Measuring principle
Measuring system
ORP measurement
The ORP potential is a unit of measurement for the state of equilibria between oxidizing and
reducing components of a medium. The ORP is measured using a platinum or gold electrode instead
of the pH-sensitive glass membrane. Analog to the pH measurement, an integrated Ag/AgCl
reference system is used as a reference electrode.
A complete measuring system consists of the following components at least:
• ORP electrode CPS92D or CPS92
• 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

Communication and data processing CPS92D
Communication with the transmitter
Always connect digital sensors with Memosens technology to a transmitter with Memosens
technology. Data transmission to a transmitter for analog sensors is not possible.
Digital sensors can store measuring system data in the sensor. These include the following:
• Manufacturer data
– Serial number
– Order code
– Date of manufacture
• Calibration data
– Calibration date
– Offset (operating mode "mV")
– % slope (operating mode "%")
– Number of calibrations
– Serial number of the transmitter used to perform the last calibration
• Operating data
– Temperature application range
– ORP application range
– Date of initial commissioning
– Hours of operation under extreme conditions
You can display the abovementioned data using the Liquiline CM44x, CM42 and Memobase Plus
CYZ71D.

Safety
Easy handling
Sensors with Memosens technology have an integrated electronics unit that stores calibration data
and other information (e.g. total operating hours and operating hours under extreme measuring
conditions). Once the sensor has been connected, the sensor data are transferred automatically to
the transmitter and used to calculate the current measured value. As the calibration data are stored
in the sensor, the sensor can be calibrated and adjusted independently of the measuring point. The
result:
• Easy calibration in the measuring lab under optimum external conditions increases the quality of
the calibration.
• Pre-calibrated sensors can be replaced quickly and easily, resulting in a dramatic increase in the
availability of the measuring point .
• 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 using external storage media and evaluation programs, e.g.
Memobase Plus CYZ71D. Thus, the current application of the sensors can be made to depend on
their previous history.
Memosens technology digitizes the measured values in the sensor and transmits the data to the
transmitter using a non-contact connection that is free from potential interference. The result:
• Automatic error message if sensor fails or connection between sensor and transmitter is
interrupted
• Immediate error detection increases measuring point availability
Maximum process safety
With inductive transmission of the measured value using a non-contact connection, Memosens
guarantees maximum process safety and offers the following benefits:
• All problems caused by moisture are eliminated:
– Plug-in connection free from corrosion
– Measured values cannot be distorted by moisture.
– Can even be connected under water
• The transmitter is galvanically decoupled from the medium. Issues concerning "symmetrical highimpedance" or "asymmetry" or an impedance converter are a thing of the past.
• EMC safety is guaranteed by screening measures for the digital transmission of measured values.
• Intrinsically safe electronics mean operation in hazardous areas is not a problem.

Please note the process operating conditions.
Installation
Do not install the electrodes upside down. The angle of inclination must be at least 15° from the
horizontal. A smaller inclination angle is not permitted as it could cause an air bubble to form and
prevent contact between the reference and the lead.
NOTICE
Before screwing in the electrode, make sure the assembly threaded connection is clean and
runs smoothly.
Screw in the electrode finger-tight (3 Nm)! (Data apply only if installing with Endress+Hauser
‣
assemblies.)
Make sure to follow the installation instructions in the Operating Instructions of the assembly

used.
