Pressure gauge according to their measurement accuracy: can be divided into precision pressure gauge, general pressure gauge. Accuracy of precision pressure gauges were 0.1,0.16,0.25,0.4 class 0.05 level; general pressure gauges of the measurement accuracy grade 1.0,1.6,2.5,4. 0 level.
Gauge according to their measurement standards: Gauge pressure gauge according to their different instructions, divided into general pressure gauge, absolute pressure gauge stainless steel pressure gauge, differential pressure gauge. General pressure gauge to atmospheric pressure as a benchmark; absolute pressure gauge absolute zero as a benchmark; differential pressure gauge to measure the difference between the two measured pressure.
Pressure gauge according to their measuring range: divided into vacuum gauge, pressure vacuum gauge, micro pressure gauge, low pressure gauge, pressure gauge and high pressure gauge. Vacuum gauge is used to measure pressure values less than atmospheric pressure; pressure vacuum gauge is used to measure pressure values less than and greater than atmospheric pressure; micro-pressure gauge is used to measure pressure values less than 60,000 Pa; low pressure gauge is used to measure pressure values 0-6 MPa ; Pressure gauge used to measure the pressure value of 10 ~ 60MPa; |
