Digital Four-Electrode Conductivity Sensor for Flexible Sampling
The Endress+Hauser Memosens CLL47E is a digital conductivity sensor designed specifically for random sampling, laboratory measurements and verification of online measuring loops.
Unlike permanently installed process sensors, the CLL47E is optimized for flexible measurement tasks where operators need to quickly check conductivity values at different locations or analyze collected samples in the laboratory.
With its four-electrode measuring principle, the sensor provides a wide measuring range and stable measurement performance across different liquid applications.
Typical applications include:
Drinking water analysis
Cooling water monitoring
Wastewater testing
Process media analysis
Laboratory conductivity measurements
Verification of installed conductivity measuring points
Wide Measuring Range for Different Liquid Applications
A major advantage of the CLL47E is its wide conductivity measuring range.
The sensor can measure conductivity from:
5 μS/cm to 200 mS/cm
This allows one sensor to cover a broad range of samples, from low-conductivity water applications to higher-conductivity process liquids.
The wide range makes the CLL47E suitable for various measurement tasks without requiring multiple sensor types for different conductivity levels.
Memosens 2.0 Technology for Reliable Digital Measurement
The CLL47E uses Memosens 2.0 digital sensor technology, providing reliable data transfer and simplified sensor management.
Memosens technology stores important sensor information directly inside the sensor, including:
Calibration data
Operating history
Sensor identification information
Benefits include:
Easy sensor replacement
Reduced calibration effort
Improved measurement reliability
Simplified maintenance management
The digital connection also helps prevent measurement errors caused by moisture or signal interference commonly associated with traditional analog sensor connections.
Four-Electrode Design for Stable Conductivity Measurement
The CLL47E uses a four-electrode conductivity measuring principle with platinum electrodes.
Compared with conventional two-electrode conductivity sensors, four-electrode technology provides improved flexibility when measuring samples with different conductivity levels.
Advantages include:
Wider measuring range
Reliable measurement of changing conductivity conditions
Better adaptability for different sample types
Stable measurement performance during field testing
This makes the sensor suitable for both laboratory analysis and on-site measurement tasks.
Designed for Random Sampling and Laboratory Use
The CLL47E is developed for applications where measurements are performed at different sampling points rather than continuously installed in the process.
Typical usage scenarios include:
Verification of Online Measuring Loops
Operators can use the CLL47E to compare handheld or laboratory measurements with installed conductivity transmitters, helping verify system accuracy.
Laboratory Sample Analysis
The sensor can be used for conductivity measurement of collected liquid samples, providing reliable analytical data for quality control.
