傳感器的靜態(tài)特性是指對(duì)靜態(tài)的輸入信號(hào)，傳感器的輸出量與輸入量之間所具有相互關(guān)系。因?yàn)檫@時(shí)輸入量和輸出量都和時(shí)間無(wú)關(guān)，所以它們之間的關(guān)系，即傳感器的靜態(tài)特性可用一個(gè)不含時(shí)間變量的代數(shù)方程，或以輸入量作橫坐標(biāo)，把與其對(duì)應(yīng)的輸出量作縱坐標(biāo)而畫(huà)出的特性曲線來(lái)描述。表征傳感器靜態(tài)特性的主要參數(shù)有：線性度、靈敏度、遲滯、重復(fù)性、漂移等。WT100-N1419 WT100-P3419 WT100-P4419 WT100-N1419 WT100-N3419 WT100-N4419 WT100-N1412 WT100-P1439 WT100-P3439 WT100-P4439 WT100-N1439 WT100-N3439 WT100-N4439 WT100-N1432 WT100-P1432 WT100-P1412 WL100-P14396 WL100-P3439 WL100-P4439 WL100-N1439 WL100-N3439 WL100-N4439 WL100-P1239 WL100-P1339 WL100-P3239 WL100-P3339 WL100-P4239 WL100-P4339 WL100-N1239 WL100-N1339 WL100-N3239 WL100-N3339 WL100-N4239 WL100-N4339 WL100-P1429 WL100-P3429 WL100-P4429 WL100-N1429 WL100-N3429 WL100-N4429 WS100-P1439 WE100-P1439/WE100-P1439 WS100-P3439/WE100-P3439 WS100-P4439/WE100-P4439 WS100-N1439/WE100-N1439 WS100-N3439/WE100-N3439 WS100-N4439/WE100-N4439 WS100-P1239/WE100-P1239 WS100-P1339/WE100-P1339 WS100-P3239/WE100-P3239 WS100-P3339/WE100-P3339 WS100-P4239/WE100-P4239 WS100-P3339/WE100-P4339 WS100-N1239/WE100-N1239 WS100-N1339/WE100-N1339 WS100-N3239/WE100-N3239 WS100-N3339
?。?）線性度：指?jìng)鞲衅鬏敵隽颗c輸入量之間的實(shí)際關(guān)系曲線偏離擬合直線的程度。定義為在全量程范圍內(nèi)實(shí)際特性曲線與擬合直線之間的最大偏差值與滿量程輸出值之比。

?。?）遲滯：傳感器在輸入量由小到大（正行程）及輸入量由大到小（反行程）變化期間其輸入輸出特性曲線不重合的現(xiàn)象成為遲滯。對(duì)于同一大小的輸入信號(hào)，傳感器的正反行程輸出信號(hào)大小不相等，這個(gè)差值稱(chēng)為遲滯差值。
?。?）重復(fù)性：重復(fù)性是指?jìng)鞲衅髟谳斎肓堪赐环较蜃魅砍踢B續(xù)多次變化時(shí)，所得特性曲線不一致的程度。
?。?）漂移：傳感器的漂移是指在輸入量不變的情況下，傳感器輸出量隨著時(shí)間變化，次現(xiàn)象稱(chēng)為漂移。產(chǎn)生漂移的原因有兩個(gè)方面：一是傳感器自身結(jié)構(gòu)參數(shù)；二是周?chē)h(huán)境（如溫度、濕度等）。
傳感器動(dòng)態(tài)特性
所謂動(dòng)態(tài)特性，是指?jìng)鞲衅髟谳斎胱兓瘯r(shí)，它的輸出的特性。在實(shí)際工作中，傳感器的動(dòng)態(tài)特性常用它對(duì)某些標(biāo)準(zhǔn)輸入信號(hào)的響應(yīng)來(lái)表示。這是因?yàn)閭鞲衅鲗?duì)標(biāo)準(zhǔn)輸入信號(hào)的響應(yīng)容易用實(shí)驗(yàn)方法求得，并且它對(duì)標(biāo)準(zhǔn)輸入信號(hào)的響應(yīng)與它對(duì)任意輸入信號(hào)的響應(yīng)之間存在一定的關(guān)系，往往知道了前者就能推定后者。最常用的標(biāo)準(zhǔn)輸入信號(hào)有階躍信號(hào)和正弦信號(hào)兩種，所以傳感器的動(dòng)態(tài)特性也常用階躍響應(yīng)和頻率響應(yīng)來(lái)表示。