為何壓力開關輸出的電流不穩定
壓力開關的系列與類型繁多，而且都應用在各個行業中，但是在正常使用過程中，如果出現了電流忽高忽低的情況，是什么原因呢?
1.查看壓力開關供電電源是否是穩定的電源，如果供電電源本身不穩定，便是引起壓力開關電流輸出不穩定的最基本因素。
2.電流輸出不穩定，最直接的應該查看壓力開關的線纜是否有問題，是不是線纜因長期使用而產生了老化跡象，如果確實是線纜老化，那就要重新更換線纜；另外再檢查線纜是否接觸良好，接觸不良引起電流輸出不穩定也是經常發生的情況。
3.最后查看電流的不穩定是不是有規律的不穩定，最終輸出的信號和實際值是否一致，如果不一致，那就是壓力開關內部元件的問題了。
