Function and system design 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. General properties • Application at low conductivity Thanks to its liquid KCl electrolyte filling, the CPS42 can be applied at very low conductivities (≥ 5µ S / c m ) .

  • Sterilisable The electrode can be used in applications with steam sterilisation (max. 130 °C / 266 °F).
  • Durability The electrode can be applied under pressures of up to 10 bar /145 psi with counter pressure. Important properties CPS42D Maximum process safety The inductive and non-contacting measured value transmission of Memosens guarantees maximum process safety and offers the following benefits:
  • All problems caused by moisture are eliminated. – The plug-in connection is free from corrosion. – Measured value distortion from moisture is not possible. – The plug-in system can even be connected under water.
  • The transmitter is galvanically decoupled from the medium. The result: No more need to ask about "symmetrically high-impedance" or "unsymmetrical" or an impedance converter.
  • EMC safety is guaranteed by screening measures for the digital measured value transmission. Data safety through digital data transfer The Memosens technology digitalizes the measured value in the sensor and transfers it to the transmitter via a contactless connection. The result:
  • An automatic error message is generated if the sensor fails or the connection between sensor and transmitter is interrupted.
  • The availability of the measuring point is dram atically increased by immediate error detection.
  • The digital signals are suitable for application in hazardous areas; the integrated electronics are intrinsically safe. Easy handling Sensors with Memosens technology have integrated electronics that allow for saving calibration data and further information such as total hours of operation and operating hours at very high temperatures. When the sensor is mounted, the calibration data are automatically transferred to the transmitter and used to calculate the current redox potential. Storing the calibration data in the sensor allows for calibration and adjustment away from the measuring point. The result:
  • The sensors can be calibrated unter optimum external conditions in the measuring lab. Wind and weather do neither affect the calibration quality nor the operator.
  • The measuring point availability is dramatically increased by the quick and easy replacement of precalibrated sensors.
  • The transmitter does not need to be installed close to the measuring point but can be placed in the control room.
  • Maintenance intervals can be defined based on all stored sensor load and calibration data and predictive maintenance is possible.
  • The sensor history can be documented on external data carriers and evaluation programs at any time. Thus, the current application of the sensors can be made to depend on their previous history. Communication with the transmitter Always connect the digital sensor to a digital transmitter with Memosens technology. Data transmission to an analog transmitter is not possible.

Ceraliquid CPS42 / CPS42D / CPS43 Endress+Hauser 3 Data storage of the CPS42D Digital sensors are able to store the following system data in the sensor.

  • Manufacturing data – Serial number –O r d e r c o d e – Date of manufacture
  • Calibration data – Calibration date – Calibrated offset (operating mode "mV") – % slope (operating mode "%") – Number of calibrations – Serial number of the transmitter used for the last calibration
  • Application data – Temperature application range – Redox application range – Date of first commissioning – Operating hours These system data can be displayed with the Mycom S or the Liquiline M CM42 transmitter. Measuring system A complete measuring system comprises:
  • CPS42 or CPS42D ORP electrode

Installation instructions Do not install the electrode upside down. The inclination angle must be at least 15° from the horizontal. A smaller inclination angle is not permitted as such an inclination results in air cushion forming. This might impair the contact of reference and metal lead. " Caution!

  • Make sure that the assembly’s threaded connection for the electrode is clean and well running before installing the electrode.
  • Hand tighten the electrode (3 Nm)! (Given value only applies to installation in Endress+Hauser assemblies.)
  • Make sure to follow the installation instructions in the operating instructions of the used assembly. a0003686 Electrode installation; inclination angle min. 15° from the horizontal A Permitted inclination angle B Non-permitted inclination angle Environment Ambient temperature " Caution!
