Description
The EFQS-HM180 automatic float level switch is a high-temperature resistant liquid level controller designed for reliable operation in demanding environments. Compared with standard micro switch versions, it adopts a mercury switch that withstands temperatures up to 180°C while maintaining excellent stability and switching accuracy. The device features a 304 stainless steel housing and high-temperature resistant silicone cable, ensuring reliable performance under extreme heat, humidity, and corrosive conditions.
With its built-in mercury contact design, the EFQS-HM180 provides precise switching operation without mechanical wear, supporting long-term continuous use. It is widely used in tanks, wells, and industrial liquid control systems for water, oil, and weak chemical liquids, making it especially suitable for high-temperature applications such as boilers, heating systems, and other demanding industrial environments.

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.
