OVERVIEW

The JUMO MAERA F27 level probe is used for the continuous hydrostatic level measurement of
liquids. Filling heights between 0.5 mWS 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 transferred as a standard signal. The signal is linearly proportional to the rising liquid column.

FEATURES

• Process-reliable
  The combination of a mechanically highly stress-resistant membrane with a stainless steel
  or PTFE case offers excellent chemical resistance against aggressive mediums. A reversepolarity protection mechanism protects the measuring instrument against damage, ensuring
  maximum safety during startup. 

• Versatile and uncomplicated
  The simultaneous measurement of level and temperature may be optionally achieved with
  a Pt100 temperature sensor. As the measuring range already starts from 50 mbar
  (0.5 mWS), even low level filling heights can be reliably monitored. A further temperature
  range of 80 K enables the use of many applications.
