溫(wen)濕(shi)度(du)(du)傳(chuan)感器HTS/HTD系列，配有(you)電(dian)(dian)容(rong)式相(xiang)對濕(shi)度(du)(du)傳(chuan)感元件和(he)一個標準的帶隙(xi)溫(wen)度(du)(du)傳(chuan)感元件，電(dian)(dian)容(rong)式相(xiang)對濕(shi)度(du)(du)傳(chuan)感元件是由高(gao)分子薄膜電(dian)(dian)容(rong)制成。當環境濕(shi)度(du)(du)改變時，薄膜電(dian)(dian)容(rong)的介(jie)電(dian)(dian)常數(shu)發(fa)生(sheng)變化，其電(dian)(dian)容(rong)量(liang)(liang)也發(fa)生(sheng)變化，其電(dian)(dian)容(rong)變化量(liang)(liang)與相(xiang)對濕(shi)度(du)(du)成正比。
