HACH Inductive Conductivity Sensors

Conductivity

    Product Information

    Applications

    • Drinking water
    • Wastewater
    • Pure water/power
    • Industrial water


    Hach’s Inductive Conductivity Sensors measure 200 up to 2,000,000 microSiemens/cm. A built-in Pt 1000 RTD compensates the measured conductivity for changes in process temperature.

    The inductive sensor design eliminates polarisation and electrode coating problems that commonly affect conventional contacting electrode-type conductivity sensors.

    All 3700 sc sensors come complete with a Digital Gateway for use with a Hach sc Digital Controller.

    Inductive conductivity sensors induce a low current in a closed loop of solution, then measure the magnitude of this current to determine the solution’s conductivity. The conductivity analyser drives Torroid A, inducing an alternating current in the solution. This current signal flows in a closed loop through the sensor bore and surrounding solution. Torroid B senses the magnitude of the induced current which is proportional to the conductance of the solution. The analyser processes this signal and displays the corresponding reading.

    There are no complicated wiring or setup procedures with any Hach sc controller. Just plug in any combination of Hach digital sensors and it’s ready to use— it’s “plug and play.”
