Aigend Water Level Sensor, Double Float Ball Stainless Steel Liquid Level Sensor Float Switch Vertical Water Level Sensor for Tank Pool Sinks, Fish Tanks (Floating body 250mm)

• 【Multi-Purpose】: The professionally manufactured double-ball float switch can not only be used to control the water level (drainage or water) of water tanks, swimming pools, sinks, fish tanks, etc., but can also be used as upper and lower liquid level alarm switches.
• 【Use】: The water level sensor is simple and easy to operate. The normal water inflow process is started and started by the bottom float switch, and the top float switch stops working. Drainage is started by the float switch at the top and stopped by the float switch at the bottom.
• 【Flexible】: The stainless steel double float switch has an operating range of 10mm. If a larger control range is required, a combination of two float switches can be used, which will have a large stroke, ensuring that the pump does not start frequently, saving time and improving efficiency.
• 【Accurate】: The internal contacts of the vertical water level controller sensor include a reed switch with extremely high sensitivity, high resistance and cost-effectiveness. The stainless steel liquid level sensor responds quickly and has high precision, making the control more accurate and timely to meet the needs of different projects.
• 【Practical】: The double-ball liquid level sensor is light in weight and small in size. The float switch is easy to store and maintain, and supports long-term stable use. If you need to directly control the solenoid valve or high-power relay, AC contactor, etc., you need a small relay ( Such as HH54P) for transition.

Features: The float switch cannot directly control solenoid valves or high-power relays, AC contactors, etc.A small relay(like HH54P) is needed for transition. The double float switch can be used to control the liquid level of the water tank, pool, sink, fish tank, etc. (drain or water), or to make the upper and lower alarm switch of the liquid level. The contacts inside are made of a reed switch with very high sensitivity. The action range of the two floats of the double float switch is 10 mm. If the demand control range is large, two float switch combinations can be used, so that there is a large stroke to ensure that the pump does not start frequently. Normal water intake process activated by the float switch below, and the float switch above stops working. The drain is activated by the float switch above and the lower float switch stops working.
