如何檢查壓力開關的檢測元件
壓力傳感器是壓力開關檢測信號的重要元件，所有的信號傳輸都要基于它的工作之上，是組成壓力開關整體結構的必不可少的元件。所以，為了保證用戶的正常工作與生產，今天小編為大家介紹如何檢查壓力傳感器。
壓力傳感器一旦出現故障，就會檢測不到壓力信號，引起整個壓力開關都無輸出或者輸出不正常的現象時，應該首先檢查壓力開關的敏感元件，具體的方法如下：
拆下法蘭接口，檢查壓力傳感器的內部膜片是否出現了變形、破損或者是漏油的現象，如果的確出現了這種情況，要立即更換一個新的壓力傳感器。如果不知道如何檢查泄漏情況，可按下述方法進行：接通電路和氣路，當壓力信號呈現上升值時，關閉掉壓力源，輸出電壓和讀數值應該是穩定不動的情況，如果輸出電壓出現下降的情況，那就說明壓力傳感器的確出現了泄漏，可用肥皂水檢查出泄漏部位。
