FLOWLINE音叉液位開關(guān)震動(dòng)頻率為400Hz,開關(guān)進(jìn)入液體或者懸浮介質(zhì)時(shí),音叉液位開關(guān)頻率將要發(fā)生變化。測量的頻率變化達(dá)到一定時(shí),繼電器變化狀態(tài)指明介質(zhì)情況。音叉液位開關(guān)主要應(yīng)用于有結(jié)層、有雜質(zhì)的污水和鹽酸、氫氧化鈉等工業(yè)用液體。FLOWLINE音叉液位開關(guān)產(chǎn)品特點(diǎn):
● 可應(yīng)用在無危險(xiǎn)重量輕的固體包括顆粒和粉末物
● 繼電器FET開關(guān)輸出可與PLC、SCADA或報(bào)警器相接
● PP/Ryton材料的塑料結(jié)構(gòu)使音叉液位開關(guān)具有防腐蝕性
● IP68 或NEMA6的探頭和纜可用于罐或槽中的液下操作
