二、儀器的結構

WBGT指數儀由測頭(自然濕球、黑球、干球三個溫度傳感器分別平行安裝在一個橫架上)和智能數字顯示儀表兩部分組成。

⑴ 濕球溫度傳感器測頭：                                     

 測量范圍: 5～40℃                                               

 準確度: ±0.5℃                                                  

⑵黑球溫度傳感器測頭：                                             

測量范圍：20～120℃                                               

準確度：20～50℃ ±0.5℃ ;                                        

 50～120℃ ±1℃                                                    

⑶干球溫度傳感器測頭：                                                

測量范圍：10～60℃                                                   

準確度： ±0.5℃                                                       

2.數字顯示儀表                                                               

顯示儀表完全應用數字電路，按設計要                                       

求實現全部的五組數字顯示，和時間顯示，
