BALLUFF位移開(kai)關型號:BTL5-C10-M1500-P-S32 BALLUFF位移開(kai)關對環境的要求條件較低。當被測(ce)對象(xiang)(xiang)是導電(dian)物(wu)體或可以(yi)固定(ding)在塊金屬物(wu)上的物(wu)體時，般都選(xuan)用渦(wo)流式接近開(kai)關，因(yin)為它的響應頻率高、抗(kang)環境干(gan)擾好(hao)、應用范圍廣、價格較低。若所測(ce)對象(xiang)(xiang)是非金屬（或金屬）、液位高度、粉狀物(wu)高度、塑料(liao)、煙草等。則應選(xuan)用電(dian)容(rong)式接近開(kai)關。這種開(kai)關的響應頻率低，但(dan)穩定(ding)性好(hao)。安裝時應考慮環境因(yin)素的影響。

BALLUFF位(wei)(wei)(wei)(wei)(wei)移(yi)(yi)傳感器(qi)(qi)(qi)(qi)型(xing)號:BES516-326-EO-C-03 BALLUFF位(wei)(wei)(wei)(wei)(wei)移(yi)(yi)傳感器(qi)(qi)(qi)(qi)它通過電(dian)(dian)位(wei)(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)元件(jian)將機械位(wei)(wei)(wei)(wei)(wei)移(yi)(yi)轉換成與之成線(xian)性(xing)或任意函數(shu)關系(xi)的(de)電(dian)(dian)阻(zu)或電(dian)(dian)壓輸出。普(pu)通直線(xian)電(dian)(dian)位(wei)(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)和圓形電(dian)(dian)位(wei)(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)都可(ke)(ke)分別用(yong)作(zuo)直線(xian)位(wei)(wei)(wei)(wei)(wei)移(yi)(yi)和角位(wei)(wei)(wei)(wei)(wei)移(yi)(yi)傳感器(qi)(qi)(qi)(qi)。但是，為實現測量(liang)位(wei)(wei)(wei)(wei)(wei)移(yi)(yi)目的(de)而設計的(de)電(dian)(dian)位(wei)(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)，要求在位(wei)(wei)(wei)(wei)(wei)移(yi)(yi)變化(hua)和電(dian)(dian)阻(zu)變化(hua)之間有個確(que)定關系(xi)。圖1中的(de)電(dian)(dian)位(wei)(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)式(shi)位(wei)(wei)(wei)(wei)(wei)移(yi)(yi)傳感器(qi)(qi)(qi)(qi)的(de)可(ke)(ke)動電(dian)(dian)刷與被(bei)測物(wu)體(ti)相連(lian)。物(wu)體(ti)的(de)位(wei)(wei)(wei)(wei)(wei)移(yi)(yi)引(yin)起電(dian)(dian)位(wei)(wei)(wei)(wei)(wei)器(qi)(qi)(qi)(qi)移(yi)(yi)動端的(de)電(dian)(dian)阻(zu)變化(hua)。

BALLUFF接近(jin)開關(guan)型(xing)號:BES M12MI-PSC20B BALLUFF接近(jin)開關(guan)屬于種(zhong)有開關(guan)量輸出的位置傳感器(qi)，它(ta)由LC高頻(pin)振(zhen)蕩器(qi)和放大(da)處理電路(lu)(lu)組(zu)成，利用金屬物(wu)體在接近(jin)這(zhe)個能(neng)產生(sheng)電磁場的振(zhen)蕩感應(ying)頭時，使物(wu)體內部產生(sheng)渦(wo)流(liu)。這(zhe)個渦(wo)流(liu)反(fan)作用于接近(jin)開關(guan)，使接近(jin)開關(guan)振(zhen)蕩能(neng)力衰減，內部電路(lu)(lu)的參數發生(sheng)變化，由此識(shi)別出有無金屬物(wu)體接近(jin)，進而控制開關(guan)的通或斷。這(zhe)種(zhong)接近(jin)開關(guan)所能(neng)檢測(ce)的物(wu)體必須是金屬物(wu)體。
