隔膜在被測介質(zhì)壓力作用下產(chǎn)生變形,密封液被壓,形成一個(gè)相當(dāng)于P的壓力,傳導(dǎo)至壓力儀表,顯示被測介質(zhì)壓力值。
溫度影響：
因密封液的熱膨脹及隔膜剛度與溫度有關(guān)，在使用溫度偏離20℃±5℃時(shí)，受溫度影響有一個(gè)誤差，其值為0.1%/℃。

Divide in measured media deformation under pressure, was sealed by pressure to form a pressure equivalent to the P, conduction to pressure instruments that measured media pressure value. 
Temperature effects: 
Sealed because of the lack of stiffness and thermal expansion and temperature, the use of temperature from 20 ℃ ± 5 ℃, the temperature impact on a error, its value is 0.1% / ℃.

Hose connected to divide the installation of pressure gauges, and if the pressure of the pressure on the instrument in different locations, its level will create a pressure differential △ P bad influence, △ P = sealed the proportion of poor X Level

Divide the corrosion resistance of pressure gauges includes the environment and the corrosion of media measurement, matching conditions can be isolated, divide, sealing gasket material.
