cCare | Knick's Fully Automated pH Sensor Maintenance System

cCare is a sensor maintenance system that cleans and calibrates pH sensors fully automatically, thus extending their service life.

In the process industry, the pH value is the most important parameter for controlling chemical reactions and the consumption of raw materials. There is a solution from Knick for extending the service life of pH sensors, especially with aggressive viscoses and abrasive media: cCare ensures accurate measurements through fully automatic cleaning and calibration of pH sensors and reduces maintenance and material costs at the same time. As an autonomous measuring system, cCare supplies reliable values directly to the process control systems. In this way, cCare not only contributes to process optimization, product quality, and the safety of people and the environment, but also to end-to-end digitalization in the process industry.

Benefits of cCare in a nutshell:

Reducing maintenance costs
In the worst case, inaccurate pH readings can cause rejects in high-throughput productions or pose a risk when dealing with hazardous substances. The regular maintenance of pH sensors is therefore essential, but at the same time labor- and material- intensive, especially in large plants or in harsh ambient conditions.

Safety and Ex approval
Many measuring points are located in explosive or toxic areas where human presence is restricted or even prohibited. As the only sensor maintenance system on the market, cCare with all components is approved for use in Ex Zone 1. Additionally, the required stay in the hazardous areas is considerably reduced by the automation of maintenance.

A modular system for all requirements
cCare is a flexible system that can be adapted to any application. The system consists of a Unical 9000 or Uniclean 900 electro-pneumatic controller, a retractable fitting from the Ceramat or SensoGate series, and a Protos transmitter. The system is completed by media containers with integrated pneumatic metering pumps. The components are modular in design. The fittings are adaptable to any application through many materials, process customization, and immersion lengths.

Efficiency through accurate measurements and digitalization
cCare fully automates every pH measuring point and thus contributes to end-to-end digitalization from the sensor to the process control system. The system communicates with the process control system via fieldbus. Thanks to the maximum available and reliable values, the control system can react perfectly.
