900B01-0101實(shí)際使用時(shí),般只用額定量程的2/3~1/3。
(2)允許使用負(fù)荷(或稱(chēng)安全過(guò)載):傳感器允許施加的大軸向負(fù)荷。允許在定范圍內(nèi)超負(fù)荷作。般為120%~150%。
(3)限負(fù)荷(或稱(chēng)限過(guò)載):傳感器能承受的不使其喪失作能力的大軸向負(fù)荷。意即當(dāng)作超過(guò)此值時(shí),傳感器將會(huì)受到損壞。
(4)靈敏度: 輸出增量與所加的負(fù)荷增量之比。通常每輸入1V電壓時(shí)額定輸出的mV。本公司產(chǎn)品與其它公司產(chǎn)品配套時(shí),其靈敏系數(shù)必須。
(5)非線性: 這是表征此傳感器輸出的電壓信號(hào)與負(fù)荷之間對(duì)應(yīng)關(guān)系的確程度的參數(shù)。
(6)重復(fù)性: 重復(fù)性表征傳感器在同負(fù)荷在同樣條件下反復(fù)施加時(shí),其輸出值是否能重復(fù),這項(xiàng)特性更重要,更能反映傳感器的品質(zhì)。國(guó)標(biāo)對(duì)重復(fù)性的誤差的表述:重復(fù)性誤差可與非線性同時(shí)測(cè)定。傳感器的重復(fù)性誤差(R)按下式計(jì)算:R=ΔθR/θn×。ΔθR -- 同試驗(yàn)點(diǎn)上3次測(cè)量的實(shí)際輸出信號(hào)值之間的大差值(mv)。
