隔膜式系列壓力表（配接化學(xué)密封），是由一個(gè)不同類(lèi)型的通用壓力表與一個(gè)隔膜隔離體配接而成的。
在通用型壓力表與隔膜隔離體之間還可以配接具有特定要求的連接體。通過(guò)這種配接，使一般通用型
的壓力表，增加了對(duì)特殊腐蝕要求、溫度高、粘度大或含有固態(tài)浮游物、易凝固介質(zhì)壓力的測(cè)量性能。
隔膜式壓力表（配接化學(xué)密封）在石油化工、制堿、化纖、制藥、鋼鐵、食品等行業(yè)測(cè)量流體介質(zhì)壓
力時(shí)被廣泛使用。
Series YTP diaphragm pressure gauge (chemical seals) is composed of a conventional pressure
measuring instrument, a connector and a diaphragm seal. This combination enables a general purpose
pressure gauge to measure media of strong corrosion, high temperature, high viscosity, containing
suspended matter or crystallizing.
Diaphragm gauges are universally used in petrochemical, alkali, chemical fiber, pharmaceutical,
metallurgical, and food industries.

配接化學(xué)密封系列壓力表的工作原理如圖所示。
隔離膜片在被測(cè)介質(zhì)壓力P的作用下產(chǎn)生變形，壓縮
內(nèi)部充填的工作液形成一個(gè)相當(dāng)于 P的壓力 P’。經(jīng)
工作液的傳導(dǎo)，使壓力儀表中的彈性元件自由端產(chǎn)生
相應(yīng)的變形，并按與之相配接的類(lèi)別壓力儀表工作原
理顯示出被測(cè)的壓力值。
Configuration Principle
This illustration shows the operating principle of the
diaphragm pressure gauge.
The diaphragm is deflected by the pressure of me-
dium P, and an equivalent pressure P’ is generated.
With transmitting through working fluid, the pressure
P’ deflect the elastic element of a pressure measur-
ing instrument which thereafter shows the pressure
value.
