The new 298A tank level sensor expands the reed-based product family for level measurement in fuel, coolant, oil, water or chemical tanks. Designers and developers of machines, vehicles and systems benefit from the compact, flexibly configurable level sensor with analogue output signal.

Different process connections also offer a high degree of flexibility for the connection.

In addition to the standard tank sensors listed, we also offer customised solutions for your application – we will be happy to advise you.
