CLS15E

Two electrodes immersed in the process medium measure the electrical conductivity of the liquid. An AC voltage applied across the electrodes generates a current through the medium. According to Ohm’s law, the resistance or conductance G (the reciprocal of resistance) is calculated. The cell constant k, determined by the sensor geometry, is used to calculate the conductivity of the process medium from the measured conductance.

The Memosens CLS15E conductivity sensor is particularly suitable for low-conductivity applications such as boiler feedwater and semiconductor wafer cleaning. It provides reliable and highly accurate conductivity measurement, even in hazardous areas. The CLS15E uses Memosens 2.0 digital technology with extended data storage for calibration, configuration, and process parameters. This provides an ideal foundation for predictive maintenance and IIoT applications. The Memosens CLS15E is designed for conductivity measurement in pure and ultrapure water applications, including: • Process monitoring • Boiler feedwater • Ion exchange columns • Reverse osmosis systems • Recirculating cooling water • Distillation columns • Semiconductor wafer cleaning • Power plant applications, including degassed conductivity measurement and pH measurement based on differential conductivity
