Conductive conductivity sensors

Sonde de Conductivité Conductive

Graphite conductive conductivity sensors : CAA2640 to CAA2643
Graphite conductive conductivity sensors : CAA2648 – 49 and CAA2680 – 81
4-20 mA output

CAA2640 – 43 and CAA2648 – 49 sensors are used to measure conductivity with “graphite” electrode. These sensors are not suitable for low-mineralized water.
CAA2648 – 49 sensors provide a 4-20 mA analog signal for connection over long distances. A temperature sensor is integrated to enable the transmission of a compensated signal based on water temperature.
