礦用多參數通風檢測儀JFY4

由(you)低功耗單片微(wei)處理器(qi)(qi)(MCU)及(ji)外圍接(jie)口電(dian)路組(zu)成。外圍接(jie)口電(dian)路由(you)ROM、RAM，頻率/數(shu)字(zi)轉(zhuan)(zhuan)(zhuan)換(F/D)電(dian)路，模(mo)擬/數(shu)字(zi)轉(zhuan)(zhuan)(zhuan)換(A/D)電(dian)路，串行通訊電(dian)路、時鐘電(dian)路以及(ji)E2PPROM組(zu)成。壓(ya)力傳(chuan)(chuan)感(gan)器(qi)(qi)的頻率信號(hao)和(he)溫度(du)補償電(dian)壓(ya)信號(hao)分別經F/D轉(zhuan)(zhuan)(zhuan)換和(he)A/D轉(zhuan)(zhuan)(zhuan)換后(hou)送(song)入MCU計(ji)算(suan)壓(ya)力值(zhi)；MCU再將壓(ya)力值(zhi)送(song)顯示(shi)(shi)器(qi)(qi)顯示(shi)(shi)，同理風(feng)速和(he)濕度(du)傳(chuan)(chuan)感(gan)器(qi)(qi)信號(hao)也分別被F/D和(he)A/D轉(zhuan)(zhuan)(zhuan)換后(hou)送(song)入MCU計(ji)算(suan)出風(feng)速值(zhi)和(he)濕度(du)值(zhi)。溫度(du)傳(chuan)(chuan)感(gan)器(qi)(qi)的輸出為數(shu)字(zi)信號(hao)，因此不需要轉(zhuan)(zhuan)(zhuan)換，直接(jie)送(song)入MCU計(ji)算(suan)出溫度(du)值(zhi)。

礦用多參數通風檢測儀JFY4用(yong)于(yu)測(ce)量(liang)周圍環境的風(feng)速(su)、差壓、溫度和甲烷(wan)濃度。采用(yong)點陣(zhen)液晶(jing)顯示，易于(yu)讀數，且(qie)實時(shi)(shi)顯示當(dang)前(qian)測(ce)量(liang)狀態。儀(yi)器出廠前(qian)經(jing)過多次精密校準，只要正確使(shi)用(yong)可保(bao)證長時(shi)(shi)間穩(wen)定工作(zuo)。適合測(ce)量(liang)通(tong)風(feng)阻力、暖通(tong)空(kong)調、管道測(ce)量(liang)等地面(mian)場所。
