傳感器的電路能夠保證應變電橋電路的供電，并將應變電橋的失衡信號轉換為統(tǒng)一的電信號輸出（0-5，4-20mA或0-5V）。在絕壓壓力傳感器和壓力變送器中，藍寶石薄片，與陶瓷基極玻璃焊料連接在一起，起到了彈性元件的作用，將被測壓力轉換為應變片形變，從而達到壓力測量的目的。 </p> <p> 5、壓電壓力傳感器原理與應用 </p> <p> 壓電傳感器中主要使用的壓電材料包括有石英、酒石酸鉀鈉和磷酸二氫胺。其中石英（二氧化硅）是一種天然晶體，壓電效應就是在這種晶體中發(fā)現(xiàn)的，在一定的溫度范圍之內，壓電性質一直存在，但溫度超過這個范圍之后，壓電性質完全消失（這個高溫就是所謂的“居里點”）。由于隨著應力的變化電場變化微?。ㄒ簿驼f壓電系數(shù)比較低），所以石英逐漸被其他的壓電晶體所替代。而酒石酸鉀鈉具有很大的壓電靈敏度和壓電系數(shù)，但是它只能在室溫和濕度比較低的環(huán)境下才能夠應用。磷酸二氫胺屬于人造晶體，能夠承受高溫和相當高的濕度，所以已經得到了***的應用。浙江轉速變送器量大從優(yōu)利用電磁感應的高頻振蕩型，使用磁鐵的磁力型和利用電容變化的電容型。</p><div

<p> （1）溫度變送器的操作： </p> <p> 1）運行：按子端接線圖檢查信號線連接是否正確→接通變送器的電源 </p> <p> 2）停運：關閉變送器供電電源 </p> <p> （2）變送器的日常維護 </p> <p> 1）通電情況下，嚴禁打開電子單元蓋和端子蓋，允許進行外觀檢查：檢查變送器，配管配線的腐蝕、損壞程度以及其它機械結構件的檢查。 </p> <p> 2）零點和滿度調整：禁止在現(xiàn)場打開端子蓋和視窗，只許在控制室內用手持通訊器進行調整。 </p> <p> 3）擱爆變送器的修理必須斷電后在安全場所進行。 </p><p> 轉速變送器 </p> <p> ZH1251A系列轉速變送器具有：轉速監(jiān)測、雙報警設置點、模擬電流輸出等功能。適用于電力、石油、化工等工業(yè)部門旋轉機械轉速的監(jiān)控和保護，如汽輪機、風機、壓縮機、電機、泵等。振動速度傳感器是利用磁電感應原理把振動信號轉換成電信號。它主要由磁路系統(tǒng)、線圈組件、彈簧阻尼等部分組成。在傳感器殼體中剛性地固定有兩個線圈組件，磁鋼用彈簧懸掛于殼體。當傳感器在工作頻率范圍內工作時，線圈與磁鋼產生相對運動，線圈切割磁力線，產生感應電動勢（感應電壓），該電壓正比于機殼的振動速度。適應惡力工業(yè)環(huán)境，有各種通用貨特種連接器，多種安裝螺紋或安裝法蘭。</p><div
