Field of application

Indumax CLS50 is an inductive conductivity sensor for standard, hazardous and high-temperature applications. Benefit from high chemical resistance and long durability thanks to robust materials (PFA, PEEK). Moreover, it is insensitive to soiling and performs reliable and repeatable even in harsh and aggressive media. The wide temperature range of -20 to +180 °C leaves nothing to be desired.

Indumax CLS50 measures toroidal conductivity in:

  • Chemicals:
    - Concentration measurement of acids and bases
    - Quality monitoring of chemical products in tanks and pipes

  • Food & beverages:
    - Phase separation of product/product mixtures in pipe systems

  • Wastewater industry:
    - Inlet monitoring

With its international explosion protection approvals, such as ATEX, FM, CSA, NEPSI, it is suitable for hazardous areas.

Benefits

  • High durability and chemical resistance even under harsh conditions

  • Dirt-repellent materials and large sensor opening avoid soiling

  • Wide temperature range and highly resistant materials make the sensor suitable for virtual any application

  • Robust design for outstanding long operating life

  • Approved for hazardous area use

Videos

  • The conductivity of a liquid can be measured using the conductive or toroidal measuring principles. This video shows what it is about and how these measuring principles work.
