GC ELECTRONICS ML 1850改善應變式傳感器穩(wěn)定性方法探討
解決應變式傳感器零點輸出長期穩(wěn)定性的問題, 就必須解決傳感器制造工藝和整個傳感器制造過程中控制電阻材料的電阻率變化因素、基底膠和彈性體材料的應力狀態(tài)、幾何尺寸的變化問題。怎樣解決這些問題是具體的技術問題。在實際工程中，可以從以下方面改善應變式傳感器穩(wěn)定性。
4.1 應變片的粘貼
敏感元件是電阻應變式傳感器的重要組成部分,在實際測量中常選用應變片,因此應變片的粘貼成了關鍵技術之一。
      應變片粘貼注意分清應變片的正、反面(有引出線引出的一面為正面)，用左手捏住應變片的引線，右手上膠，在應變片的粘貼面(反面)上勻而薄地涂上一層粘結劑。待一分鐘后，當膠水發(fā)粘時，校正方向(應變片的定位線與十字線交叉線對準，其電阻柵的絲繞方向與十字線中較長線的方向一致，即保證電阻柵的中心與十字交叉點對準，再墊上塑料薄膜，用手沿一個方向滾壓1~2分鐘即可。見圖2。

 應變片粘貼完畢后的檢查：應變片貼好后，先檢查有無氣泡、翹曲、脫膠等現(xiàn)象，再用數字萬用表的電阻檔檢查應變片有無短路、斷路和阻值發(fā)生突變(因應變片粘貼不平整導致)的現(xiàn)象，如發(fā)生上述現(xiàn)象，就會影響測量的準確性，這時要重貼。
