電容式壓力變送器出現的故障都會引起變送器輸出不正常或測量不準確，但經過細心檢查，嚴格按照技術要求使用和安裝，及時采取有效措施，問題都可以排除，對不能處理的故障，應將變送器送到實驗室或生產廠家做進一步檢查。

       Faults in the capacitive pressure transmitter can cause the transmitter output to be abnormal or the measurement is inaccurate,but after careful inspection,strictly use and install according to the technical requirements,take effective measures in time,the problem can be eliminated,and the fault can not be handled.The transmitter should be sent to the laboratory or manufacturer for further inspection.

       施工現場出現的故障，絕大多數是由于使用和安裝方法不當引起的，歸納起來有幾個方面。

       Most of the failures at the construction site are caused by improper use and installation methods.There are several aspects summarized.

       1、一次元件(孔板、遠傳測量接頭等)堵塞或安裝形式不對，取壓點不合理。

       1.The primary component(orifice plate,remote transmission connector,etc.)is blocked or installed in the wrong form,and the pressure point is unreasonable.

       2、引壓管泄漏或堵塞，充液管里有殘存氣體或充氣管里有殘存液體，變送器過程法蘭中存有沉積物，形成測量死區。

       2.Leakage or blockage of the pressure guiding tube,residual gas in the liquid filling tube or residual liquid in the inflation tube,deposits in the process flange of the transmitter,forming a dead zone for measurement.

       3、變送器接線不正確，電源電壓過高或過低，指示表頭與儀表接線端子連接處接觸不良。

       3.The transmitter wiring is incorrect.The power supply voltage is too high or too low.The contact between the meter head and the meter terminal is poor.

       4、沒有嚴格按照技術要求安裝，安裝方式和現場環境不符合技術要求。

       4.It is not installed in strict accordance with technical requirements.The installation method and on-site environment do not meet the technical requirements.
