WSDEC1001 Conductivity Sensor

The WSDEC1001 is a digital online conductivity sensor that uses the four-electrode measuring principle for continuous monitoring of water conductivity. An AC voltage applied between the two outer electrodes induces an ionic current in the solution, proportional to the concentration of ions in the water; the current measured between the two inner electrodes gives the conductivity value. A built-in temperature sensor provides real-time temperature compensation, and the sensor converts the reading to a digital signal on board. Output is RS485 with the standard Modbus RTU protocol, which resists interference and carries the signal up to 500 m, and electrode parameters can be set and calibrated remotely.

How it works

• AC voltage is applied between the two outer electrodes
• This induces an ionic current proportional to the ion concentration
• The current between the two inner electrodes is measured to give conductivity

Applications

• Continuous online conductivity monitoring of water
• Immersion (sinking) installation
• Pipeline installation
