Vacuum Gauge Calibration

A vacuum gauge is a pressure gauge used to measure pressure in a vacuum. Different vacuum gauges are required, depending on the kind of vacuum system and the desired operating vacuum level, to properly determine and/or manage the vacuum level of the chamber at any given time, typically in combination with one another.

Vacuum gauges are fundamental measuring components found in vacuum lines or directly attached to the vacuum chamber in vacuum furnace systems and other applications. A vacuum gauge isa device for measuring pressures below atmospheric pressure. These gauges’ accuracy is fundamental. That is why their regular calibration is essential.

Vacuum Gauge CalibrationWhy is Vacuum Gauge Calibration important?

The first step in ensuring accuracy and repeatability in your process or application is to choose the proper vacuum gauge or leak standard. Calibration insures that your measurements are accurate and within the bounds of your specified specifications. Instrument calibration is in high demand  to satisfy the expectations of company quality systems. Process engineers know that accurate measurements are required to achieve consistent findings, which requires not just sturdy equipment and reference standards, but also calibrated ones.

Calibration Process

Gauge calibration establishes how much a measuring instrument's indication deviates from its genuine value. The calibration procedure' data can be utilized to alter the gauge. However, calibration goes beyond basic adjustments. A calibrated gauge can be traced back to a master source. Traceability adds value to the calibration procedure.

A qualified technician determines the gauge's accuracy by measuring a recognized standard master traceable to the N.I.S.T. or equivalent international organizations in the United States. Calibration is carried out by following a series of test protocols designed for specific devices. The goal is to complete the measuring operation under as close to perfect conditions as possible to ensure that the results reflect the gauge's accuracy and repeatability and are not controlled by external variables.

How Often Does Vacuum Gauge Need Calibration?

There are no guidelines or disciplines that specify how frequently measuring devices should be examined. The frequency of calibration is determined by usage and mistreatment.

Many quality control professionals believe that all measurement devices should be calibrated once a year. But the truth is the calibration should be done at regular intervals; the key term here is regular. Regular calibration has the advantage of providing a historical record of instrument performance. When calibrating an instrument, the calibration data should be compared to historical data to see if the calibration interval should be reduced or prolonged.

There are, though, some general criteria for calibration intervals. Calibration intervals should be calculated based on instrument manufacturer guidelines, stability, purpose, usage, and repeatability history. Recalibration should be done anytime an incident happens that causes the instrument's accuracy to be doubted.
