Motion Sensors正交輸出雙通道速度傳感器–HD系列

HD系列正交輸出傳感器基于霍爾效應(yīng)傳感器技術(shù),可以感應(yīng)目標(biāo)運(yùn)動(dòng)從真零到15KHz的變化。HD系列提供雙通道輸出,并在需要時(shí)提供定向邏輯。HD傳感器的輸出頻率具有方形脈沖波形(數(shù)字),該波形與已感測(cè)到的渦輪葉片、輪齒等的數(shù)量直接相關(guān)。這些脈沖反過(guò)來(lái)可以相互關(guān)聯(lián)以確定流速、RPM或速度。

HD傳感器基于H系列,該系列在傳感器中包含一個(gè)磁鐵,使其能夠感應(yīng)黑色金屬和磁鐵目標(biāo)。最大氣隙感應(yīng)距離通常為0.100〃,這些傳感器可以進(jìn)行優(yōu)化,以檢測(cè)精細(xì)和大間距目標(biāo)

HD系列傳感器由兩個(gè)霍爾效應(yīng)元件組成,用磁鐵偏置,以檢測(cè)鐵靶齒輪旋轉(zhuǎn)引起的磁場(chǎng)強(qiáng)度變化。當(dāng)目標(biāo)檔位經(jīng)過(guò)傳感器元件A時(shí),輸出以目標(biāo)檔位的一半節(jié)距(P/2)從邏輯0切換到邏輯1。隨著目標(biāo)檔位的繼續(xù),輸出在齒輪節(jié)距(P)處從邏輯1切換到邏輯0。

傳感器元件B與元件a的間距為目標(biāo)齒輪節(jié)距(P/4)的四分之一。元件B的輸出與元件a輸出的偏移量為四分之一(P/4)。在電氣方面,這會(huì)產(chǎn)生90°的相移。當(dāng)齒輪沿逆時(shí)針?lè)较蜣D(zhuǎn)動(dòng)時(shí),輸出A領(lǐng)先輸出B。當(dāng)齒輪沿順時(shí)針?lè)较蜣D(zhuǎn)動(dòng),輸出A落后于輸出B。以上描述只是解釋HD系列傳感器的基本操作的理論理想模型。物理世界的現(xiàn)實(shí),如機(jī)械公差、磁場(chǎng)變化和其他物理現(xiàn)象,會(huì)導(dǎo)致與理想模型的偏差。

方向

為了獲得最佳性能,需要將傳感器與目標(biāo)旋轉(zhuǎn)對(duì)齊,以確保霍爾效應(yīng)元件與磁場(chǎng)的正確定向

我們的Quadrature傳感器采用12節(jié)距齒輪進(jìn)行校準(zhǔn)和測(cè)試。傳感器殼體上的對(duì)準(zhǔn)標(biāo)記基于12變槳齒輪。如果使用具有不同節(jié)距的齒輪,則對(duì)準(zhǔn)標(biāo)記應(yīng)僅用作起點(diǎn),并且應(yīng)在安裝過(guò)程中旋轉(zhuǎn)傳感器,同時(shí)監(jiān)測(cè)輸出,以獲得正確的正交信號(hào)。
