力士樂REXROTH壓力傳感器/力士樂電磁閥
REXROTH壓力傳感器從機(jī)械接收原理來說，是一個(gè)位移傳感器，由于在機(jī)電變換原理中應(yīng)用的是電磁感應(yīng)電律，其產(chǎn)生的電動勢同被測振動速度成正比，所以它實(shí)際上是一個(gè)速度傳感器。
REXROTH壓力傳感器是一種相對式非接觸式傳感器，它是通過傳感器端部與被測物體之間的距離變化來測量物體的振動位移或幅值的。電渦流傳感器具有頻率范圍寬（0～10 kHZ），線性工作范圍大、靈敏度高以及非接觸式測量等優(yōu)點(diǎn)，主要應(yīng)用于靜位移的測量、振動位移的測量、旋轉(zhuǎn)機(jī)械中監(jiān)測轉(zhuǎn)軸的振動測量。依據(jù)REXROTH壓力傳感器的相對式機(jī)械接收原理，電感式傳感器能把被測的機(jī)械振動參數(shù)的變化轉(zhuǎn)換成為電參量信號的變化。因此，電感傳感器有二種形式，一是可變間隙，二是可變導(dǎo)磁面積。

REXROTH壓力傳感器一般分為兩種類型。即可變間隙式和可變公共面積式。可變間隙式可以測量直線振動的位移。可變面積式可以測量扭轉(zhuǎn)振動的角位移。
REXROTH壓力傳感器由固定部分、可動部分以及支承彈簧部分所組成。為了使傳感器工作在位移傳感器狀態(tài)，其可動部分的質(zhì)量應(yīng)該足夠的大，而支承彈簧的剛度應(yīng)該足夠的小，也就是讓傳感器具有足夠低的固有頻率。 根據(jù)電磁感應(yīng)定律，感應(yīng)電動勢為：u=Blx&r 式中B為磁通密度，l為線圈在磁場內(nèi)的有效長度， r x&為線圈在磁場中的相對速度。 從傳感器的結(jié)構(gòu)上來說，慣性式電動傳感器是一個(gè)位移傳感器。然而由于其輸出的電信號是由電磁感應(yīng)產(chǎn)生，根據(jù)電磁感應(yīng)電律，當(dāng)線圈在磁場中作相對運(yùn)動時(shí)，所感生的電動勢與線圈切割磁力線的速度成正比。因此就傳感器的輸出信號來說，感應(yīng)電動勢是同被測振動速度成正比的，所以它實(shí)際上是一個(gè)速度傳感器。
