GBS01, Water Level Well Tank Contents Probe
GBS01, Water Level Well Tank Contents ProbeFor simple and inexpensive applications. Suitable for permanent level measuring in tanks, rivers, lakes, drinking-water wells, drilling holes and waste water plants.
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.
