壓力開關類型的確定
想要確定一款壓力開關的類型，其實最主要的是要把該壓力開關的檢測元件即壓力傳感器確定下來，不過壓力傳感器的確定也是要經過多方面考慮之后才能確定的。下面小編就教大家如何確定壓力開關的類型。
由于壓力傳感器的種類有多種，膜片式壓力傳感器、膜盒式壓力傳感器、及波紋管式壓力傳感器等等，所以壓力開關也隨之有多種類型，所以具體應該根據被測介質的特點及周圍使用環境進行考慮。當被測介質中帶有腐蝕性介質、易結晶介質、帶黏度的介質等惡劣介質時，最好是選擇膜片式的壓力傳感器，這樣可以有效的避免腐蝕介質對壓力開關的損壞；當周圍環境中帶有易燃易爆風險時，那么最好選擇防爆型的壓力開關；當需測量的壓力帶有壓力差時，那么最好選擇差壓型壓力開關。以此類推，選出最適合的一款壓力開關。
