style="text-indent:25px">料位開關(guān)在安裝時應(yīng)該注意哪些事項(xiàng)呢？　一、在安裝之前，首先要確認(rèn)料位開關(guān)型號是否滿足現(xiàn)場的環(huán)境要求，如：過程壓力、過程溫度、介質(zhì)的化學(xué)性能等，確保料位開關(guān)在安裝后能夠正常使用。二、安裝前要確認(rèn)電源電壓是否與標(biāo)識上面的電壓一致。三、為了保證人身安全和避免損壞料位開關(guān)，應(yīng)在斷電的情況下接線。四、安裝時盡量避開進(jìn)料。五、為了確保測量的準(zhǔn)確性，可以將料位開關(guān)水平安裝。如果測量誤差允許在幾厘米范圍內(nèi)，建議將料位開關(guān)向下傾斜約20°后安裝，這樣可以減少由于物料在探頭上的掛粘而造成的測量誤差。當(dāng)用于測量快速升降和快速流動的物料時，還需要增加防護(hù)擋板，料位開關(guān)才能更可靠工作。音叉液位開關(guān)一般長度只有40mm。</p><div
