德國(guó)STW壓力傳感器、STW壓力變送器、STW壓力開關(guān)、STW液位傳感器等產(chǎn)品。
STW壓力傳感器是工業(yè)實(shí)踐中最為常用的一種傳感器，其廣泛應(yīng)用于各種工業(yè)自控環(huán)境，涉及水利水電、鐵路交通、智能建筑、生產(chǎn)自控、航空航天、軍工、石化、油井、電力、船舶、機(jī)床、管道等眾多行業(yè)，力學(xué)傳感器的種類繁多，如電阻應(yīng)變片壓力傳感器、半導(dǎo)體應(yīng)變片壓力傳感器、壓阻式壓力傳感器、電感式壓力傳感器、電容式壓力傳感器、諧振式壓力傳感器及電容式加速度傳感器等。但應(yīng)用最為廣泛的是壓阻式壓力傳感器，它具有極低的價(jià)格和較高的精度以及較好的線性特性。STW壓力變送器和差壓變送器單從名稱上講測(cè)量的是壓力和差壓（兩個(gè)壓力的差），但它們可以間接測(cè)量的量卻很多。如STW壓力變送器，除可以測(cè)量壓力外，還可以測(cè)量設(shè)備內(nèi)的液位。在常壓容器內(nèi)測(cè)量液位時(shí)，需要一臺(tái)壓力變送器即可。當(dāng)測(cè)量受壓容器的液位時(shí)，可考慮用兩臺(tái)壓力/差壓變送器，即測(cè)量下限一臺(tái)，測(cè)量上限一臺(tái)，它們的輸出信號(hào)進(jìn)行減法運(yùn)算，即可測(cè)出液位，這時(shí)一般選用差壓變送器。在容器內(nèi)液位與壓力值不變的情況下它還可以用來(lái)測(cè)量介質(zhì)的密度。
