相关术语
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。
