變送器有很多種，屬于控制儀器儀表的范籌。一般來說，變送器向二次儀表發(fā)送一個(gè)信號(hào)來顯示自身所測(cè)量的數(shù)據(jù)。將物理測(cè)量信號(hào)或普通電信號(hào)能過電器元件轉(zhuǎn)換為標(biāo)準(zhǔn)電信號(hào)輸出或可通過通信協(xié)議輸出的裝置。一般分為：溫濕度變送器、壓力變送器、差壓變送器、流量變送器、重量變送器等等。變送器-遵循物理定律（或?qū)嶒?yàn)數(shù)學(xué)模型）將物理量的變化轉(zhuǎn)換為標(biāo)準(zhǔn)信號(hào)（如4-20毫安）的裝置。有0/4-20mADC、1-5Vdc、0-10Vdc等，不同功能的變送器轉(zhuǎn)換信號(hào)不一樣。它除傳感功能外，還具有對(duì)電子信號(hào)的放大整形功能，輸出為標(biāo)準(zhǔn)控制信號(hào)。 </p> <p> <br /> </p> <p> 變送器的二線和四線信號(hào)傳輸方式是什么？在二線制傳輸方式下，電源、負(fù)載電阻和發(fā)射機(jī)串聯(lián)，即兩線同時(shí)傳輸發(fā)射機(jī)所需的電源和輸出電流信號(hào)。目前，大多數(shù)發(fā)射機(jī)是二線制發(fā)射機(jī)，在四線制系統(tǒng)中，電源和負(fù)載電阻分別與發(fā)射機(jī)相連，即電源和發(fā)射機(jī)輸出信號(hào)分別與二線制傳輸相連。上海銷售轉(zhuǎn)速變送器</p><p
