產(chǎn)品詳細(xì)介紹：
XJP-48T100數(shù)字顯示儀，具有五位LED顯示及參數(shù)設(shè)定功能，可與接近開關(guān)、霍爾光電、磁電等各類轉(zhuǎn)速傳感器配套，用來(lái)測(cè)量轉(zhuǎn)速、線速度和角速度。由于參數(shù)可設(shè)定，使各種物理量的直讀變顯得更加方便。
工作原理
該顯示儀由單芯片微處理器AT89C2051構(gòu)成智能化儀表，對(duì)傳感器轉(zhuǎn)換來(lái)的被測(cè)頻率信號(hào)進(jìn)行測(cè)量。測(cè)量基本原理是：?jiǎn)纹瑱C(jī)在測(cè)量頻率脈沖數(shù)的同時(shí)，同步計(jì)時(shí)，并在一個(gè)采樣周期內(nèi)將計(jì)數(shù)脈沖除以時(shí)間，再乘以設(shè)定和系數(shù)，直接顯示被測(cè)物理量。
參數(shù)與規(guī)格：
測(cè)量范圍：0.000l～99999.(小數(shù)點(diǎn)可任意設(shè)定)
系數(shù)設(shè)定范圍：0.0001～99999.
輸入信號(hào)范圍：1Hz～10 kHz
輸入信號(hào)幅值：
正弦波0.3～10V(有效值)
矩形波0.5～12V(峰 峰值)
準(zhǔn)確度等級(jí)：0.02級(jí)
供電電源：220V、50Hz(AC)
正常工作條件：
溫度：0～40℃
相對(duì)濕度：不大于85％
大氣壓力：86～106KPa
周圍空氣中應(yīng)不含有易燃、易爆的物質(zhì)
開孔尺寸：（75×150）mm
外形尺寸：（80×160×130）mm高×寬×深
