美國GE公司氧傳感器應(yīng)用：1.用非危險(xiǎn)性的低氧含量氣體（例如：高純氮?dú)猓┐祾呷酉到y(tǒng)。在正常工作時(shí)，要求通入傳感器測試頭的氣體為500cc/min（1.0SCFH），壓力為大氣壓。持續(xù)通入該氣體，直到完成傳感器的安裝。2.在安裝前，編程和校準(zhǔn)的步驟。然后，調(diào)整4-20mA模擬輸出，并將測氧的量程范圍設(shè)置到0-25%O2。3.打開密封盒，取出氧傳感器。為了保持氧傳感器的能量，立即除去紅色貼片，進(jìn)行下一步。4.調(diào)整傳感器，讓它的金層電極對準(zhǔn)變送器的底座上具有彈性的接觸管腳。用手將傳感器緊緊壓在O2X1變送器上。5.此時(shí)對新傳感器進(jìn)行空氣校準(zhǔn)。在0-25%的氧量程范圍時(shí)，正確的傳感器校準(zhǔn)會(huì)使變送器4-20mA的模擬輸出端輸出17.4mA的電流。6.用滾花螺母將校準(zhǔn)過的傳感器封裝在變送器的測試頭內(nèi)，調(diào)整好變送器的位置，用手?jǐn)Q緊滾花螺母。7.模擬輸出的讀數(shù)應(yīng)該開始下降，平衡時(shí)會(huì)達(dá)到較低的氧含量。此時(shí)，重新設(shè)置需要的量程范圍。8.為O2X1供電。O2X1經(jīng)過大約15秒鐘的初始化后，三個(gè)LED指示燈會(huì)同時(shí)短時(shí)間地亮起。為了提高PPM傳感器的測量精度，現(xiàn)在可以進(jìn)行量程氣校準(zhǔn)。
