GBS02, Water Level/Well Probe, Tank Contents Probe
GBS02, Water Level/Well Probe, Tank Contents ProbeFor measuring the level of fuel and other aggressive media.
The sensor is highly precise, insensitive to lateral flow and offers optionally lightning protection and other output signals (e.g. 0-10V).
For measuring of gasoline please order ex-design (option).
Piezoresistive pressure sensor with temperature compensation.
Welded, non-corrosive design with integral and additionally sealed water-proof connecting cable.
The pressure compensation is done via a cable-integrated air path to the atmosphere. Possible cable lengths up to 300m.
A special feature is the lateral flow resistance, which prevents media ingress. Therefore only the cable has to be replaced in case of a corresponding defect, while sensor is still unharmed.
