Sealing gasket material: Dingqing rubber, plastic fluoride. Seal of: silicone oil, vegetable oil,. Implementation of the standards: JB/T8624-1997 | 结构原理: | 隔膜在被测介质压力作用下产生变形,密封液被压,形成一个相当于P的压力,传导至压力仪表,显示被测介质压力值。 温度影响: 因密封液的热膨胀及隔膜刚度与温度有关,在使用温度偏离20℃±5℃时,受温度影响有一个误差,其值为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% / ℃. | 液位差: | 软管连接的隔膜压力表在安装时若受压部与压力仪表处不同位置,其液位差将形成一个压力差△P的影响,△P=密封液比重X液位差 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 | 耐蚀性: | 隔膜压力表的耐蚀性能包含环境及测量介质的腐蚀特性,可按使用条件选配隔离器,隔膜,密封垫圈的材料。 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. | |
