數(shù)字顯示，使得該系列產(chǎn)品能夠被用于各種工業(yè)場(chǎng)合，浙江接觸開關(guān)。3.雙鍵設(shè)計(jì)和用戶友好的菜單使產(chǎn)品使用更加方便。4.多種連接方式可以充分滿足各種特定的安裝需求。5.可330°旋轉(zhuǎn)的顯示頭能保證在不同安裝方式下獲得較佳觀察角度。6.適用于非結(jié)晶介質(zhì)。7，浙江接觸開關(guān)，浙江接觸開關(guān).可做高精度防堵塞型產(chǎn)品，可測(cè)量粘性介質(zhì)。8.可加裝特氟龍涂層的方式達(dá)到抗腐蝕的要求。電子壓力開關(guān)是一款不論是從外觀結(jié)構(gòu)還是使用性能方面都比機(jī)械壓力開關(guān)優(yōu)越的智能化開關(guān)。浙江接觸開關(guān)</p><div
