壓力開關調試期的故障
如果壓力開關在進行初次調試階段時就出現了故障，很有可能是由以下幾個方面引起的：
1.安裝不當
壓力開關如果在初次調試階段就出現了故障，首先考慮到的應該是安裝的問題。檢查壓力傳感器的安裝位置是否正確，導壓管的位置是否按照被測介質的性質進行了正確安裝。
2.參數設置的不準確
壓力開關參數的設置不當，也會引起調試出現故障，如：參數未按照規定范圍設置，超過了額定范圍，使壓力開關超負荷運行。
3.環境不符合要求
檢查壓力開關的工作環境是否符合壓力開關的使用要求，周圍是否有電磁場干擾，如果確實存在這種情況，只要將壓力開關進行良好的接地保護即可減少一定的干擾。
4.被測介質
檢查被測介質中是否混入了雜質，堵塞了導壓管道，（詳情可點擊：導壓管出現故障如何處理），最終引起了壓力開關的故障。
