壓力式溫度計的發展目標

壓(ya)(ya)力式溫(wen)(wen)度(du)(du)(du)計(ji)雖然有使用(yong)方便、觀察溫(wen)(wen)度(du)(du)(du)直觀以及離(li)測(ce)(ce)溫(wen)(wen)源(yuan)距離(li)遠都可以測(ce)(ce)溫(wen)(wen)等(deng)優點，但也有其缺點。主要是使用(yong)有色金(jin)屬(shu)(shu)多，成本高，以及容易“塞”、“漏”等(deng)損(sun)壞問(wen)題。近(jin)年來，不少使用(yong)廠家(jia)在(zai)近(jin)地測(ce)(ce)溫(wen)(wen)的溫(wen)(wen)度(du)(du)(du)計(ji)選(xuan)型上，壓(ya)(ya)力式溫(wen)(wen)度(du)(du)(du)計(ji)被(bei)雙金(jin)屬(shu)(shu)溫(wen)(wen)度(du)(du)(du)計(ji)和熱電偶、熱電阻溫(wen)(wen)度(du)(du)(du)計(ji)所(suo)替代。
隨著計算(suan)機(ji)在工業設備上的(de)應用(yong)，要(yao)求壓力式溫(wen)(wen)(wen)度計在基地現場測溫(wen)(wen)(wen)的(de)同(tong)時，能(neng)與計算(suan)機(ji)接口。為此在壓力式溫(wen)(wen)(wen)度計的(de)測溫(wen)(wen)(wen)元件內埋設了可同(tong)步感溫(wen)(wen)(wen)的(de)熱電(dian)阻，使之有(you)一(yi)個電(dian)信號輸出(chu)，進而(er)轉(zhuan)換與計算(suan)機(ji)接口，形成了機(ji)電(dian)一(yi)體化的(de)壓力式溫(wen)(wen)(wen)度計。這種(zhong)溫(wen)(wen)(wen)度計的(de)使用(yong)如(ru)今(jin)呈(cheng)現上升趨勢
一般(ban)壓(ya)(ya)力(li)式(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)度計(ji)(ji)均為單圈彈(dan)簧(huang)管(guan)(guan)(guan)壓(ya)(ya)力(li)式(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)度計(ji)(ji)，又稱C型彈(dan)簧(huang)管(guan)(guan)(guan)式(shi)(shi)(shi)壓(ya)(ya)力(li)式(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)度計(ji)(ji)。因其結構簡單，生產成本比(bi)較低，而被廣泛應用(yong)(yong)。此外還有多(duo)圈彈(dan)簧(huang)管(guan)(guan)(guan)式(shi)(shi)(shi)壓(ya)(ya)力(li)式(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)度計(ji)(ji)，它可以比(bi)單圈彈(dan)簧(huang)管(guan)(guan)(guan)式(shi)(shi)(shi)壓(ya)(ya)力(li)式(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)度計(ji)(ji)輸出(chu)更大的轉(zhuan)動力(li)矩，特(te)別適(shi)用(yong)(yong)于自動記(ji)錄式(shi)(shi)(shi)壓(ya)(ya)力(li)式(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)度計(ji)(ji)或附帶更多(duo)的接點。國內已有個別廠家從事多(duo)圈彈(dan)簧(huang)管(guan)(guan)(guan)式(shi)(shi)(shi)壓(ya)(ya)力(li)式(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)度計(ji)(ji)的研(yan)究及試(shi)制，且已批量投產，頗受用(yong)(yong)戶(hu)好評。
壓力(li)(li)式(shi)(shi)溫(wen)度(du)計(ji)(ji)除采(cai)用(yong)(yong)(yong)彈簧(huang)管(guan)作(zuo)(zuo)為(wei)彈性元件外，還可以(yi)采(cai)用(yong)(yong)(yong)膜盒或(huo)波(bo)紋管(guan)。膜盒或(huo)波(bo)紋管(guan)主(zhu)要用(yong)(yong)(yong)于溫(wen)度(du)信號變送器(qi)或(huo)溫(wen)度(du)調節器(qi)，該類型的壓力(li)(li)式(shi)(shi)溫(wen)度(du)計(ji)(ji)國(guo)內多家企(qi)業已能(neng)生產。變壓器(qi)行業專用(yong)(yong)(yong)壓力(li)(li)式(shi)(shi)溫(wen)度(du)計(ji)(ji)則大多數采(cai)用(yong)(yong)(yong)波(bo)紋管(guan)作(zuo)(zuo)為(wei)彈性元件。冰箱溫(wen)度(du)控制器(qi)一般用(yong)(yong)(yong)膜盒作(zuo)(zuo)為(wei)壓力(li)(li)式(shi)(shi)溫(wen)度(du)計(ji)(ji)的彈性元件。
