Float Switch Water Level Control Sensor with 10' Cable. Switch comes equipped with a generous 10-foot cord and adjustable counterweight, inside a robust enclosure Protection Degree. Whether you need to fill a container or empty a basement, this water level meter has got you covered dual function operation. Also, the float switches are rounded so that they don't get caught on any floating solids. Made of Plastic and Metal.. Commonly used in sump and condensate pumps. Used for sensing the level of liquid in the tank, controlling the pump, the indicator, the alarm, or other devices. Regulates water level measurements in electrically conductive liquids in gauge pipes, groundwater wells, sinks, barrels and tanks. Long-term observations for periodic measurement checks. Continuous water level detection during pumping tests. Exploration of well depths with the bottom sensor.. SIMPLE CONNECTION AND EASY TO USE - This compact, horizontally mounted float switch device can be placed at the top or the bottom of the tank. The plug has a 10 feet cable with an adjustable counterweight that accommodates most uses. As the liquid level reaches the upper or lower switching valve, the controller contact will send out a signal. The float switch can be used for an in-let flow of water and out-let flow of water from the tank to controlled the level of water, it works in both ways.. HIGH ACCURACY AND STABLE WORKING PERFORMANCE - BRODY float switch features high-quality BRODY-manufactured switches inside a robust enclosure. They also have short actuation lengths, which means you have reliable switching no matter how much slack you give the switch. No annoying components or brackets when cranking. Does not contain mercury. Non-toxic type, can be used in houses or factories.Can work with any kind of pump, sump pumps, sewage pumps , centrifugal pumps, etc..

13 Amps maximum pump run current. 85 Amps maximum pump start current. 7 to 36 adjustable pumping range. Wide angle design allows the float switch to operate over a range of approximately 70 to 90. UL Recognized for use in water and sewage.

Max Switching Voltage DC100V Max Switching Power 10W Float Ball Size 26x26mm Wire Length 350mm Screw M10. The float switch can be installed at the top or bottom of the tank, depending on whether you want to detect water rising or falling.. Floating ball switch is a kind of liquid level control device with simple structure and convenient use. It has the advantages of small volume and long working life compared with general mechanical switch. When selecting the right material, any kind of liquid, pressure and temperature can be used.. Widely Applications For tank pump water level controlFor fish tank and aquarium system Used for water level control of household appliancesUsed for water level control of swimming pool, fountain, pond, etc.. Please Note Float switch can not directly control solenoid valve or high power relay, AC contactor, etc. Small relays are required to transition..

Float switch with screw-in bushing side-mounts to a closed-tank to activate a condensate or other pump. NEMA 1 enclosure protection for use with water, hydraulic oils, and corrosive fluids. Float is positioned on the right at 45 degrees. Contacts open on liquid rise.

Total Length 115mm 4.53 Float Ball SizeApprox 24 x 23.7mm 0.94 x 0.93 LD Thread DiaApprox 10mm 0.39 Cable Length 40cm 15.7. Max Switching VoltageCurrent 110V DC0.5A. HOW TO WORK - By using a magnet to sense the reed switch. Float switch is mainly composed of a magnetic spring switch and a float. There are magnetic materials in the float. When the float moves up and down with the water level, it will touch the magnetic spring switch to detect the liquid position. WIDELY APPLICATION - Float switch can be used for water heating equipment such as water dispenser, water heater, humidifier, etc. It also can be used for water tower, drainage pool, water tank, culture pond, etc. PLEASE NOTE - Because the current that the switch can carry is much little0.5A, you must use a relay or contactor when it is connected by a load, relay or contactor are not included here..
