Y-M系列隔膜壓力表
|
隔膜壓力表采用間接測量結(jié)構(gòu)，適用于測量粘度大、易結(jié)晶、腐蝕性大、溫度較高的液體、氣體或顆粒狀固體介質(zhì)的壓力。隔離膜片有多種材料，以適應(yīng)各種不同腐蝕性介質(zhì)。
儀表適用于化學(xué)工業(yè)、化纖、合成纖維、石油、染化、制堿等工業(yè)。
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.

結(jié)構(gòu)原理：
|
|
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% / ℃.
|
|
液位差：
|
軟管連接的隔膜壓力表在安裝時(shí)若受壓部與壓力儀表處不同位置，其液位差將形成一個(gè)壓力差△P的影響，△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
|
|
耐蝕性：
|
隔膜壓力表的耐蝕性能包含環(huán)境及測量介質(zhì)的腐蝕特性，可按使用條件選配隔離器，隔膜，密封墊圈的材料。
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.
