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. 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. Analog to the pH measurement, an integrated Ag/AgCl reference system is used as a reference electrode. Measuring system A complete measuring system comprises:
- Sensor CPF81D, CPF81, CPF82D or CPF82
- Transmitter, e.g. Liquiline CM44x/R or Liquiline M CM42
- Measuring cable, e.g. CYK10 or sensor fixed cable A0024721 1 Example of a measuring system

Communication and data transmission 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.
Orbipac CPF81D/CPF82D and CPF81/CPF82 Endress+Hauser 3 Digital sensors can store measuring system data in the sensor. These include the following:
- Manufacturing data
- Serial number
- Order code
- Date of manufacture
- Calibration data
- Calibration date
- Calibrated slope at 25 °C (77 °F) (CPF81D)
- Calibrated zero point at 25 °C (77 °F) (CPF81D)
- Calibrated offset (CPF82D, ORP mV measuring mode)
- Slope as % (CPF82D, ORP % measuring mode)
- Temperature offset
- Number of calibrations
- Serial number of the transmitter used for the last calibration
- Calibration database (stores the last 8 calibrations in the Memosens head)
- Application data
- Temperature application range
- pH application range (CPF81D)
- ORP application range (CPF82D)
- Date of first commissioning
- Maximum temperature value
- Operating hours at temperatures above 80 °C (176 °F) and 100 °C (212 °F)
- Operating hours at very low and very high pH values (Nernst voltage below -300 mV, above +300 mV) Reliability Dependability 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.
- Thus, the current application of the sensors can be made to depend on their previous history. 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:
- Automatic error message if sensor fails or connection between sensor and transmitter is interrupted
- Immediate error detection increases measuring point availability 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:
- 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.
