Mini sensor
The mini sensor is the smallest sensor for continuous fill-level monitoring and functions in accordance with the Reed chain principle. It is particularly suited for use in confined spaces and with small containers. Using very small floats, measurements can be carried out practically to the bottom of the container. Reed Electronics has a large range of materials and components and will find the right solution for your application.
The tried-and-tested miniature sensors are used, for example, to measure residual fluids in analytical instruments or in the chemicals industry, meaning that a process can be automated and optimised.
