The classification of the pressure gauge

Pressure gauge in English: pressure the gauge pressure and temperature are important process parameters in industrial production. If the pressure does not conform to the requirements, not only affects the production efficiency, reduce the quality of our products and can even cause serious accidents. So the pressure measurement has a special position in the industrial production. The classification of the pressure gauge pressure gauge is a lot of more phyletic, it not only has the general ( Ordinary) Pointer type indicator, and digital type; Not only has a regular pattern, and special type; Not only have a contact, and remote transmission; Not only has resistance to vibration mode, and resistant; Not only have the diaphragm, and corrosion resistance, etc. According to the measurement accuracy classification can be divided into precision pressure gauge, pressure gauge general pressure gauge. Precision pressure gauge measuring accuracy grades respectively 0. 1, 0. 16, 0. 25, 0. Level 4; General pressure gauge measuring accuracy level 1 respectively. 0 and 1. 6, 2. 5, 4. Level 0. According to gauge indicates the pressure gauge benchmark classification according to its indicated pressure benchmark is different, divided into general pressure gauge, absolute pressure gauge, differential pressure tables. General pressure gauge based on the atmospheric pressure; Absolute pressure table based on absolute pressure zero; Differential pressure table measurement measured pressure difference between the two.

according to the classification of pressure gauge measuring range is divided into vacuum gauge, pressure vacuum gauge, micro pressure table, low pressure table, medium voltage table and high pressure table. Vacuum gauge for measuring the pressure value is less than the atmospheric pressure; Pressure vacuum gauge for measuring the pressure value is less than and greater than atmospheric pressure; Micro pressure table is used to measure the pressure value of less than 60000 pa. The low pressure table used for measuring the 0 ~ 6 mpa pressure value; Medium voltage table used for measuring 10 to 60 mpa pressure value; High pressure table is used for measuring more than 100 mpa pressure value.

according to pressure gauge pressure gauge display mode classification according to the display mode can be divided into needle gauge and digital pressure gauge.

seismic pressure gauge made fully sealed structure, seismic pressure gauge of the shell and filling damping oil inside the shell, because of its vibration damping effect can be used in the work environment or medium pressure ( Load) Pulse measurement sites.

electric contact pressure gauge with electric contact pressure gauge control switch, can realize transmission alarm or control functions.

remote pressure gauge pressure gauge with remote transmission mechanism, can provide the electrical signals needed in industrial engineering ( Resistance signal or standard dc current signal, for example) 。

the diaphragm pressure gauge isolator (used by diaphragm table The chemical seal) Can pass isolation diaphragm, will from the instrument measured medium, in order to measure the strong corrosion, high temperature, easy to crystallization medium pressure. Memory type pressure gauge when measured element effect, black pressure display pointer will drive the red memory pointer to indicate, when there is no pressure to force, pressure display pointer will return to zero, black and red memory pointer will stay just shows the location of the pressure, let staff clearly know the work pressure display of, have the effect of a memory.
