無(wu)錫徽科特測控技術有限(xian)公司告訴(su)你：什么(me)叫(jiao)溫(wen)濕度(du)發(fa)生器(qi)(qi)？溫(wen)濕度(du)發(fa)生器(qi)(qi)HDT3601的(de)作用(yong)原理(li)(li)又是什么(me)？溫(wen)度(du)發(fa)生器(qi)(qi)是選用(yong)礦燈電(dian)池供(gong)電(dian)，使(shi)用(yong)NTC熱敏電(dian)阻因升(sheng)溫(wen)而(er)電(dian)阻下降、經過反應減少(shao)加熱的(de)驅動電(dian)流的(de)原理(li)(li)，從(cong)而(er)到達恒(heng)溫(wen)的(de)意圖。發(fa)生80C溫(wen)度(du)，可用(yong)于校(xiao)驗煤礦膠(jiao)帶運輸機的(de)溫(wen)度(du)保護傳(chuan)感器(qi)(qi)。

　　羅卓尼克溫(wen)濕(shi)度(du)發(fa)生(sheng)器(qi)、維(wei)薩拉溫(wen)濕(shi)度(du)發(fa)生(sheng)器(qi)、密(mi)析爾溫(wen)濕(shi)度(du)發(fa)生(sheng)器(qi)等作業(ye)原理：

　　溫(wen)濕度(du)(du)(du)(du)發(fa)生(sheng)器(qi)是(shi)依據大(da)(da)功率三(san)極管作(zuo)(zuo)業(ye)(ye)發(fa)熱正(zheng)比于(yu)lC×UC原理制作(zuo)(zuo)的(de)(de)。大(da)(da)功率三(san)極管3DD15是(shi)發(fa)熱體，電(dian)(dian)阻R2、R3、R4、R5電(dian)(dian)橋電(dian)(dian)路(lu)用(yong)于(yu)控溫(wen)，發(fa)光(guang)二極管Dl用(yong)于(yu)電(dian)(dian)源指示，D2用(yong)于(yu)預(yu)定溫(wen)度(du)(du)(du)(du)發(fa)光(guang)指示。NTC負(fu)溫(wen)度(du)(du)(du)(du)系(xi)數熱敏電(dian)(dian)阻R3貼裝于(yu)3DD15金(jin)屬外(wai)(wai)(wai)殼(ke)外(wai)(wai)(wai)表，監(jian)控溫(wen)度(du)(du)(du)(du)改(gai)變(bian)。3DD15金(jin)屬外(wai)(wai)(wai)殼(ke)外(wai)(wai)(wai)表還(huan)固定有直徑lcm長5cm的(de)(de)鋁管，用(yong)于(yu)放置被測溫(wen)度(du)(du)(du)(du)傳感(gan)(gan)器(qi)探頭。作(zuo)(zuo)業(ye)(ye)后跟著溫(wen)度(du)(du)(du)(du)的(de)(de)升(sheng)高(gao)R3阻值逐漸變(bian)小，a、b兩點壓(ya)(ya)差逐漸加(jia)大(da)(da)。當到(dao)達(da)D2導通電(dian)(dian)壓(ya)(ya)時，發(fa)光(guang)指示設(she)定溫(wen)度(du)(du)(du)(du)已到(dao)（約Smin），能夠校驗溫(wen)度(du)(du)(du)(du)傳感(gan)(gan)器(qi)，此(ci)刻3DD15金(jin)屬外(wai)(wai)(wai)殼(ke)外(wai)(wai)(wai)表約70℃左(zuo)右。剛作(zuo)(zuo)業(ye)(ye)時電(dian)(dian)流(liu)約3A左(zuo)右，跟著溫(wen)度(du)(du)(du)(du)升(sheng)高(gao)b點電(dian)(dian)壓(ya)(ya)升(sheng)高(gao)，Tl、T2導通程(cheng)度(du)(du)(du)(du)減(jian)弱(ruo)，隨即電(dian)(dian)流(liu)減(jian)小，到(dao)達(da)80C左(zuo)右時溫(wen)度(du)(du)(du)(du)不再升(sheng)高(gao)并保持，此(ci)刻電(dian)(dian)流(liu)約1.。此(ci)設(she)備的(de)(de)優點是(shi)不需要現場另接電(dian)(dian)源，而是(shi)使用(yong)礦(kuang)工(gong)自己帶(dai)著的(de)(de)礦(kuang)燈(deng)電(dian)(dian)瓶(ping)(7Ah/4.2V)供電(dian)(dian)，摘下礦(kuang)燈(deng)擰上即可(ke)，即便(bian)利又防爆(bao)。
