Choosing the Best Pressure Calibrator for Your Needs

Choosing the Best Pressure Calibrator for Your Needs

There are many different types of pressure standards available for performing pressure calibrations. Finding the perfect solution for your pressure calibration can be overwhelming if you are still trying to figure out where to start. The key is to know what type of questions to ask when making your decision.


What is a Pressure Calibrator? 

A pressure calibrator is a pressure measuring device capable of calibrating the pressure reading of another measuring device. Sometimes they are also referred to as pressure standards. The pressure calibrator must be more accurate than the device being calibrated. The calibration ratio is 4:1. The pressure calibrator is four times more accurate than the device it calibrates.


Pressure Calibrator Types                                                  

Pressure calibrators come in a variety of configurations to fit specific requirements. For field pressure calibration, there is a need for portability and functions that may include voltage, amperage, or digital signal monitoring from the device being calibrated. In this case, handheld multifunction calibrators are the best choice.

When higher accuracy is required in a laboratory and precise control of pressure is needed, a pressure calibrator is the best choice.

The types of calibrators include:

  • Piston gauges
  • Deadweight testers
  • Pressure controllers and calibrators
  • Pressure comparators and digital pressure gauges
  • Handheld pressure calibrators


Questions to Ask When Deciding on A Pressure Calibrator

  1. What is the accuracy of the uncertainty of the device to be tested? Once you know the specifications of your device under test, you can look for calibrators that will give you what you need.
  2. Where will you be using the calibrator? If you are taking it to the field, your requirements will differ from using it in a laboratory.
  3. What are the device’s pressure range and test medium to be tested? Once you know which categories of instruments will meet your measurement uncertainty needs and operate in your environment, you can determine which model and classes can be used.
  4. Do you need to generate and control pressure?  Most calibration procedures require comparing the device under test and calibration standards at multiple pressure points across the range.
  5. What are the extras that you need to complete the solution? You’ll want to ensure you have the connection cords, protect the system from contamination, mounts if needed, and any maintenance extras.
  6. Will you need training? Check with the company you purchase from if they offer training on using or maintaining the equipment. Also, if they are ISO/IEC 17025 accredited, so when the pressure calibrator needs to be calibrated, they can handle it.
