二、儀器的結(jié)構(gòu)

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

⑴ 濕球溫度傳感器測(cè)頭：                                     

 測(cè)量范圍: 5～40℃                                               

 準(zhǔn)確度: ±0.5℃                                                  

⑵黑球溫度傳感器測(cè)頭：                                             

測(cè)量范圍：20～120℃                                               

準(zhǔn)確度：20～50℃ ±0.5℃ ;                                        

 50～120℃ ±1℃                                                    

⑶干球溫度傳感器測(cè)頭：                                                

測(cè)量范圍：10～60℃                                                   

準(zhǔn)確度： ±0.5℃                                                       

2.數(shù)字顯示儀表                                                               

顯示儀表完全應(yīng)用數(shù)字電路，按設(shè)計(jì)要                                       

求實(shí)現(xiàn)全部的五組數(shù)字顯示，和時(shí)間顯示，
