   三、工作原理Working Principle

     變送器由傳感器與電子元件線路組成，被測(cè)介質(zhì)的壓力直接作用于傳感器的陶瓷膜片上，使膜片產(chǎn)生與介質(zhì)壓力成正比的微小位移，正常工作狀態(tài)下，膜片位移不大于0.025mm，電子線路檢測(cè)這一位移量后，即把這一位移量轉(zhuǎn)換成對(duì)應(yīng)于這一壓力的標(biāo)準(zhǔn)工業(yè)測(cè)量信號(hào)（4~20）mA。超壓時(shí)膜片直接貼到堅(jiān)固的陶瓷基體上，由于膜片與基體的間隙只有0.1mm，過(guò)載時(shí)膜片的位移只能是0.1mm，所以從結(jié)構(gòu)上保證了膜片不會(huì)產(chǎn)生過(guò)大變形。由于膜片采用高性能的工業(yè)陶瓷，因而使傳感器具有很強(qiáng)的抗沖擊及抗過(guò)載能力。
    Transmitter is composed of sensor and electronic element circuit, pressure of measured medium directly applies on sensor s ceramic diaphragm, force diaphragm to displace tinily in proportion to pressure of medium, under normal working condition, diaphragm displace no more than 0.025mm, electronic circuit detects this displacement, and convert it into standard industrial measuring signal i.e. (4～20mA) corresponding to this pressure. When overpressure, diaphragm directly stick to solid ceramic base body, as there is only 0.1mm gap between diaphragm and base body, when overpressure, the maximum diaphragm displacement could be no more than 0.1mm, (at that time, measuring diaphragm sticks to ceramic bracket, avoid damage) so structurally prevent diaphragm from excessive deformation. Because diaphragm adopts high functional industrial ceramic, sensor is significantly shock-proof and overload-proof.
