UKAS & BSI
A vacuum gauge is basically another type of pressure gauge, but it is used specifically for measuring pressure in a vacuum and therefore lower than standard atmospheric pressure. Vacuum pressure is zero-referenced against standard atmospheric pressure and is essentially the difference between absolute pressure and atmospheric pressure. This pressure value can be reported as a negative, but this is sometimes omitted for the purposes of reporting pressure measurements in a vacuum.
A wide selection of industries makes use of vacuums, such as pick and place surface mount technology in the automotive industry, food & beverage, manufacturing, pharmaceutical, chemical, nautical, etc. Vacuum gauges attached these systems are a key component in monitoring and maintenance of these systems on a regular basis.
Vacuum gauges are no different from standard pressure gauges in their operation in that they make use of a bended “Bourdon Tube” which deflects when it comes under pressure. This deflection is the converted by a mechanism within the gauge to position the needle at a specific pressure value.
In terms of calibration, Calibrationhouse uses BS EN 837-3:1998 - Pressure gauges as the cornerstone standard for all pressure and vacuum gauge calibration tests. We are able to offer our service either onsite at customers premises or via our laboratory rapid turnaround option and UKAS level testing is available on certain parameters.
