The JUMO MAERA S29 SW level probe is used for the continuous hydrostatic level measurement in liquids. Filling heights between 1 mWS and 100 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.
