Selection and Installation of Industrial Pressure Gauges

Ⅰ. The correct selection of industrial pressure gauges


The correct selection of industrial pressure gauges mainly includes determining the type of industrial pressure gauge, the range of the industrial pressure gauge, the range of the industrial pressure gauge, the accuracy of the industrial pressure gauge and the sensitivity of the industrial pressure gauge, the overall size of the industrial pressure gauge, and whether it needs to be far transmission and other functions, such as indication, recording, adjustment, alarm and so on.


Ⅱ. The main basis for the selection of industrial pressure gauges


Industrial pressure gauge selection and installation 1


The measurement requirements of the production process, including range and accuracy. In the case of static test (or slow change), it is stipulated that the maximum value of the measured pressure should be two-thirds of the full scale value of the pressure gauge; in the case of pulsating (fluctuating) pressure, the maximum value of the measured pressure shall be one-half of the full-scale value of the pressure gauge.


The accuracy grades of commonly used pressure detection instruments are 0.4, 1.0, 1.5 and 2.5, etc., which should be selected from the production process accuracy requirements and economic point of view. The maximum allowable error of an industrial pressure gauge is the product of the range of the instrument and the percentage of accuracy grade. If the error value exceeds the accuracy required by the process, it is necessary to replace a pressure gauge with a higher accuracy.


Industrial pressure gauge selection and installation 2


The properties of the measured medium, such as state (gas, liquid), temperature, viscosity, corrosiveness, degree of contamination, flammability and explosiveness, etc. Such as oxygen meter, acetylene meter, with "no oil" mark, dedicated to corrosion-resistant pressure gauges, high-temperature-resistant pressure gauges, diaphragm pressure gauges, etc. for special media.


Industrial pressure gauge selection and installation 3


Environmental conditions on site, such as ambient temperature, corrosion, vibration, humidity, etc. Such as shock-proof pressure gauges used for vibrating environmental conditions.


Industrial pressure gauge selection and installation 4


Suitable for observation by staff. Choose meters with different gauge diameters (outer dimensions) according to the location and lighting conditions of the detection meters.
