Other advantages of Memosens technology
    Maximum process safety thanks to non-contact, inductive signal transmission Data security thanks to digital data transmission Very easy to use as sensor data saved in the sensor Recording of sensor load data in the sensor enables predictive maintenance with the Memobase Plus CYZ71D
Measuring principle pH measurement

The pH value is used as a unit of measurement for the acidity or alkalinity of a liquid medium. The membrane glass of the electrode supplies an electrochemical potential which is dependent upon the pH value of the medium. This potential is generated by the selective penetration of H + ions through the outer layer of the membrane. An electrochemical boundary layer with an electric potential forms at this point. An integrated Ag/AgCl reference system serves as the required reference electrode. The transmitter converts the measured voltage into the corresponding pH value using the Nernst equation.

Measuring system

A complete measuring system comprises:

  • pH electrode CPS71D or CPS71
  • Transmitter, e.g. Liquiline CM42, CM44x/R, Mycom S CPM153, Liquisys M CPM2x3
  • Memosens data cable CYK10 for Memosens sensors or CPK9 for analog sensors
  • Immersion, flow or retractable assembly, e.g. Cleanfit CPA871/875
