压力开关的防护标准
NEMA防护等级是美国电气制造商协会工业控制装置和系统中的外壳防护标准。NEMA的防护标准除了防尘、防水之外，还包括防爆(IP代码只包括防尘和防水)。
NEMA 4X ：（水封、尘封、防腐蚀、室内或室外用外壳）：计划用于室内或室外，主要为了提供一定程度的保护，以防止腐蚀、飞扬粉尘和雨水、溅水、软管引出水、以及由于外部结冰引起的破坏。
NEMA 4X 相当于IP66 二者有什么区别？
NEMA 7X、NENA 9X（J120系列，针对于防爆开关）
压力开关定义
压力：垂直作用于流体或固体界面单位面积上的力。
差压：差压是指2个或多个压力点之间的压强的相对差值
表压（相对压力）：***压力与周围大气压的差值
绝压：以***零压为基准的压力值
压力开关：测量介质的压力，并进行反馈输出和控制的机械装置
***压力=表压力+大气压力
***压力=大气压力-真空压力
