在一般的工業(yè)生產(chǎn)場(chǎng)所，通常都選用渦流式(電感式)接近開(kāi)關(guān)和電容式接近開(kāi)關(guān)。因?yàn)檫@兩種接近開(kāi)關(guān)對(duì)環(huán)境的要求條件較低。電感式、電容式、非機(jī)械磁性式和超聲波式接近開(kāi)關(guān)應(yīng)能在周?chē)h(huán)境溫度為-25°C～+70°C條件下動(dòng)作，在環(huán)境溫度允許范圍內(nèi)其動(dòng)作特性應(yīng)保持不變。但對(duì)于超聲波式接近開(kāi)關(guān)，由于聲速與空氣溫度有關(guān)，其動(dòng)作距離可能每度變化。光電式接近開(kāi)關(guān)應(yīng)能在-5°C～+55°C環(huán)境溫度下動(dòng)作，在環(huán)境溫度允許范圍內(nèi)其動(dòng)作特性應(yīng)保持不變。電感式接近開(kāi)關(guān)一般用以檢測(cè)各種金屬體，其響應(yīng)頻率高，抗環(huán)境干擾性能好，且價(jià)格較低，因此應(yīng)用范圍較廣;電容式接近開(kāi)關(guān)一般用以檢測(cè)各種導(dǎo)電或不導(dǎo)電的液體或固體，其響應(yīng)頻率低，但穩(wěn)定性好;利用光電效應(yīng)做成的光電式接近開(kāi)關(guān)，用以檢測(cè)所有不透光物質(zhì)且對(duì)使用環(huán)境的要求較高，一般用于環(huán)境條件較好，無(wú)粉塵污染的場(chǎng)合;利用多普勒效應(yīng)可制成超聲波接近開(kāi)關(guān)，用以檢測(cè)不透過(guò)超聲波的物質(zhì);利用霍爾元件做成的霍爾式接近開(kāi)關(guān)，其檢測(cè)對(duì)象必須是磁性物體，用與單方向檢測(cè)磁鐵或者磁鋼，且它的價(jià)格較低。無(wú)論選用哪種接近開(kāi)關(guān)，都應(yīng)注意對(duì)工作電壓、負(fù)載電流、響應(yīng)頻率、檢測(cè)距離等各項(xiàng)指標(biāo)的要求。4.接近開(kāi)關(guān)的標(biāo)準(zhǔn)簡(jiǎn)介目前。寧波圓形接近開(kāi)關(guān)原理南京接近開(kāi)關(guān)質(zhì)量哪家好，歡迎來(lái)電咨詢，無(wú)錫日環(huán)傳感科技有限公司。</p><div
