數(shù)字式儀表用數(shù)字顯示被側(cè)參數(shù)的量值,無論何人認讀,結(jié)果*一樣,克服了主觀誤差。需要記錄時,亦可打印出數(shù)字。這種優(yōu)點也常常被用到數(shù)據(jù)的自動化處理上。正是山于這種優(yōu)點,使它在側(cè)zui工作中受到歡迎?,F(xiàn)在數(shù)字式儀表已經(jīng)得到大力發(fā)展和推廣,廣泛使用于各類學(xué)科和國民經(jīng)濟部門。但是數(shù)字式儀表直觀性較差。
C 記錄式儀表
記錄式儀表的優(yōu)點是其側(cè)量值可以*保存?zhèn)洳?,并可避免因視讀和人工記錄造成的失誤。
經(jīng)典的記錄式儀表安裝在模擬式儀表內(nèi),它將被測參數(shù)模擬量的瞬時值,隨時間的推移,山記錄儀的記錄筆尖連續(xù)記錄在的記錄紙上,表現(xiàn)為被測參數(shù)隨時間變化的曲線形式。
數(shù)字式儀表一般可以直接接打印機,打印記錄數(shù)字結(jié)果?,F(xiàn)在數(shù)字式儀表亦可以先連接數(shù)模變換器,將數(shù)字zui轉(zhuǎn)換為模擬是,然后仍然可以用記錄儀描繪出被側(cè)參數(shù)隨時間變化的曲線。
還有一種x-y記錄儀,同樣屬于記錄式儀表。其特點是包含兩組輸人和自動記錄機構(gòu),可以記錄x、y兩組是之間的函數(shù)關(guān)系。輸入x值,使記錄筆尖沿導(dǎo)軌作上下移動。與此同時,輸人y值,使導(dǎo)軌作左右移動,從而筆尖所描繪的曲線正是x-y之間的函數(shù)關(guān)系。
