機械壓力開關的優缺點介紹
一、機械壓力開關的優點介紹
機械壓力開關相比電子壓力開關，由于內部是純機械結構，所以價格肯定是較為便宜的，并且機械壓力開關不需要供電的，使用起來簡單方便；機械壓力開關含有常開和常閉兩種觸點，壓力的報警點可以進行調節，機械壽命長，工作穩定。
二、機械壓力開關缺點介紹
機械壓力開關為純機械結構動作，都是通過機械形變來轉換開關量，故精度等級較低，一般都小于等于1.5%FS，雖然不用帶電操作，但是卻需要通過加壓達到指定壓力之后動作，且不可以設定滿量程，抗震性能也較差，因此如果是振動環境需要將機械壓力開關固定住之后方可使用。
機械壓力開關由于是較為傳統的壓力開關，還沒有跟上電子壓力開關的智能化步伐，不過也已經適用在石化、煉油、鉆井平臺等眾多工業場所了。
