Product Details

The JUMO MAERA F27 – 404391 level probe is used for the continuous hydrostatic level measurement in liquids. Filling heights between 0.5 and 16 mWS (water column) can be achieved in ventilated tanks.

When the level probe is immersed into a liquid, a liquid column emerges above the probe. The liquid column increases as the probe is immersed deeper into the liquid and creates a hydrostatic pressure on the measuring system by the force of its weight. The measured pressure is transmitted as a standard signal. The signal is linearly proportional to the rising liquid column.

The surrounding pressure is achieved through a special cable with an integrated pressure equalization hose. Any variations in air pressure are therefore automatically compensated and the surrounding pressure is taken into account. The installation can be performed in both indoor and outdoor areas.

A variant with integrated overvoltage protection is available for outdoor installations, which protects the level probe against damage in the event of lightning strikes in surrounding water. The version with a PTFE case is suitable for applications in aggressive mediums. With regard to the temperature-dependent density of a liquid, the medium temperature can be recorded with an integrated temperature sensor Pt100 during level measurement. This temperature value is then used to compensate.

Further information on our level probes from the JUMO MAERA series can be found in the brochure “Level Probes – Hydrostatic Level and Filling Level Measurement” in the Documentation category.
