OVERVIEW
The JUMO MAERA S26 level probe is used for the continuous hydrostatic level measurement of liquids. Filling heights between 2.5 mWS and 25 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.
The surrounding pressure is realized using a special cable with an integrated pressure equalization hose. Any variations in air pressure are thereby automatically compensated for and the surrounding pressure is therefore taken into account.
The level probe is approved for use in drinking water.
