位差的單位是度或弧度，正、負號表示搶先或滯后聯(lián)系。待測相位差的正弦電量的頻率規(guī)模很廣，因此選用的丈量辦法和儀器一般隨頻率的高低來挑選。常用的辦法是直接法和間接法。間接法一般選用三電壓表法。 -般要求兩電壓信號有一-公共點(設(shè)為a點)，當(dāng)分別測出兩信號電壓Uab、Uca, 以及兩電壓的差值Ubc后, 可畫出電壓三角形。按余弦定理,兩信號電壓間的相位差當(dāng)$很小時,可將Uab或Uca中較大的一個信號電壓分壓，使分壓后兩信號的數(shù)值相等。江蘇RETS-100L相位差測量儀口碑推薦精心打造的每一-臺設(shè)備出貨前都會用**計量標(biāo)準片進行校驗。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">相位檢測儀器工作原理數(shù)字相位計一般采用相位-電壓轉(zhuǎn)換法的相位差數(shù)字化測量方法.它測量的是同頻信號的相位差，相位差為φ的兩個同頻信號U1(t)和 U2(t)分別經(jīng)過各自的衰減電路被衰減成為振幅在0.6V到2.0V的基準電壓，然后送至相應(yīng)的整形電路整形為方波，此時對稱調(diào)整電路會對這兩個信號進行對稱調(diào)整，使得測量結(jié)果更準確，這樣就得到了兩個同頻方波信號，再經(jīng)過鑒相脈沖電路得到一個隨相位差變化而變化的脈沖信號 △t.相位差的數(shù)字化是采用填充計數(shù)法實現(xiàn)的，即用周期為τ的脈沖分別對△t和T進行計數(shù)，則相位差:φ=△tTX360° =n1 Tn2τ X360° =n1n2X360°式子中T為兩個被測信號的周期，n1為△t時間內(nèi)所填充的脈沖個數(shù), n2為T時間內(nèi)所填充的脈沖個數(shù)。由于不同的信號電壓大小不同，所以他們需要進入不同的衰減電路,才能保證整個電路的安全和測量的準確性,這就需要一個精確的自動換程電路.而后續(xù)的信號處理需要--個幅值穩(wěn)定在-一個范圍內(nèi)的基準信號，這就需要通過衰減器來實現(xiàn).江蘇光學(xué)膜相位差測量儀質(zhì)量推薦</p><p
