Y-M系列隔膜压力表
|
隔膜压力表采用间接测量结构，适用于测量粘度大、易结晶、腐蚀性大、温度较高的液体、气体或颗粒状固体介质的压力。隔离膜片有多种材料，以适应各种不同腐蚀性介质。
仪表适用于化学工业、化纤、合成纤维、石油、染化、制碱等工业。
Divide by indirect measurement of pressure gauges, to measure the viscosity, easy to crystallization, corrosive, high temperature of the liquid, gas or granular solid media pressure. There are many isolated patch material to meet the various aggressive media.
Instrument applies to the chemical industry, chemical fiber, synthetic fiber, oil, dyeing, caustic soda production, and other industries.

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.
