如何找到壓力開關(guān)信號無輸出的根源
壓力開關(guān)沒有信號輸出一直困擾大家，遇到該問題時，很多客戶都無從下手，本期為大家詳細(xì)介紹遇到壓力開關(guān)無信號輸出時該怎么做。
1.檢查供電電源是否正常，電源是否有短路現(xiàn)象，如果都正常，那就要從壓力開關(guān)入手檢
2.檢查壓力開關(guān)的膜片是否損壞：輕壓開關(guān)的上下膜片是否有流動感，如果沒有，那就是膜片損壞，需要更換膜片。
3.檢查開關(guān)信號變送部分是否故障，如有則應(yīng)更換開關(guān)信號部件。
4.如果信號正常，計算機(jī)沒有顯示量程或者顯示滿量程，那就應(yīng)考慮電阻是否正常。
壓力開關(guān)在運行之前要確認(rèn)各接線接觸良好，無短路、斷路，否則很容易出現(xiàn)沒有信號輸出的情況。
