The submersible pressure sensor, sometimes also referred to as a level probe, is a special type of pressure sensor for hydrostatic level measurement in tanks, wells, shafts and bore holes. For this, the submersible pressure sensor is submerged directly in the liquid to be measured, and positioned as close as possible to the bottom. There, the submersible pressure sensor measures the hydrostatic pressure, which enables a direct conclusion regarding the current level, i.e. the height of the liquid column above it.
