Conductivity sensors for optimum process integration: DULCOTEST® sensors meet a wide range of measuring requirements and allow the best solution to any given measuring task to be achieved.

Product description

Online measurement of electrolytic conductivity – with the reliable DULCOTEST® sensors.

After pH, electrolytic conductivity is the second most important measured variable in chemical process analysis. It characterises the ability of an aqueous solution to conduct electrical current. This allows all processes involving salts, acids and bases to be accurately monitored and controlled.

The field of application covers everything from fairly simple water treatment tasks through to complex industrial process waters with stringent requirements in terms of temperature, pressure, contamination tolerance and chemical resistance (e.g. to concentrated sulphuric acid or hydrofluoric acid).

    2-Electrode Conductivity Sensors

    Conductive conductivity sensors measure the electrolytic conductivity indirectly via the charge transfer between two electrodes immersed in the medium to be measured. The sensor types with cell constants k = 0.01 and k = 0.1 cm-1 are especially suitable for the measurement of the lowest electrolytic conductivities of < 1 µS/cm in pure and ultra-pure kinds of water.

    The sensor types with cell constants k=1 cm-1 are used in numerous kinds of water without film-forming ingredients up to 20 mS/cm. The cost-effective sensor range LF(T) is used in clear, chemically uncontaminated water.

    The sensor ranges LM(P), CK and CKPt can also be used in chemically contaminated kinds of water and a high temperatures.

    Inductive Conductivity Sensors

    Inductive conductivity sensors consist of a transducer, encapsulated in an inert material. The electrolytic conductivity is measured inductively without direct contact with the medium.

    The sensors are used to measure electrolytic conductivity over a wide measuring range, even in heavily contaminated and/or aggressive media and, as such, offer particularly low maintenance operation. The sensors are particularly suitable for measuring high conductivities, as no electrode polarisation occurs. The inductive conductivity sensors are operated using the Compact controller DCCa xx L6 ... The controller includes the testing and calibration kit (Order no. 1026958).

    Overview

    Online measurement of electrolytic conductivity – with the reliable DULCOTEST® sensors.

    After pH, electrolytic conductivity is the second most important measured variable in chemical process analysis. It characterises the ability of an aqueous solution to conduct electrical current. This allows all processes involving salts, acids and bases to be accurately monitored and controlled.

    The field of application covers everything from fairly simple water treatment tasks through to complex industrial process waters with stringent requirements in terms of temperature, pressure, contamination tolerance and chemical resistance (e.g. to concentrated sulphuric acid or hydrofluoric acid).

    Your benefits

    • 27 different sensor types tailored to different requirements and offering optimum performance for money: measuring range, temperature, chemical resistance, contamination tolerance and process integration
    • From simple conductometric sensors to high-end sensors based on the inductive measurement principle
    • Precise and reliable measurement enables efficient processes and maximum process reliability
    • Long service lives and short maintenance intervals reduce downtime and increase the availability of the measured values
    • Complete pre-assembled kits containing fitting and sensor for easy, fast and error-free installation
    • Prompt delivery for quick replacement
