ENDRESS+HAUSER  CPS42D-7PB4AC

ORP electrodes with ceramic diaphragm and liquid KCl electrolyte

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

• 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
• Three lengths available: 120, 225 and 425 mm / 4.72, 8.86 and 16.73 inches

• 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

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.

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
