The pressure gauge calibrator is standard equipment, which plays a key role in the smooth operation of the equipment of the production enterprise. Pressure gauge calibrators are mainly used in petroleum, chemical, natural gas refining, machinery, electricity, food processing and wine manufacturing. Pressure gauge calibrators are divided into single-range pressure calibrators, multi-range pressure calibrators, and portable pressure calibrators.

 1. Measurement accuracy level

 According to the accuracy level, it is divided into level 0.02, level 0.05 and level 0.1. The user should choose according to the accuracy level of the equipment used on site.

 2. Measuring range

 The measurement range of the field device determines the pressure gauge calibrator of the range that the user needs to select. The range of the pressure gauge calibrator should be determined according to the measurement range and accuracy level of the field equipment. If the budget is sufficient, you can choose a pressure gauge calibrator with a range corresponding to the field equipment.

 3. Will it bring stressors?

 There is no need to disassemble the field equipment, the user must calibrate the field equipment. In this case, it is more appropriate to choose a pressure corrector and a pressure factor overall device.

 4. Temperature range

 When selecting a pressure gauge calibrator, the user should consider the verification environment and verification conditions of the field equipment. If there is no standard laboratory, when choosing a pressure gauge calibrator, you must consider whether the pressure gauge calibrator performs temperature compensation. The temperature compensation range is 0-50 degrees, which is fully in line with the verification of various conditions on site.

 5. Device interface

 The user selects the pressure calibrator interface according to the on-site equipment (pressure source), which is generally M20*1.5 in China and 1/2NPT or 1/4NPT in foreign countries.

 6. Verify the software

 The user must record the verification of the field device in order to track the operation of the field device later, so you can consider choosing verification software.

 7. Other

 If most of the user's field devices are HART protocol pressure transmitter products, you can consider choosing a pressure gauge calibrator with HART function. This can directly verify the HART pressure transmitter, the economical pressure transmitter.
