   三、工作原理Working Principle

     变送器由传感器与电子元件线路组成，被测介质的压力直接作用于传感器的陶瓷膜片上，使膜片产生与介质压力成正比的微小位移，正常工作状态下，膜片位移不大于0.025mm，电子线路检测这一位移量后，即把这一位移量转换成对应于这一压力的标准工业测量信号（4~20）mA。超压时膜片直接贴到坚固的陶瓷基体上，由于膜片与基体的间隙只有0.1mm，过载时膜片的位移只能是0.1mm，所以从结构上保证了膜片不会产生过大变形。由于膜片采用高性能的工业陶瓷，因而使传感器具有很强的抗冲击及抗过载能力。
    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.
