. Calibrations are performed at the bench for convenience and to maintain reference conditions.
Verifying and documenting the performance and adjusting a HART smart pressure transmitter can require a bucket full of tools. Performing this task with a HART enabled calibrator like the Fluke 754 simplifies the task and reduces what you need to carry.
En una planta de fabricación de componentes críticos para compañías aeroespaciales, un técnico calibra el sistema de control que mantiene temperaturas precisas dentro de los hornos que endurecen los componentes de metal durante los procesos de termotratado.
La calibración de la presión puede ser difícil en los mejores ambientes. Trabajar en un área que tiene el potencial de explosión lleva el grado de dificultad a otro nivel, uno en el que el técnico debe tener la capacitación y el equipo adecuados.
Al evaluar las válvulas de control y su desempeño, debe entender los diferentes tipos de válvulas y lo que se puede comprobar en ellas. Para válvulas de cierre abiertas/cerradas sin control análogo las pruebas son muy sencillas.
Las válvulas inteligentes de control proporcional realizan una labor fundamental en las industrias de procesos. No obstante, evaluar de forma precisa su rendimiento puede llegar a ser una de las tareas habituales más engorrosas ya que a menudo implica tiempos de inactividad considerables y desmontar las válvulas de la línea.
