Pressure Calibration Services: Different Types of Calibration
Pressure gauges are very commonplace throughout the worlds of research and manufacturing. As with any measuring instrument, a pressure gauge must be periodically assessed to ensure its accuracy and precision; sometimes, the gauge may also require some adjustments. This process is known as the calibration of equipment.
There’s more involved in pressure gauge calibration than you might think, including different types of calibration. LCS is a leading provider of pressure calibration services, and in this article, we’ll outline some of the complexities of calibrating pressure gauges.
What are the Different Types of Pressure?
To begin with, it’s important to understand that there are different kinds of pressure.
For example, when people talk about barometric pressure, they’re talking about the absolute pressure of the atmosphere.
And then there’s differential pressure, which denotes the difference between two separate pressures.
The most commonly measured type of pressure is gauge pressure. This simply refers to the difference between a measured pressure and the current atmospheric pressure.
By contrast, there is absolute pressure. This refers to the difference between a measured pressure and a vacuum.
Knowing the different kinds of pressure can be helpful as you learn more about the calibration of pressure gauges.
What are the Different Types of Gauges?
It’s also worth keeping in mind that pressure may be measured with different kinds of gauge.
The most common by far is the analog pressure gauge. These instruments consist of a pointer needle along with a pressure scale. There may also be a Bourdon tube and a mechanical apparatus, which moves the pointer across the scale as the pressure builds.
Digital pressure gauges, which use numeric indicators as opposed to analog pointers, also exist, but are less common in lab or industrial settings.
At LCS, we handle everything from temperature calibration services to electronics calibration services, so we know a thing or two about different types of instruments. Reach out to us directly if you have additional questions.
Other Key Points About Pressure Calibration
Here are a few additional notes about the calibration of equipment, and specifically pressure gauges.
- Different pressure gauges have different accuracy classes. It’s important to know the specific accuracy class of your instrument, as this will determine the acceptable accuracy range.
- In calibrating your pressure gauge, you need to know the medium. Instrument calibration services will ask you about the media of your pressure gauges; this basically just means whether you use it to measure liquid or gas.
- Calibration may require decontamination. Sometimes, dirt and debris can make their way inside the gauge. Not only does this compromise accuracy, but it also imperils the lifespan of your equipment.
- Leak tests may also be part of the process. Even the tiniest leak in your pressure gauge can interfere with results, and also impede the calibration process. As such, leak tests are an important part of testing and evaluation.
