Beneficio para el cliente

  • Process reliability

The core of the level probe is a piezoresistive titanium measuring cell, which features high overload resistance and which is particularly stable in the long term, reliable, and temperature-resistant. The version out of titanium also assures a high chemical resistance so that this version can be used in media containing chloride. Maximum security during startup is guaranteed by a reverse polarity protection that protects the measuring device against damages.

  • Permitted

The level probe is certified for the demands in shipbuilding and for offshore applications. In addition, it is also suitable for explosion proof areas.



Level and filling level measurement

  • In ballast tanks used in shipbuilding
  • In the wastewater industry
  • In splash water containers for swimming pool technology
  • In media containing chloride


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.
The measurement takes place without being influenced by medium properties or any foam formation. Approvals are available for the special requirements in shipbuilding and explosion protection. The cost-optimized titanium level probe with a front-flush membrane offers an alternative in highly viscous media. The screwable protective cap protects the membrane.
