壓力開關測量特殊介質的注意事項
1.普通的壓力開關都只可以測量水、空氣、液壓油、潤滑油、輕燃油等中性介質，不可以測量腐蝕性、高黏度或有毒性的氣體和液體，當測量介質帶有腐蝕性質時，用戶需要選擇接口為不銹鋼材質的開關，以免介質對開關的元件產生腐蝕。
2.當測量介質為易揮發、含氣泡、含懸浮物、含固體顆粒物的液體或氣體時，任何壓力開關都不可以測量，除非一些經過特殊定制的開關。
3.對于那些需要連續測量壓力的工作場所，當被測介質的溫度、壓力會隨時存在較大波動時，應事先采取應對措施，以提高測量精度。
總結：壓力開關的型號、結構形式、接口材質的選擇、是否需要防爆等選用，都需要根據被測介質的特性等因素來確定。
