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）
系列号-型号 设定点可调范围 死区 ***大过压范围 耐压 压力接口 接液材料
精度：表示设备***程度的值，包括线性度、公差、迟滞、重复性等。目前长野的压力开关***高精度可达到±0.5%F.S，型号为CB33。
***大压力（Max.P）：压力范围的***大值。
满量程（F.S）：压力范围***大值和***小值的差值。
接断差（死区）：是指开关设定动作值和复位值的差值，例如当设定、值为1MPa，实际复位值为0.9MPa时，接断差为0.1MPa。
工作温度：是指仪器的内部机构、敏感元件等工作时不会发生持续变形的温度范围。一般压力开关推荐工作温度范围为-5~400C，若介质温度过高时，可考虑加附件虹吸管（灌状），达到降温的目的。
S.P.D.T（单刀双掷）：由一个常开、一个常闭触点和一个公共端构成。
D.P.D.T（双刀双掷）：由一个对称的左、右公共端，两组常开、常闭端子构成。
上限一接点（常开）：压力上升到设定值时，接点动作，回路导通。
下限一接点（常闭）：压力下降到设定值时，接点动作，回路导通。
