Precision pressure gaugeMainly used for verifying industrial applicationsPressure gaugeIt can also be used for online measurement of the pressure of high-precision working media.
Precision pressure gaugeIt is a commonly used measuring standard in the fields of pressure measurement, testing, verification, and inspection of pressure parameters. The instrument, originally known as the standard pressure gauge, has a long production history in China and has a complete series and specifications. It complies with the national standard GB-1227 and the verification regulation JJG-49. Its simple structure, stable performance, intuitive indication, high cost-effectiveness, and complete series make it widely used in industries such as petroleum and chemical, production and scientific experiments, as well as in pressure value transmission and metrological verification departments at all levels.
Precision pressure gaugeAccuracy level: This instrument is a high-precision pressure measuring instrument with a spring tube as the measuring element. It belongs to the category of spring tube pressure gauges and is a high-precision standard spring tube pressure gauge. Its accuracy level is divided into 0.4 level, 0.25 level, 0.16 level, and 0.1 level. People often refer to instruments with 0.4 and 0.25 levels as high-precision pressure gauges, and instruments with 0.16 and 0.1 levels of accuracy as high-precision precision pressure gauges or high-precision pressure gauges.
Precision pressure gaugeClassification of measurement range:
1. Micro pressure gauge (refers to instruments with an upper limit measurement value less than 0.1MPa)
2. Low pressure gauge (refers to instruments with an upper measurement limit of 0.1MPa [including 0.1MPa] to 6MPa [including 6MPa])
3. Medium pressure gauge (refers to instruments with an upper limit measurement value between 10MPa [including 10MPa] and 60MPa [including 60MPa])
4. High pressure gauge (refers to instruments with an upper measurement limit greater than 60MPa to 160MPa [including 160MPa])
5. Ultra high pressure gauge (referring to instruments with an upper limit measurement value greater than 160MPa)
Precision pressure gauges can be classified into:
1.vacuum meter(Refers to instruments with negative pressure measurement range)
2.pressure gauge（Instruments with a positive pressure measurement range
3. Pressure vacuum gauge (referring to instruments with a range from negative pressure to positive pressure)
Precision pressure gauges can be divided into: 1. Direct installation type (often referred to as their base type instrument, i.e. radial joint direct installation type) according to their installation structure
2. Convex installation type (referring to instruments with mounting rings or edges at the rear)
3. Embedded type (Embedded type is divided into axial embedded type and radial embedded type, often referred to as axial forward edge and radial forward edge instruments)
