舊國(guó)標(biāo)將應(yīng)用對(duì)象和使用環(huán)境條件*不同的“稱重”和“測(cè)力”兩種傳感器合二為一來(lái)考慮,對(duì)試驗(yàn)和評(píng)價(jià)方法未給予區(qū)分。舊國(guó)標(biāo)共有21項(xiàng)指標(biāo),均在常溫下進(jìn)行試驗(yàn);并用非線性、滯后誤差、重復(fù)性誤差、蠕變、零點(diǎn)溫度附加誤差以及額定輸出溫度附加誤差6項(xiàng)指標(biāo)中的zui大誤差,來(lái)確定稱重傳感器準(zhǔn)確度等級(jí),分別用0.02、0.03、0.05表示。

光柵式傳感器利用光柵形成的莫爾條紋把角位移轉(zhuǎn)換成光電信號(hào)(圖2)。光柵有兩塊,一為固定光柵,另一為裝在表盤軸上的移動(dòng)光柵。加在承重臺(tái)上的被測(cè)物通過(guò)傳力杠桿系統(tǒng)使表盤軸旋轉(zhuǎn),帶動(dòng)移動(dòng)光柵轉(zhuǎn)動(dòng),使莫爾條紋也隨之移動(dòng)。利用光電管、轉(zhuǎn)換電路和顯示儀表,即可計(jì)算出移過(guò)的莫爾條紋數(shù)量,測(cè)出光柵轉(zhuǎn)動(dòng)角的大小,從而確定和讀出被測(cè)物質(zhì)量。
