Submersible pressure sensors

Submersible pressure sensors from WIKA - market leader since 1946

The submersible pressure sensor 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.

What is the overpressure limit?

Pressures up to the overpressure limit will not cause any permanent damage to the measuring instrument, however, the error limits specified in the data sheet could be exceeded.

What causes zero-point drift?#

Zero-point drift, also called zero-point error, is caused by aging of the electrical components through temperature cycling and load cycling. See this blog for an overview of accuracy errors in pressure sensors.
