K-TEK液位計(jì) 07-T1051 華東特惠

K-TEK is a premier manufacturer of precision metal stampings and sheet metal fabrications. For almost 40 years K-TEK has exceeded customer expectations in the manufacturing of stampings, weldments, mechanical assemblies, and wire forms. K-TEK works with a variety of OEM customers both domestically and internationally. K-TEK has two locations strategically located to serve the domestic manufacturing centers. K-TEK Wisconson is located in Baldwin Wisconsin just a short drive outside of the Minneapolis-St. Paul metro area, focusing on the Midwest. K-TEK Carolina in Charlotte North Carolina is centrally located to serve the growing Southeast market. Our highly trained, experienced staff is ready to assist you on your next project. Please contact us for a quick, competitive quotation.

We have expertise in all forms of welding

MIG – Can be used for many times of metals and is well suited for long welds and thick sections. Can be performed in any orientation and requires little post-weld cleanup.

TIG – Clean, high quality welds with little distortion but slower and less suited for thick sections than MIG welding.

Robotic – Faster, more precise welds with greater consistency and quality.

Spot Welding - We have automatic nut feeders for M6, M8, and M10.

射頻導(dǎo)納料位計(jì)的工作原理介紹：點(diǎn)位射頻導(dǎo)納技術(shù)與電容技術(shù)的重要區(qū)別是采用了三端技術(shù)。在電路單元測(cè)量信號(hào)上引出一根線，經(jīng)同相放大器放大，其輸出與同軸電纜屏蔽層相連，然后連接到探頭的屏蔽層上。該放大器是一個(gè)同相放大器，其增益為“1”，輸出信號(hào)與輸入信號(hào)等電位，同相位，同頻率，但互相隔離。地線是電纜中外面的屏蔽層。由于同軸電纜的中心線與中間屏蔽存在上述關(guān)系，所以二者之間沒(méi)有電位差，也就沒(méi)有電流流過(guò)，即沒(méi)有電流從中心線漏出來(lái)，相當(dāng)于二者之間沒(méi)有電容或者說(shuō)電容為零。因此電纜的溫度效應(yīng)，安裝電容等也就不會(huì)產(chǎn)生影響。對(duì)于探頭上的掛料問(wèn)題，采用一種新的探頭結(jié)構(gòu)，五層同心結(jié)構(gòu)：里層是中心測(cè)桿，中間是中心屏蔽層，外邊是接地的安裝螺紋，用絕緣層將其分別隔離開(kāi)來(lái)。

與同軸電纜的情況是一樣的，中心測(cè)桿與屏蔽層之間沒(méi)有電勢(shì)差，即使傳感元件上掛料阻抗很小，也不會(huì)有電流流過(guò)，電子儀器測(cè)量的僅僅是從探頭中心到對(duì)面罐壁的電流，因?yàn)橹行脑茏璧K電流沿探頭向上流向容器壁，因而對(duì)地電流只有經(jīng)探頭末端通過(guò)被測(cè)物料到對(duì)面容器。即Ua=Ub lab=(Ua－Ub)/R=0。由于屏蔽層與容器壁之間存在電勢(shì)差，兩者之間雖有電流流過(guò)，但是該電流不被測(cè)量，不影響測(cè)量結(jié)果。這樣就將測(cè)量端保護(hù)起來(lái)，不受掛料的影響。只有容器中的物位確實(shí)上升接觸到中心測(cè)量桿時(shí)，通過(guò)被測(cè)物料，中心測(cè)桿與地之間形成被測(cè)電流。
