傳(chuan)感(gan)器(qi)(qi)(qi)(qi)是(shi)能(neng)夠(gou)受(shou)規定(ding)的(de)(de)(de)(de)(de)(de)(de)被測(ce)量并按(an)照一定(ding)的(de)(de)(de)(de)(de)(de)(de)規律轉(zhuan)換(huan)(huan)成(cheng)(cheng)(cheng)可用輸(shu)出信(xin)(xin)號(hao)(hao)(hao)(hao)的(de)(de)(de)(de)(de)(de)(de)器(qi)(qi)(qi)(qi)件(jian)(jian)或(huo)裝置的(de)(de)(de)(de)(de)(de)(de)總稱,通(tong)常由敏感(gan)元(yuan)件(jian)(jian)和(he)(he)(he)轉(zhuan)換(huan)(huan)元(yuan)件(jian)(jian)組成(cheng)(cheng)(cheng)。當傳(chuan)感(gan)器(qi)(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)(de)輸(shu)出為規定(ding)的(de)(de)(de)(de)(de)(de)(de)標準信(xin)(xin)號(hao)(hao)(hao)(hao)時(shi)(shi)，則稱為變(bian)(bian)送(song)(song)器(qi)(qi)(qi)(qi)。 變(bian)(bian)送(song)(song)器(qi)(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)(de)概念是(shi)將非(fei)(fei)(fei)(fei)標準電(dian)(dian)信(xin)(xin)號(hao)(hao)(hao)(hao)轉(zhuan)換(huan)(huan)為標準電(dian)(dian)信(xin)(xin)號(hao)(hao)(hao)(hao)的(de)(de)(de)(de)(de)(de)(de)儀(yi)器(qi)(qi)(qi)(qi)，傳(chuan)感(gan)器(qi)(qi)(qi)(qi)則是(shi)將物(wu)(wu)理(li)(li)信(xin)(xin)號(hao)(hao)(hao)(hao)轉(zhuan)換(huan)(huan)為電(dian)(dian)信(xin)(xin)號(hao)(hao)(hao)(hao)的(de)(de)(de)(de)(de)(de)(de)器(qi)(qi)(qi)(qi)件(jian)(jian)，過去(qu)常講物(wu)(wu)理(li)(li)信(xin)(xin)號(hao)(hao)(hao)(hao)，現(xian)在(zai)其他信(xin)(xin)號(hao)(hao)(hao)(hao)也有了。一次儀(yi)表(biao)(biao)指(zhi)現(xian)場測(ce)量儀(yi)表(biao)(biao)或(huo)基(ji)地(di)控(kong)(kong)制(zhi)表(biao)(biao)，二次儀(yi)表(biao)(biao)指(zhi)利用一次表(biao)(biao)信(xin)(xin)號(hao)(hao)(hao)(hao)完成(cheng)(cheng)(cheng)其他功能(neng)：諸如控(kong)(kong)制(zhi)，顯(xian)示(shi)(shi)等功能(neng)的(de)(de)(de)(de)(de)(de)(de)儀(yi)表(biao)(biao)。 傳(chuan)感(gan)器(qi)(qi)(qi)(qi)和(he)(he)(he)變(bian)(bian)送(song)(song)器(qi)(qi)(qi)(qi)本是(shi)熱工儀(yi)表(biao)(biao)的(de)(de)(de)(de)(de)(de)(de)概念。傳(chuan)感(gan)器(qi)(qi)(qi)(qi)是(shi)把(ba)非(fei)(fei)(fei)(fei)電(dian)(dian)物(wu)(wu)理(li)(li)量如溫(wen)度、壓(ya)力、液位、物(wu)(wu)料、氣(qi)(qi)體特性等轉(zhuan)換(huan)(huan)成(cheng)(cheng)(cheng)電(dian)(dian)信(xin)(xin)號(hao)(hao)(hao)(hao)或(huo)把(ba)物(wu)(wu)理(li)(li)量如壓(ya)力、液位等直(zhi)接(jie)送(song)(song)到(dao)(dao)變(bian)(bian)送(song)(song)器(qi)(qi)(qi)(qi)。