Field of application
Memosens CLS82E is a high-end, hygienic sensor for applications with widely varying conductivity values. It enables reliable monitoring of core processes as well as final rinse with only one sensor. FDA compliance and a small, compact design ensure the perfect fit to your processes. With Memosens 2.0 digital technology, CLS82E allows for extended storage of process and sensor data facilitating lab calibration and predictive maintenance and providing the perfect basis for enhanced IIoT services.
Memosens CLS82E measures conductivity in applications that need to cover a wide measuring range as in:
Phase separation
Downstream processing
Fermentation
Chromatography
Ultrafiltration
Final rinse in pharma applications
With its international explosion protection approvals, such as ATEX, FM, CSA and NEPSI, the digital sensor is suitable for hazardous area use.
Benefits
Hygienic design and materials certified and approved by EHEDG, 3-A and FDA ensure compliance with GMP requirements. The sensor is sterilizable and autoclavable.
Absolute loop safety thanks to Memosens and unique detection of build-up on electrodes.
The broad measuring range enables monitoring of core processes and final rinse with one sensor, saving costs.
Its compact design makes the sensor suitable for small pipe diameters and narrow, space-limited installations.
Quality certificate stating the individual cell constant allows precise adjustment of the measurement.
Non-contact, inductive signal transmission ensures high process and data integrity.
IIoT ready: Memosens 2.0 offers extended storage of calibration and process data, enabling better trend identification and providing a future-proof basis for predictive maintenance and enhanced IIoT services.
