抽水馬達無水自動斷電的選擇
Oct 28th 2013, 14:59

最近想換家裡的抽水馬達，想要順便裝一下停水時可以讓馬達自動斷電的裝置，
上網找了一下發現大概有幾種選擇，
1.在在馬達的泵上安裝溫度保護開關，算便宜，似乎只要改配線就可以，不過不確定它的保護和解除方式是怎麼作。
2.黑鼠自動斷電器，感應水壓作動的，yahoo知識家有人提供說明書，感覺還蠻不錯的，可以是要改水管(頭痛)
3.最後一個是普誠的無水自動斷電器，看了一下討論好像是利用水的導電的特性來做感應，探棒有導電就通，沒導電就斷電，只要換一下入水端的墊片就可以用的樣子，這感覺蠻簡單的，不過完全沒看到有人在討論他的線組怎麼接，相關的資料也很少。

不知道大家家中的馬達有沒有裝這些東西，好不好用呢，會不會裝了反而更糟?

還是其實可以不必裝?
