美國GE 氧傳感器OX-1 PPM O2 SENSOR

美國GE公司氧傳感器應用：1.用非危險性的低氧含量氣體（例如：高純氮氣）吹掃取樣系統。在正常工作時，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，編程和校準的步驟。然后，調整4-20mA模擬輸出，并將測氧的量程范圍設置到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，進行下一步。4.調整傳感器，讓它的金層電極對準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.此時對新傳感器進行空氣校準。在0-25%的氧量程范圍時，正確的傳感器校準會使變送器4-20mA的模擬輸出端輸出17.4mA的電流。6.用滾花螺母將校準過的傳感器封裝在變送器的測試頭內，調整好變送器的位置，用手擰緊滾花螺母。7.模擬輸出的讀數應該開始下降，平衡時會達到較低的氧含量。此時，重新設置需要的量程范圍。8.為O2X1供電。O2X1經過大約15秒鐘的初始化后，三個LED指示燈會同時短時間地亮起。為了提高PPM傳感器的測量精度，現在可以進行量程氣校準。
