Water Float Sensor P 43 - Simple Water Level Indicator ( Water Level Sensor Float Switch P43 )

Description

A Float sensor defines as a simple water level indicator. This water level controller used in a pump, an indicator, an alarm, or other devices. A water level controller is actually a Magnetic float sensor with an electromagnetic ON/OFF switch that floats on top of a liquid surface. The float switch is to open or close a circuit as the liquid level rises or falls. Float switches are “normally closed, condition indicates that the two wires from the top of the switch form a complete circuit. This float sensor consists of a magnetic reed switch to open or close the circuit. The reed switch is designed to enclosed in a glass tube, cemented into a plastic or stainless steel stem with epoxy. When the magnet comes in contact with each other allowing the current to pass through. As soon as the magnet moved away, the contacts demagnetize and separate, thus breaks the circuit, The float switch installations reduce the chance for the accumulation of dirt on the float that would prevent its motion. Therefore these Float switch materials designed to resist the deleterious effects of corrosive process liquids. In most of the systems, a properly selected and sized float detects the interface level between two liquids of different densities. Moreover, the liquid with high viscosity cannot be measured. In case if the pressure inside of the tank is high or the liquid’s specific gravity is low, the float will not operate. So these conditions not permitted for liquid level detection. Normally the float sensor failure occurs due to overloading, frequently caused by spiking voltage.
