A float level sensor is a type of device used to measure the level of liquid within a container or tank. It operates on a simple principle: as the liquid level rises or falls, a float attached to the sensor moves accordingly. This movement is then translated into an electrical signal or mechanical action, providing a measurement of the liquid level.
Here's a brief description of how a float level sensor typically works:
Float: The sensor contains a buoyant float, usually made of a material such as plastic or stainless steel, which floats on the surface of the liquid. The float is designed to move up and down with changes in the liquid level.
Mechanical Linkage: The float is connected to a mechanical linkage or shaft within the sensor housing. As the liquid level changes, the float moves the linkage or shaft accordingly.
Sensor Element: Inside the sensor housing, there is a sensing element that detects the movement of the float. This sensing element can vary depending on the type of sensor and its technology. It could be a mechanical switch, reed switch, magnetic sensor, or other types of transducers.
Output Signal: The movement of the float is converted into an electrical signal or mechanical action by the sensing element. This signal is then transmitted to a display, control system, or other monitoring devices for further processing or action.
Float level sensors are commonly used in various industries for liquid level measurement and control purposes, including in tanks for water, fuel, chemicals, and more. They are relatively simple, reliable, and cost-effective solutions for monitoring liquid levels in industrial and commercial applications.
