JUMO MAERA S25
Level probe
Applications
Level and level measurements
•In rainwater cisterns
•In gray water recycling
•Heating oil and diesel oil tanks
•In AUS32 (known in Europe as "AdBlue®", "DEF" in North America, or "ARLA 32" in Brazil)
Brief description
The JUMO MAERA S25 level probe is used for the continuous hydrostatic level measurement of
liquids. Filling heights between 2.50 mWS and 10 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 transferred as a standard signal. The signal is linearly proportional to the rising liquid column.
Any variations in air pressure are automatically compensated for using a protective hose and the
surrounding pressure is therefore taken into account.
Further information on our level probes from the JUMO MAERA series can be found in the brochure "Level probes – Hydrostatic level and level measurement" in the documentation.

Customer benefits
•Economic
The standardized, constructive design and constant optimization of the production process
result in an excellent price-performance ratio of the level probe.
•Process-reliable
The core of the level probe is a piezoresistive measuring cell, which features high overload
resistance and is particularly safe, reliable, and temperature resistant. Each level probe is
tested in a fully automated measuring and calibration facility to ensure consistently high
product quality. A reverse-polarity protection mechanism protects the measuring instrument
against damage, ensuring maximum safety during startup.

Electrical connection
For this construction, a stranded PVC cable is encased in an application-oriented protective hose made from either PE or PA.
To prevent moisture penetrating into the protective hose, in this case the pressure equalization hose, the delivery includes a hose end piece with
the fitting materials.

variant JUMO MAERA S25 (type 401015).
It is used to mount the level probes cost-effectively and in the best
possible way. Protection type IP 67 is achieved.
By using it locally with the tank mounting or wall mounting versions, a
rapid pressure compensation can be achieved and the length of the
special cable can be minimized. The costs are thereby reduced as an
electric standard cable can be used as the outgoing cable from the terminal head.
Furthermore, the direction (for example to the control cabinet) can be
individually specified.

Scope of delivery
ItemDescription
Hose end pieceWith this device, a standard cable is encased in a protective hose suitable for the application. The
hose end piece prevents the hose, which is used as a pressure compensation hose, from being
cut off or bent, for example when being routed through a wall. The hose end piece may be used
for example in routing through walls in masonry, clamp or cutting ring fittings in a tank, or cable
glands in a control cabinet.
The hose end piece is supplied with the device.
