電子壓力開關靈敏度的選擇
電子壓力開關是一款不論是從外觀結構還是使用性能方面都比機械壓力開關優越的智能化開關，因此，電子壓力開關的靈敏度也自然比其高，下面小編介紹如何選擇電子壓力開關的靈敏度。
通常，在開關的線性范圍內，都是希望開關的靈敏度越高越好。因為只有靈敏度高時，與被測量變化對應的輸出信號的值才比較大，有利于信號處理。但要注意的是，當電子壓力開關的靈敏度高，與被測量無關的外界噪聲也容易混入，也會被放大系統放大，影響測量精度。因此，要求壓力開關本身應具有較高的信噪比，盡量減少從外界引入的干擾信號。
由于開關的靈敏度是有方向性的，當被測量是單向量，而且對其方向性要求較高，則應選擇其它方向靈敏度小的開關；如果被測量是多維向量，則要求傳感器的交叉靈敏度越小越好。
