What are the different types of pressure calibrators?
Various kinds of pressure calibrators are used in different environments. Among all types, multifunction calibrators and deadweight testers are the most popular.
Handheld models are also available. The configuration, accuracy, and sensitivity of pressure often vary. High-end deadweight testers are equipped with highly precise sensors, which give a more accurate reading.
What factors should you keep in mind when choosing a pressure calibrator?
It is important to keep a few factors in mind to make sure you buy the right pressure calibrator.
- Pressure Range: Pressure range is the most important consideration. Handheld units, for instance, have a much lower range than deadweight testers, which are bulky and can’t be moved. Most models are capable of calibrating the pressure from -15 psi to 75,000+ psi. Custom pressure calibrators, which are designed for specific applications, are also available.
- Size: Pressure calibrators are available in a variety of sizes. If you are to take your pressure calibrator to the field, it would be a good idea to choose a portable unit. However, if you will be using it in the facility, a bulkier, deadweight tester might be a good choice.
How much does a pressure calibrator cost?
Pressure calibrators are available at different price points. Its price depends on many features, such as pressure range, type, brand, and accuracy. Some models retail for a higher price, especially those equipped with high-precision sensors.
Which components of a pressure calibrator need the most attention?
Just like every other piece of machinery, some components of the pressure calibrator require your attention more than others. These components include:
- Display: pressure calibrators feature a display to show the readings. The display can sustain damage, and care must be taken to prevent knocks and bumps.
- Pump: The pressure pump plays an important role in the calibration process, as it generates the pressure. It needs to be properly maintained, including checking the mechanical seal and regularly cleaning the unit.
What are the typical applications of a pressure calibrator?
A pressure calibrator is used in industries and research facilities to determine the accuracy of any device that includes a pressure gauge. They are used in laboratories, the automotive industry and manufacturing.
What are common problems with a pressure calibrator?
- Failing Pressure Pump: If the pressure pump is faulty, it won’t create any pressure. This can happen due to the mechanical seal sustaining damage, or a problem with the internal components.
- Leakage: This problem usually arises when the connections are not sealed. It could prevent the pressure calibrator from working properly.
Do I need any certifications or training to operate a pressure calibrator?
Some level of training is required for users to understand how to read and interpret the output signal from the sensor. Other licences or certifications might be required depending on the industry where it’s being used.
