MANOMETER PRESSURE SENSOR FOR USE IN HAZARDOUS CONDITIONS |
摘要 |
FIELD: physics, measurement. ^ SUBSTANCE: invention can be used to measure pressure in hazardous conditions. Methods and devices for manometer pressure perception using a manometer pressure sensor that comprises a casing and a manometer pressure sensing element including first pressure inlet and second pressure inlet. The first pressure inlet is connected to the atmospheric pressure. The second pressure inlet is connected to the inner section of the explosion-proof device with the help of fluid medium in the flame arrester placed in the sensor casing. ^ EFFECT: improving measurement accuracy. ^ 22 cl, 2 dwg |
