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 A complete measuring system consists of the following components at least:
- ORP sensor CPS62E
- Memosens data cable CYK10 or CYK20
- Transmitter, e.g. Liquiline CM44x, Liquiline CM42
- Assembly
- Retractable assembly, e.g. Cleanfit CPA875
- 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 A0031152 1 Example of a measuring system for pH measurement

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. This includes 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 The data listed above can be displayed with the Liquiline CM42, CM44x, and Memobase Plus CYZ71D. 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 evaluation programs, e.g. Memobase Plus CYZ71D,.
- The saved application data of the sensor can be used to determine the continued use of the sensor in a targeted manner. Integrity 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.

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.

Before screwing in the sensor, make sure the assembly thread, the O-rings and the sealing surface are clean and undamaged and that the thread runs smoothly. 2. Screw in the sensor and tighten by hand with a torque of 3 Nm (2.21 lbf ft) (specifications only apply if installing in Endress+Hauser assemblies). For detailed information on removing the moistening cap, see BA01988C Hygienic requirements Devices in hygienic applications place specific demands on the installation. These must be taken into account in order to guarantee hygienic operation without contamination of the process medium. Special Documentation for hygienic applications, SD02751C For 3-A-compliant and easy-clean installation, please observe the following:
- Use a certified process assembly
- Use a process assembly with a protective guard around the sensor
- The installation must be self-draining
- Dead areas should be avoided It is recommended to change the sensor after 20 CIP cycles.
