Field of application
Indumax CLS50D is a digital 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. Thanks to Memosens, CLS50D combines maximum process and data integrity with simple operation. It resists corrosion and moisture and facilitates predictive maintenance.
Indumax CLS50D 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 systemsLife Sciences:
- 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
Reliable values thanks to active connection monitoring
Easy wiring over long distances without impact on the measurement accuracy
-
Logging of sensor-specific data for easy traceability
-
Approved for hazardous area use
