电导率传感器
For the same analog range, use CLS21; for low-range analog measurement of pure water, use CLS19; for digital, use CLS15D.
Condumax CLS21D is a robust conductivity sensor suitable for all process and environmental industries. It provides accurate and reliable measured values to optimize process and product quality monitoring. Even better, the sensor has extremely high chemical, thermal and mechanical stability and is robust. Based on Memosens digital technology, CLS21D achieves maximum process and data integrity through simple operation, is corrosion-resistant, moisture-proof and enables predictive maintenance.
Benefits
Reliable and accurate measurement in medium/high conductivity applications
Robust with low maintenance requirements
High chemical, thermal and mechanical stability
Quality certificate with independent cell constant specification
Sensor-specific parameters are recorded for traceability and predictive maintenance
Maximum process safety through non-contact inductive signal transmission
Application
Condumax CLS21D is used for conductivity measurement in the process and environmental industries, such as:
Drinking water treatment
Desalination plants
Industrial water treatment
River/lake water monitoring
Phase separation in medium conductivity applications (e.g. milk/water)
With various international explosion protection approvals, such as ATEX, FM, CSA and NEPSI, this digital sensor is suitable for hazardous areas
