Brief overview
The conductivity sensor has 4 electrodes made of robust
special graphite and features a large measuring range. As
a result, it is predestined for determining the conductivity
of high salt concentrations. It is therefore not only used in
drinking and process water plants but also in such applica-
tions as salt and sea water. The proven design allows the
sensor to be easily installed in commercially available pro-
cess fittings with a Pg 13.5 thread.
Advantages of JUMO digiLine electronic
components
The use of JUMO digiLine electronic components en-
sures interference-free digital data transmission for op-
timum process monitoring. The modular system can be
used for individual measuring points as well as for sensor
networks. Plug and Play functionality when connected to
transmitters from the JUMO AQUIS touch series facilitates
the exchange of sensors. The JUMO DSM (Digital Sensor
Management) software tool enables simple, reliable sen-
sor calibration as well as comprehensive measuring point
management to be conveniently carried out on a PC. A ver-
sion with analog output (4to20mA) allows integration into
existing plants.
