隔膜壓力開關的相關知識
隔膜壓力開關是隔膜元件與壓力開關組成的壓力測量產品，鑒于其內部的特殊結構，隔膜壓力開關與普通壓力開關相比，適應性比普通壓力開關更強，應用領域更加廣泛。
1.隔膜壓力開關的隔膜元件在介質的影響比較容易變形，隨后內部的密封液會受壓，形成一種壓力，將此種壓力傳到壓力開關中，因此，隔膜壓力開關可以測量帶黏度、帶結晶及帶腐蝕性的介質，因為其可以避免與被測介質的直接接觸。
2.安裝時，如果隔膜壓力開關受到的壓力與其所處的位置不符，可能其內部的液體會形成一個差壓，就會比較容易導致測量誤差，因此，用戶在安裝隔膜壓力開關時務必要多加注意。
3.由于隔膜壓力開關可能會經常測量一些性質較為惡劣的介質，所以，隔膜壓力開關的保養也要引起用戶的重視，每次使用完隔膜壓力開關之后，都要進行全面清理。
