QNCS-A氣動(dòng)內(nèi)徑測(cè)量頭及校對(duì)規(guī) QNCS-A
型號(hào)：
φ3-φ150mm
與啟動(dòng)量?jī)x配套，用作一般形式的通孔測(cè)量。被測(cè)孔徑長(zhǎng)度＞6.5mm.
注：當(dāng)被測(cè)孔長(zhǎng)度超過70毫米時(shí)，應(yīng)注明孔的長(zhǎng)度以便選配合適。
氣動(dòng)量?jī)x的原理就是在某個(gè)區(qū)間氣體流量與間隙成線性關(guān)系，上下極限校對(duì)規(guī)的作用是，讓你在這個(gè)上下范圍內(nèi)確定線性沒有問題，如果只要一個(gè)比對(duì)，無法判斷是否整個(gè)區(qū)間都是線性關(guān)系，有可能出現(xiàn)測(cè)量值與實(shí)際值不符。