WT100-N1419 WT100-P3419 WT100-P4419 WT100-N1419 WT100-N3419 WT100-N4419 WT100-N1412 WT100-P1439 WT100-P3439 WT100-P4439 WT100-N1439 WT100-N3439 WT100-N4439 WT100-N1432 WT100-P1432 WT100-P1412 WL100-P14396 WL100-P3439 WL100-P4439 WL100-N1439 WL100-N3439 WL100-N4439 WL100-P1239 WL100-P1339 WL100-P3239 WL100-P3339 WL100-P4239 WL100-P4339 WL100-N1239 WL100-N1339 WL100-N3239 WL100-N3339 WL100-N4239 WL100-N4339 WL100-P1429 WL100-P3429 WL100-P4429 WL100-N1429 WL100-N3429 WL100-N4429 WS100-P1439 WE100-P1439/WE100-P1439 WS100-P3439/WE100-P3439 WS100-P4439/WE100-P4439 WS100-N1439/WE100-N1439 WS100-N3439/WE100-N3439 WS100-N4439/WE100-N4439 WS100-P1239/WE100-P1239 WS100-P1339/WE100-P1339 WS100-P3239/WE100-P3239 WS100-P3339/WE100-P3339 WS100-P4239/WE100-P4239 WS100-P3339/WE100-P4339 WS100-N1239/WE100-N1239 WS100-N1339/WE100-N1339 WS100-N3239/WE100-N3239 WS100-N3339WT100-N1419 WT100-P3419 WT100-P4419 WT100-N1419 WT100-N3419 WT100-N4419 WT100-N1412 WT100-P1439 WT100-P3439 WT100-P4439 WT100-N1439 WT100-N3439 WT100-N4439 WT100-N1432 WT100-P1432 WT100-P1412 WL100-P14396 WL100-P3439 WL100-P4439 WL100-N1439 WL100-N3439 WL100-N4439 WL100-P1239 WL100-P1339 WL100-P3239 WL100-P3339 WL100-P4239 WL100-P4339 WL100-N1239 WL100-N1339 WL100-N3239 WL100-N3339 WL100-N4239 WL100-N4339 WL100-P1429 WL100-P3429 WL100-P4429 WL100-N1429 WL100-N3429 WL100-N4429 WS100-P1439 WE100-P1439/WE100-P1439 WS100-P3439/WE100-P3439 WS100-P4439/WE100-P4439 WS100-N1439/WE100-N1439 WS100-N3439/WE100-N3439 WS100-N4439/WE100-N4439 WS100-P1239/WE100-P1239 WS100-P1339/WE100-P1339 WS100-P3239/WE100-P3239 WS100-P3339/WE100-P3339 WS100-P4239/WE100-P4239 WS100-P3339/WE100-P4339 WS100-N1239/WE100-N1239 WS100-N1339/WE100-N1339 WS100-N3239/WE100-N3239 WS100-N3339
靈敏度是指?jìng)鞲衅髟诜€(wěn)態(tài)工作情況下輸出量變化△y對(duì)輸入量變化△x的比值。
它是輸出一輸入特性曲線的斜率。如果傳感器的輸出和輸入之間顯線性關(guān)系，則靈敏度S是一個(gè)常數(shù)。否則，它將隨輸入量的變化而變化。
靈敏度的量綱是輸出、輸入量的量綱之比。例如，某位移傳感器，在位移變化1mm時(shí)，輸出電壓變化為200mV，則其靈敏度應(yīng)表示為200mV/mm。
當(dāng)傳感器的輸出、輸入量的量綱相同時(shí)，靈敏度可理解為放大倍數(shù)。
