T/LL70 Vertical Float Switch
Vertical magnet and reed type float switch with up to 6 switch points and many custom build options.
The T/LL70 series is a comprehensive range of vertical float level switches designed around the proven and reliable magnet and reed switch principle.
Comprising many build variants, the T/LL70 is customized to each application by means of materials, level adjustment, connection, thread and reed contact specification etc. The data below gives some sense of the numerous combinations, but some interdependency exists with regard to the materials of construction.
Liquids compatible with the construction materials; typically diesel, kerosene, petrol, water.
