Oil cylinder manufacturer in Pressure gauge What are the categories?

Classification of pressure gauge: 1. According to its measurement, pressure gauge can be divided into precision pressure gauge and general pressure gauge. The measurement grade of precision pressure gauge is 0.1, 0.16, 0.25, 0.4 and 0.05 respectively; The measurement levels of general pressure gauges are 1.0, 1.6, 2.5 and 4 Level 0. 2. Pressure gauges are divided into general pressure gauges, pressure gauges, stainless steel pressure gauges and differential pressure gauges according to their different measuring standards. General pressure gauges are based on atmospheric pressure; The absolute pressure gauge is based on the pressure zero position; The differential pressure gauge measures the difference between the two measured pressures. 3. According to its measuring range, the pressure gauge is divided into vacuum gauge, pressure vacuum gauge, micro pressure gauge, low pressure gauge, medium pressure gauge and high pressure gauge. The vacuum gauge is used to measure the pressure value less than the atmospheric pressure; The pressure vacuum gauge is used to measure the pressure value less than or greater than the atmospheric pressure; The micro pressure gauge is used to measure the pressure less than 60000 Pa; Low pressure gauge is used to measure the pressure value of 0~6MPa; The middle pressure gauge is used to measure the pressure value of 10~60MPa; 4. The pressure gauge is divided into pointer pressure gauge and digital pressure gauge according to its display mode. 5. Pressure gauges can be divided into local indicating pressure gauges and live signal control pressure gauges according to their functions.
