   工作原理workingprinciple

   變送器由傳感器與電子元件線路組成，被測介質(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(zhuǎn)換成對應(yīng)這一壓力的標(biāo)準(zhǔn)工業(yè)測量信號即（4～20ma）。
    transmitter is composed of sensor and electronicelement circuit, pressure of measured medium directly applies onsensor s ceramic diaphragm, force diaphragm to displace tinily inproportion to pressure of medium, under normal working condition,diaphragm displace no more than 0.025mm, electronic circuit detectsthis displacement, and convert it into standard industrialmeasuring signal i.e. (4~20ma) corresponding to thispressure.

   超壓時膜片直接貼到堅(jiān)固的陶瓷基體上，由于膜片與基體的間隙只有0.1mm，過載時膜片的Zui大位移只能是0.1mm，(此時測量膜片貼到陶瓷支架上，避免損壞)所以從結(jié)構(gòu)上保證了膜片不會產(chǎn)生過大變形。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)的抗沖擊及抗過載能力。從襯底電極①和膜片電極②之間可以檢測到與壓力成比例的電容變化量，電容的變化值經(jīng)激光微調(diào)電路放大輸出高達(dá)0.5-4.5v的直流電壓，計(jì)算機(jī)可直接采樣。

    when overpressure,diaphragm directly stick to solid ceramic base body, as there isonly 0.1mm gap between diaphragm and base body, when overpressure,the maximum diaphragm displacement could be no more than 0.1mm, (atthat time, measuring diaphragm sticks to ceramic bracket, avoiddamage) so structurally prevent diaphragm from excessivedeformation. because diaphragm adopts high functional industrialceramic, sensor is significantly shock-proof and overload-proof.from between lining electrode① and diaphragm electrode②capacitancevariant in proportion to pressure can be detected, capacitancevariant value is amplified by laser micro adjustment circuit tooutput direct voltage as high as 0.5-4.5v, computer can sample itdirectly.

   變送器出廠前已根據(jù)用戶需求，量程、精度均已調(diào)到精度范圍以內(nèi)，一般不需校驗(yàn)。但以下情況需重新校驗(yàn)：
    before delivery transmitter has been set range,accuracy within accuracy range as per customer s request, normallydoesn t need calibration but as a exception if following situationsoccur：

    a.運(yùn)輸途中出現(xiàn)跌落、強(qiáng)烈震顛和碰撞；
       falling down, strongshock and vibration in transit；
    b. 存放期超過一年；
       over 1 year storage

    c.長時間運(yùn)行后，出現(xiàn)大于精度范圍內(nèi)的誤差；

   如何選擇壓力變送器（具體訂貨時參考）
   how tochoose pressure transmitter（refer to when ordering）
    (1) 確定測量介質(zhì)decide measuring medium
       根據(jù)腐蝕程度的大小選擇相應(yīng)的變送器，一般來說非強(qiáng)酸、強(qiáng)堿均可使用以不銹鋼為隔離單元的變送器，否則只能選擇專為防腐蝕設(shè)計(jì)的鈦合金等特制變送器。其次還需看測量介質(zhì)是否粘稠度，干凈程度，如果粘稠介質(zhì)就需要選擇硬性隔離單元的變送器。
    choose corresponding transmitter accordingto corrosivity, normally transmitter with stainless steel isolationcell is enough for non strong acid strong alkali, otherwise specialchemical seal product made in titanium alloy specially designed forcorrosion-proof must be used. secondly, need to know viscosity ofmeasuring medium, cleanliness, in case of very viscous transmitterof rigid isolation cell needs to be used.
    (2) 確定測量范圍和測量方式

        decide measuringrange and method
    一般選擇測量范圍時要考慮實(shí)際測量范圍，過壓測量范圍，選擇量程以Zui大測量范圍為準(zhǔn)，同時考慮過壓測量范圍的大小。另外需要選擇正確的測量方式，如果測量差壓必須選擇差壓變送器。
    normally when choosing measuring range, need toconsider actual measuring range, overpressure measuring range,choosing range should refer to the biggest measuring range,meanwhile consider volume of overpressure range. in addition, needto choose correct measuring method, if measuring pressuredifference, need to use differential pressure transmitter
    (3) 確定精度范圍，補(bǔ)償溫度范圍，使用溫度范圍

     decideaccuracy range, compensation temperature range, using temperaturerange.
    根據(jù)需要測量的Zui低精度，一般選擇略高于所要求Zui低精度的產(chǎn)品。 選擇時還需考慮長期穩(wěn)定性指標(biāo)。所謂補(bǔ)償溫度范圍即正常工作時測量介質(zhì)的溫度范圍，使用溫度范圍即使用過程中可能出現(xiàn)的Zui大溫度范圍，一般選擇時略大于測量介質(zhì)的溫度范圍。
    according to minimum accuracy, normally choose abit higher accuracy meanwhile when choosing, need to consider longterm stability compensation temperature range is that measuringmedium s temperature range when working normally, using temperaturerange is the biggest temperature range when using, normally choosea little bigger temperature range than re
    (4) 確定供電電源、輸出信號、壓力螺紋接口、電氣接口、機(jī)械尺寸等
        decide pressureconnection, electric connection, mechanical dimensions etc
    (5) 確定是否需要防爆，需要防電磁干擾，以及外殼防水的環(huán)境指標(biāo)
