Application

Media with very low conductivity or a high proportion of organic solvents or alcohol:

  • Food industry
  • Biotechnology
  • Laboratory measurements
  • Power plant

With ATEX, FM and CSA approval for application in hazardous areas

Your benefits
  • Liquid KCl electrolyte enabling use at very low conductivities
  • Ceramic diaphragm with defined KCl flow
  • Application under pressures of up to 10 bar / 145 psi with counter pressure
  • Resistant to poisoning thanks to separate reference lead
  • Suitable for CIP / SIP cleaning

Further benefits offered by Memosens technology
  • Maximum process safety through contactless inductive signal transmission
  • Data safety through digital data transmission
  • Easy handling due to storage of sensor-specific data
  • Predictive maintenance possible thanks to registration of sensor load data
Measuring principle Redox measurement

The redox potential is a unit of measurement for the state of equilibria between oxidising and reducing components of a medium. Redox potential is measured similarly to the pH value. A platinum or gold electrode is used instead of pH-sensitive membrane glass. Analog to the pH measurement, an integrated Ag/AgCl reference system is used as a reference electrode.

Measuring system

A complete measuring system comprises:

  • CPS42 or CPS42D ORP electrode
  • Transmitter, e.g. Liquisys M CPM223/253 (with Memosens technology for CPS42D)
  • Special measuring cable, e.g. CPK9 or CYK Memosens data cable for CPS42D
  • Immersion, flow or retractable assembly, e.g. Unifit H CPA441

Measuring principle

Sensor ORP / Redox

Application

- Special applications with high requirements with regard to accuracy, speed - rapidly changing composition of media, highly clogging media, low conductivities.

Characteristic
