CCS58E

Summary

Product Identification

• Product Name: Memosens CCS58E
• Description: Digital sensor with Memosens technology for determining ozone.
• Applications: Wastewater (discharge guarantee), Drinking water (disinfection), Process water (hygienic packaging and bottling).

Measuring Principle

The CCS58E utilizes an amperometric measuring principle to determine ozone (O₃). Ozone diffuses through a membrane and is reduced to hydroxide ions (OH⁻) at the working electrode. A current flows, proportional to the ozone concentration, which is then used by the transmitter to calculate the concentration in mg/l (ppm). This process is largely independent of pH over a wide range.

Key Features and Benefits

• Robust Membrane Technology: High surfactant resistance, suitable for cleaning processes.
• High Specificity for Ozone: Ensures reliable measured values for disinfection.
• Heartbeat Technology: Offers advanced capabilities like an electrolyte counter for predictive maintenance.
• Fast Commissioning: Factory calibration and plug-and-play installation.
• Memosens Technology:
  • Non-contact, digital signal transmission.
  • Galvanic isolation, dust- and waterproof (IP 68).
  • Sensor can be calibrated in a lab.
  • Intrinsically safe electronics for use in hazardous areas.
  • Stores sensor data (total hours, extreme condition hours, temperature hours, calibration history) for predictive maintenance and documentation.
  • Easy calibration and quick sensor replacement, increasing measuring point availability.
• Cross-Sensitivity: No cross-sensitivities to free chlorine, free bromine, total chlorine, total bromine, hydrogen peroxide, peracetic acid. Minimum cross-sensitivity to chlorine dioxide. Surfactants do not affect performance.
