發(fā)動(dòng)機(jī)轉(zhuǎn)速儀,振動(dòng)轉(zhuǎn)速表用途

更新時(shí)間:2021-07-01點(diǎn)擊次數(shù):1116

發(fā)動(dòng)機(jī)轉(zhuǎn)速儀振動(dòng)轉(zhuǎn)速表型號(hào):DP-S2682

 

 

發(fā)動(dòng)機(jī)轉(zhuǎn)速儀是通過發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)時(shí)產(chǎn)生的機(jī)械振動(dòng)來提取發(fā)動(dòng)機(jī)轉(zhuǎn)速的儀器。轉(zhuǎn)速儀內(nèi)置3.7V鋰電池,采用了無線通信的方式,適用于汽油、柴油、天然氣車輛的轉(zhuǎn)速測(cè)試。

 

 測(cè)試原理

轉(zhuǎn)速儀采集發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)時(shí)產(chǎn)生的機(jī)械振動(dòng)以及聲音信號(hào),并對(duì)信號(hào)行放大濾波處理,從復(fù)雜的信號(hào)中提取出與發(fā)動(dòng)機(jī)轉(zhuǎn)速相關(guān)的頻率,通過特定的算法得到轉(zhuǎn)速。

 

 術(shù)標(biāo)

◆測(cè)量對(duì)象:汽油/天然氣/柴油車 ◆作溫度:-20℃~+50℃

◆轉(zhuǎn)速度:±1% 或±10rpm    ◆響應(yīng)時(shí)間:<0.3S

◆測(cè)量范圍:500~6000rpm
