In today's highly technological world, level measurement in industrial plants, tanks, and containers is becoming increasingly important. Level measurement is a fundamental process in industry and significantly influences the efficiency and safety of operations. Analog level measurement using a reed chain has proven to be a true leader in this field. It allows for continuous and precise monitoring of liquid levels.
Operating Principle
The operating principle of an analog level sensor with a reed chain in combination with a float is based on exploiting the up and down movement of a float within the liquid level. The level sensor consists of a reed chain and a float. The reed chain comprises multiple individual reed switches spaced at regular intervals along a flexible metal strip. Each reed switch consists of two ferromagnetic contacts separated from each other by a glass housing. In contrast, the float is a buoyant body that rests on the surface of the liquid and moves up and down according to the level. The float is equipped with a magnet, while the reed chain is vertically positioned inside the container. When the liquid level changes, and the float rises or falls, the magnet moves along the reed chain. The individual reed switches of the reed chain respond to the magnetic field of the float. Once the magnet approaches a reed switch, the contacts of the reed switch close, generating an electrical signal. This signal is then captured by a measuring device or evaluation unit and converted into a measurable value.
