Float and Level Switches

Monitoring and control of liquid, powder, or granulated material levels and residual volume are required in factories, plants, various equipment, rivers, and utility water tanks. Level switches and level metres detect and measure commodities such as liquids, powders, and granular particles in tanks, containers, and pipes.

The switch detects the electrical difference between empty and full containers of material to determine the amount. When the material is empty, the detecting and grounding electrodes' electrical states are as follows: resistance (Ro) is infinite, and capacitance (Co) is a specific capacitance value specified by the installation status.

A level switch is a kind of sensor that detects liquids, powders, or grains in a specific location, and it is sometimes referred to as a level sensor.

When a tank is full of fluid, for example, it will overflow, a level switch is installed at the tank's top to prevent overflow. When the liquid makes contact with the level switch, a signal is sent to prevent the liquid from overflowing the tank. (The identification of the presence of a substance in a tank is known as full detection or upper limit detection.) 

On the other hand, a level switch is used to keep the tank from being completely emptied when the liquid level falls as it is released. This is referred to as a lower limit or empty detection.

Manufacturing facilities are using a wide variety of sensors as they put a greater emphasis on energy saving. Level sensors are used in challenging environments with high temperatures, pressures, vibration, and surroundings. 

Level sensors detect a wide range of objects. Under these conditions, level sensors must be very reliable. Our level sensors meet these requirements. They are created with a high level of skill and technological knowledge.
