壓力開關輸出不準的原因
壓力開關在測量過程中輸出信號不準的情況偶爾會出現，而造成此現象的原因主要有：
一、壓力開關的安裝環境不當
壓力開關不適宜安裝在強振動，且帶強電磁場的場合下，否則就會使壓力開關因干擾而感應到錯誤的信號，最終出現了輸出不準的情況。
二、壓力開關的被測介質不符
壓力開關所測量的介質都必須是符合其使用要求的，否則在測量壓力時便會出現忽大忽小的情況，影響了最終輸出。
三、壓力開關的接線不良
如果是電子式壓力開關出現了輸出不準的情況，則很有可能是接線未連接完整，影響了信號的傳輸。
四、壓力開關的電源不符
對于電子式壓力開關來說，它的工作是需要電源供電才可進行的，當電源超出了其使用要求時，就很容易出現錯誤的輸出信號。
