   三、工作原理Working Principle

     變送器由傳感器與電子元件線路組成，被測介質的壓力直接作用于傳感器的陶瓷膜片上，使膜片產生與介質壓力成正比的微小位移，正常工作狀態下，膜片zui大位移不大于0.025mm，電子線路檢測這一位移量后，即把這一位移量轉換成對應于這一壓力的標準工業測量信號（4~20）mA。超壓時膜片直接貼到堅固的陶瓷基體上，由于膜片與基體的間隙只有0.1mm，過載時膜片的zui大位移只能是0.1mm，所以從結構上保證了膜片不會產生過大變形。由于膜片采用高性能的工業陶瓷，因而使傳感器具有很強的抗沖擊及抗過載能力。
    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.

       when measuring steam or other high temperature media, make sure transmitter s working temperature limit is observed. Fit cooler or other cooling device if necessary.
    5. 安裝時應在變送器和介質之間加裝壓力截止閥，以便檢修和防止取壓口堵塞而影響測量精度。在壓力波動范圍大的場合還應加裝阻尼器或壓力緩沖裝置。
    when mounting, shut valve should be used between transmitter and medium, for easy maintenance and to prevent pressure taking port from blocking that influences measuring accuracy. Damper or pressure buffer should be used where big pressure fluctuation exists.