變(bian)(bian)送(song)(song)器(qi)(qi)(qi)(qi)則是(shi)把(ba)傳(chuan)感(gan)器(qi)(qi)(qi)(qi)采集(ji)到(dao)(dao)的(de)(de)(de)(de)(de)(de)(de)微(wei)弱(ruo)的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)信(xin)(xin)號(hao)(hao)(hao)(hao)放(fang)大以(yi)便(bian)(bian)轉(zhuan)送(song)(song)或(huo)啟(qi)動(dong)控(kong)(kong)制(zhi)元(yuan)件(jian)(jian)。或(huo)將傳(chuan)感(gan)器(qi)(qi)(qi)(qi)輸(shu)入的(de)(de)(de)(de)(de)(de)(de)非(fei)(fei)(fei)(fei)電(dian)(dian)量轉(zhuan)換(huan)(huan)成(cheng)(cheng)(cheng)電(dian)(dian)信(xin)(xin)號(hao)(hao)(hao)(hao)同(tong)(tong)時(shi)(shi)放(fang)大以(yi)便(bian)(bian)供遠(yuan)方(fang)測(ce)量和(he)(he)(he)控(kong)(kong)制(zhi)的(de)(de)(de)(de)(de)(de)(de)信(xin)(xin)號(hao)(hao)(hao)(hao)源。根據需要(yao)(yao)還可將模擬量變(bian)(bian)換(huan)(huan)為數字(zi)量。傳(chuan)感(gan)器(qi)(qi)(qi)(qi)和(he)(he)(he)變(bian)(bian)送(song)(song)器(qi)(qi)(qi)(qi)一同(tong)(tong)構(gou)成(cheng)(cheng)(cheng)自動(dong)控(kong)(kong)制(zhi)的(de)(de)(de)(de)(de)(de)(de)監(jian)測(ce)信(xin)(xin)號(hao)(hao)(hao)(hao)源。不同(tong)(tong)的(de)(de)(de)(de)(de)(de)(de)物(wu)(wu)理(li)(li)量需要(yao)(yao)不同(tong)(tong)的(de)(de)(de)(de)(de)(de)(de)傳(chuan)感(gan)器(qi)(qi)(qi)(qi)和(he)(he)(he)相應的(de)(de)(de)(de)(de)(de)(de)變(bian)(bian)送(song)(song)器(qi)(qi)(qi)(qi)。還有一種(zhong)(zhong)變(bian)(bian)送(song)(song)器(qi)(qi)(qi)(qi)不是(shi)將物(wu)(wu)理(li)(li)量變(bian)(bian)換(huan)(huan)成(cheng)(cheng)(cheng)電(dian)(dian)信(xin)(xin)號(hao)(hao)(hao)(hao)，如一種(zhong)(zhong)鍋爐(lu)水位計的(de)(de)(de)(de)(de)(de)(de)“差(cha)壓(ya)變(bian)(bian)送(song)(song)器(qi)(qi)(qi)(qi)”，他是(shi)將液位傳(chuan)感(gan)器(qi)(qi)(qi)(qi)里的(de)(de)(de)(de)(de)(de)(de)下部(bu)的(de)(de)(de)(de)(de)(de)(de)水和(he)(he)(he)上(shang)部(bu)蒸汽的(de)(de)(de)(de)(de)(de)(de)冷凝水通(tong)過儀(yi)表(biao)(biao)管(guan)送(song)(song)到(dao)(dao)變(bian)(bian)送(song)(song)器(qi)(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)(de)波紋管(guan)兩(liang)側，以(yi)波紋管(guan)兩(liang)側的(de)(de)(de)(de)(de)(de)(de)差(cha)壓(ya)帶動(dong)機械放(fang)大裝置用指(zhi)針(zhen)指(zhi)示(shi)(shi)水位的(de)(de)(de)(de)(de)(de)(de)一種(zhong)(zhong)遠(yuan)方(fang)儀(yi)表(biao)(biao)。當然還有把(ba)電(dian)(dian)氣(qi)(qi)模擬量變(bian)(bian)換(huan)(huan)成(cheng)(cheng)(cheng)數字(zi)量的(de)(de)(de)(de)(de)(de)(de)也可以(yi)叫變(bian)(bian)送(song)(song)器(qi)(qi)(qi)(qi)。以(yi)上(shang)只是(shi)從概念上(shang)說(shuo)明傳(chuan)感(gan)器(qi)(qi)(qi)(qi)和(he)(he)(he)變(bian)(bian)送(song)(song)器(qi)(qi)(qi)(qi)的(de)(de)(de)(de)(de)(de)(de)區別
