The measurement range, accuracy level, and working environment requirements of a pressure gauge depend on the specific type and application scenario of the pressure gauge. Generally speaking, the measurement range of a pressure gauge is usually between tens to thousands of pascals (kPa) or several to hundreds of megapascals (MPa). Pressure gauges with different ranges can be selected according to actual needs.
Regarding accuracy levels, pressure gauges are usually classified into different grades based on their accuracy and error range, such as 0.5 grade, 1 grade, 1.5 grade, etc. Choosing the accuracy level that suits your requirements can ensure the accuracy of the measurement results.
As for the requirements for the work environment, the following points should be noted when using a pressure gauge:
Temperature range: The pressure gauge should have the ability to adapt to the temperature range of the working environment to ensure its normal operation and accurate measurement.
Pressure medium: Ensure that the pressure gauge is suitable for the measured medium, such as liquid, gas, or gas-solid two-phase media.
Protection level: Select pressure gauges with appropriate protection levels according to the needs of the working environment to prevent them from being affected by external environments such as dust and moisture.
Vibration and shock: For places with harsh working environments, it is necessary to choose pressure gauges that can withstand shock and impact to ensure their normal operation and service life.
Generally speaking, the measurement range, accuracy level, and working environment requirements of a pressure gauge are important factors to consider when selecting and using a pressure gauge. I hope this information is helpful to you. If you have any other questions, please feel free to let me know! If more specific information is needed, the specific model or application scenario of the pressure gauge can also be provided.
