雙法蘭液位變送器是用于防止管道中的介質(zhì)直接進(jìn)入變送器里的壓力傳感器組件，它與變送器之間是靠注滿流體的毛細(xì)管連接起來的。用于測量液體、氣體或蒸汽的液位、流量和壓力，然后將其轉(zhuǎn)變成4～20mADC信號輸出。雙法蘭液位變送器選型的時候尤其要注意一個很重要的因素，就是差壓式液位變送器，它是安裝在液體容器的底部，通過表壓信號來反映液位的高度。在制藥、化工行業(yè)的液位測量的控制過程中，盛裝液體的容器經(jīng)常處于有壓的情況下，此時常規(guī)的靜壓式液位變送器變不能滿足測量要求，由于在傳感器電路和結(jié)構(gòu)上的改進(jìn)，提高了差壓液位測量技術(shù)在制藥和食品行業(yè)的實用價值。

 

　　The double flange liquid level transmitter is a pressure sensor component used to prevent the medium in the pipeline from directly entering the transmitter.It is connected to the transmitter by a capillary filled with fluid.It is used to measure the level,flow and pressure of liquid,gas or steam,and then convert it into 4-20mADC signal output.When selecting a double-flange liquid level transmitter,it is especially important to pay attention to a very important factor,which is the differential pressure liquid level transmitter,which is installed at the bottom of the liquid container and reflects the height of the liquid level through the gauge pressure signal..In the control process of liquid level measurement in the pharmaceutical and chemical industries,the container containing the liquid is often under pressure.At this time,the conventional static pressure liquid level transmitter cannot meet the measurement requirements,due to the sensor circuit and structure The above improvements have improved the practical value of differential pressure level measurement technology in the pharmaceutical and food industries.

 

　　雙法蘭液位變送器如何檢修：

 

　　How to overhaul the double flange liquid level transmitter:

 

　　①變送器的檢修周期一般為生產(chǎn)裝置的一個運(yùn)行周期。

 

　　①The maintenance cycle of the transmitter is generally an operating cycle of the production device.

 

　　②儀表與設(shè)備連接部位有排污孔的應(yīng)拆開堵頭進(jìn)行吹掃（吹掃時應(yīng)注意不要用蒸汽對著法蘭膜片）。

 

　　②If there is a drain hole at the connection part of the instrument and the equipment,the plug should be removed for purging(be careful not to use steam against the flange diaphragm when purging).

 

　　③儀表與設(shè)備連接部位無排污孔的應(yīng)拆開法蘭進(jìn)行吹掃。

 

　　③If there is no drain hole at the connection part of the instrument and the equipment,the flange should be disassembled for purging.

 

　　④檢查零部件有無腐蝕磨損、變形和滲漏，情況嚴(yán)重者應(yīng)更換。

 

　　④Check the parts for corrosion,wear,deformation and leakage.If the situation is serious,replace them.
