Field of application
Ceragel CPS71D is the digital specialist for demanding processes and hygienic applications. Its contamination-resistant gel guarantees stable measurement even in flowing media or low conductivity. The sensor measures reliably at high temperatures and is non-toxic assuring highest safety. Ceragel CPS71D is not the latest Memosens generation. To get information on the new Memosens sensors with extended functionality, click CPS71E for chemical applications and CPS61E for hygienic applications.
Process technology and monitoring of processes with:
- Quickly changing pH values
- High proportion of electrode poisons such as H2SChemical industry
Hygienic and sterile applications:
- Fermenters
- Biotechnology
- Life sciences
With ATEX, FM, and CSA approval for application in hazardous areas
Benefits
Sensor resists strong acids and bases and high organic loads
Suitable for CIP/SIP and autoclaving maintaining high accuracy
Free from animal-based materials and from acrylamide
Maximum process safety through non-contact inductive signal transmission
Enables predictive maintenance due to storage of sensor and process-specific data
Reduced operating costs thanks to minimized process downtime and extended sensor lifetime
Videos
-
The pH-value of a liquid can be calculated using the potentiometric measurement principle. This video shows what it is about and how this measuring principle works.
-
Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.
