<p>Device for level detection of fluid in a container, comprising a magnetic float (14) arranged around an extended main body (10), to which an electric current is applied. The main body (10) comprises a number of current strips (16a, 16b) and a magnetic band (22), arranged to be activated by the magnetic float (14), whereby contact is made between the electric current strips (16a, 16b) so that a closed circuit with a certain resistance characteristic is provided. In an alternative embodiment, the magnetic float and the magnetic band are not included, but the fluid pressure is used to force the current strips against each other.</p> |
