Compact pH Measurement for Harsh Conditions
The CPF81E is designed for applications where a conventional pH electrode may face challenging process conditions. Its robust construction allows reliable measurement in abrasive media and at high flow rates, making it particularly suitable for industrial water treatment and mining-related processes.
The integrated assembly also makes the sensor more compact, helping reduce the space required at the measuring point.
Digital Memosens 2.0 Technology
The CPF81E uses Memosens 2.0 digital sensor technology. Instead of transferring the raw sensor signal directly through a conventional analog connection, measurement data is converted into a digital signal and transferred to the transmitter through the Memosens connection.
The sensor can also store calibration and process information, providing useful data for sensor management and maintenance.
Built for Abrasive Media
One of the key characteristics of the CPF81E is its suitability for abrasive media and high flow rates. This makes it particularly relevant for processes such as flotation, leaching and industrial wastewater treatment where the measuring environment can be considerably more demanding than standard water applications.
Compact Integrated Assembly
Unlike a conventional separate electrode-and-holder arrangement, the CPF81E incorporates its assembly into the sensor design. This reduces installation space and provides a straightforward solution for compact measuring points.
Calibration and Sensor Data Management
The Memosens design allows the sensor to be calibrated outside the process, which can make maintenance more convenient. Calibration and process data can also be stored within the sensor, supporting easier sensor replacement and maintenance management.
