Function and system design Measuring principle pH measurement The pH value is used as a unit of measurement for the acidity or alkalinity of a medium. The membrane glass of the electrode delivers an electrochemical potential that depends on the pH value of the medium. This potential is generated by the selective accumulation of H+ ions on the outer layer of the membrane. As a result, an electrochemical boundary layer with an electrical potential difference forms at this point. An integrated Ag/AgCl reference system serves as the required reference electrode. The measured voltage is converted to the corresponding pH value using the Nernst equation. Measuring system A complete measuring system comprises at least:
- pH sensor CPS11D or CPS11
- Transmitter, e.g. Liquiline CM42, CM44x, Mycom S CPM153, Liquisys M CPM2x3
- Memosens data cable CYK10 for Memosens sensors or CPK9 for analog sensors
- 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 Other options are available depending on the application: automatic cleaning and calibration system, e.g. Liquiline Control CDC90 A0025757 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. These include the following:
- Manufacturer data
- Serial number
- Order code
- Date of manufacture
- Calibration data
- Calibration date
- Slope at 25 °C (77 °F)
- Zero point at 25 °C (77 °F)
- Offset of integrated temperature sensor
- Number of calibrations
- Calibration history
- Serial number of the transmitter used to perform the last calibration or adjustment
- Application data
- Temperature application range
- pH application range
- Date of initial commissioning
- Maximum temperature value
- Hours of operation under extreme conditions
- Number of sterilizations
- Resistance of glass membrane
- CIP counter The data listed above can be displayed with 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 with external data carriers and evaluation programs, e.g. Memobase Plus CYZ71D.
- Thus, the current application of the sensors can be made to depend on their previous history. 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. Security 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 high- impedance" 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.
