Graphite Conductivity sensor

sonde de conductivite graphite syclope

Sensors CAA2690 and CAA2790 : Graphite conductivity 4-20 mA

The intelligent conductivity sensor CAA2690 is a full programmable electrical conductivity sensor made with graphite electrodes. The sensor delivers a passive isolated 4…20mA signal with a long wiring capability. It includes an integrated temperature sensor which allows to compensate the signal with the temperature water.

The electrodes are integrated into a Plexiglas head which allows a high capacities against corrosion and chemical products.

This sensor is particularly used for measuring water with a high mineralogy, into cooling towers, for salinity measurement or for water with similar conductivity.
