Pressure gauges are instruments that use elastic components as sensitive components to measure and indicate above ambient pressure. Applications are extremely common and are found in virtually all industrial processes and research areas. In the field of heat pipe network, oil and gas transmission, water supply and gas supply system, vehicle maintenance and repair shop, etc. can be seen everywhere. Especially in the process of industrial process control and technical measurement, mechanical pressure gauges are more and more widely used due to the high mechanical strength and convenient production of elastic sensitive components of mechanical pressure gauges.
Pressure gauge according to its measurement accuracy: can be divided into precision pressure gauges, general pressure gauges. The precision of the precision pressure gauges is 0.1, 0.16, 0.25, and 0.4, respectively. The accuracy of the general pressure gauges is 1.0, 1.6, 2.5, and 4. 0.
The pressure gauge is based on its measurement standard: the pressure gauge is divided into a general pressure gauge, an absolute pressure gauge stainless steel pressure gauge, and a differential pressure gauge according to the reference of the indicated pressure. The general pressure gauge is based on atmospheric pressure; the absolute pressure gauge is based on the absolute pressure zero; the differential pressure gauge measures the difference between the two measured pressures.
The pressure gauge according to its measurement range: 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 atmospheric pressure; the pressure vacuum gauge is used to measure the pressure value less than and greater than the atmospheric pressure; the micro pressure gauge is used to measure the pressure value less than 60000 Pa; the low pressure gauge is used to measure the pressure value of 0-6 MPa Medium pressure gauge is used to measure the pressure value of 10~60MPa;
The pressure gauge is displayed according to its mode: it is divided into a pointer pressure gauge and a digital pressure gauge.
The pressure gauge is divided according to its function: the pressure gauge can be divided into the local indication type pressure gauge and the charged signal control type pressure gauge according to the different functions of the pressure gauge.
