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 pipesFood & beverages:
- Phase separation of product/product mixtures in pipe systemsWastewater 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
