壓力開關的常用參數解析
在使用壓力開關進行測量工作時，各項性能參數在生產中起到了指導性的作用，在使用之前務必要對參數有一定了解。
1.設定值是指壓力開關的設定壓力，即壓力開關所控制的壓力大小，如果是可調的就稱可調節設定值，不可調的就是不可調設定值。
2.切換差是指壓力的最高值與最低值之差。
3.設定值范圍是指在規定范圍內可以連續調節的區域，最大值稱為上限值，最小值為下限值。
4.損壞壓力是指：在不損壞壓力開關范圍之內所能承受的最大壓力。
5.最大壓力范圍是指壓力開關能長時間承受的最大壓力值，此壓力值不會導致輸出特性的改變，日常使用中，為了不損壞壓力開關且提高壓力開關的特性，一般都會適當的減小額定壓力范圍，設定的最大壓力范圍一般是額定壓力最大值的2倍或者3倍。
了解了上述有關壓力開關的常用參數之后，才可以合理運用壓力開關，實現壓力開關的最大價值。
