Function and system design Measuring principle 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. Similar to pH measurement, an integrated Ag/AgCl reference system is used as a reference electrode. Measuring system The complete measuring system comprises at least:

ORP sensor CPS12E
Memosens data cable CYK10 or CYK20
Transmitter, e. g. Liquiline CM44, Liquiline CM42
Assembly
Immersion assembly, e. g. Dipfit CPA111
Flow assembly, e. g. Flowfit CPA250
Retractable assembly, e. g. Cleanfit CPA871
Permanent installation assembly, e. g. Unifit CPA842 Additional options are available depending on the application: Automatic cleaning and calibration system, e. g. Liquiline Control CDC90 A0032144  1 Example of a measuring system for ORP measurement

The ORP sensor is available with a gold or platinum electrode:

Gold electrode For oxidizing media, e. g. cyanide oxidization, nitrite oxidization, ozone measurement, hydrogen superoxide measurement
Platinum electrode For reducing media, e. g. chromate reduction or for chlorine dosing in swimming pools Communication and data processing 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 of integrated temperature sensor
Offset of ORP measurement
Number of calibrations
Calibration history
Serial number of the transmitter used to perform the last calibration or adjustment
Operating data
Temperature application range
ORP application range
Date of initial commissioning
Maximum temperature value
Hours of operation under extreme conditions
Number of sterilizations
CIP counter Dependability Reliability Easy handling Sensors with Memosens technology have integrated electronics that store calibration data and other information (e. g. total hours of operation or 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.
Thanks to the availability of the sensor data, maintenance intervals can be accurately defined and predictive maintenance is possible.
The sensor history can be documented on external data carriers and in evaluation programs.
The saved application data of the sensor can be used to determine the continued use of the sensor in a targeted manner. Interference immunity Data security thanks to digital data transmission Memosens technology digitizes the measured values in the sensor and transmits the data to the transmitter via a non-contact connection that is free from potential interference. The result:
If the sensor fails or there is an interruption in the connection between the sensor and transmitter, this is reliably detected and reported.
The availability of the measuring point is reliably detected and reported. Safety 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:
No corrosion at the connection
Measured values cannot be distorted by moisture
The transmitter is galvanically decoupled from the medium. Issues concerning "symmetrical high- impedance" or "asymmetry" or the type of impedance converter are a thing of the past.
Electromagnetic compatibility (EMC) is guaranteed by screening measures for the digital transmission of measured values.
Intrinsically safe electronics mean operation in hazardous areas is not a problem. Complete flexibility thanks to individual Ex approvals for all components, such as sensors, cables and transmitters.
