傳統測溫傳感器的優點和缺點

紅外測溫傳感器的缺點

1.易受(shou)環境因(yin)素影響（環境溫度，空氣(qi)中的(de)灰塵等）；

2.對于光亮或者拋光的金(jin)屬表(biao)面的測溫讀數影(ying)響較大；

3.只限于測量物(wu)體外部溫度(du)，不方便測量物(wu)體內部和存在障礙物(wu)時的溫度(du)。

熱電偶測溫傳感器的缺點

缺點：變化率小，需修正冷接點溫度；

Pt100測溫傳感器的缺點

熱響(xiang)應慢，耐(nai)振動和(he)耐(nai)沖擊性差，成本高，不適合測(ce)量高溫區；

PT100測溫組件整體可導電。

PT100在有電(dian)磁場干擾的情況(kuang)下(xia)，易傳(chuan)導(dao)脈沖群干擾、射(she)頻騷(sao)擾、浪涌等干擾，致使溫控器無法工作或損毀。

瞬時響應速度差。

熱敏電阻測溫傳感器的缺點

優點：可測量到小范圍內的溫度，變化率較大，固有電阻大，無需延長導線時的 誤差補償；
缺點：變化率非線性，不(bu)適(shi)合測量(liang)高溫區。
