配件
这款浮球开关是常开 (NO) 的还是常闭 (NC) 的？
通过在安装时将浮子方向翻转，可以将其配置为常开 (NO) 或常闭 (NC) 状态。
这款产品适用于哪些液体？
它适用于水、清洁液体以及与 PP 材质兼容的轻度腐蚀性介质。
它可以在高温环境下使用吗？
PP 浮球开关通常适用于中温环境；若用于高温环境，则建议选择不锈钢型号。
浮球开关是如何控制液位的？
浮子内含磁铁，随着液位的升降激活磁簧开关，从而为控制系统产生开/关 (ON/OFF) 信号。
安装复杂吗？
安装并不复杂。它采用简单的螺纹安装方式，可以轻松地安装在各种水箱或容器上。
PP 材质长期使用可靠吗？
是的。PP（聚丙烯）具有良好的耐化学性、低吸水率和稳定的性能，非常适合长期使用。

The EDPS series differential pressure switch is a special type of control switch. It is a kind of switch that controls closing or opening based on the pressure difference between mutual components and relies on electrical signals for information transmission.
Floats are available in 1–4 pieces (optional,or more), and the rod length can be customized.
Notes:Float switches cannot directly control solenoid valves, high-power relays, AC contactors, etc. A small relay HH45P is required for transition.
