Function and system design Measuring principle The measuring cell has four electrodes. An alternating current is applied via the outer electrode pair. At the same time, the voltage applied is measured at the two inner electrodes. The electrolytic conductivity between the electrodes can be reliably established based on the measured voltage and the current flow caused by the liquid's resistance. The advantage of this technology compared to traditional two-electrode sensors is that electrochemical effects at the live electrodes are suppressed by the two additional voltage measuring electrodes.

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
  • Cell constant
  • Delta cell constant
  • Number of calibrations
  • Serial number of the transmitter used to perform the last calibration or adjustment
  • Application data
  • Temperature application range
  • Conductivity application range
  • Date of initial commissioning
  • Maximum temperature value
  • Hours of operation at high temperatures Dependability Reliability Memosens technology digitizes the measured values in the sensor and transmits the data to the transmitter via a . 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. Maintainability 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.
  • Thus, the current application of the sensors can be made to depend on their previous history. Integrity 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 remains free from corrosion
  • Measured value distortion from moisture is not possible.
  • The plug-in system can even be connected under water.
  • The transmitter is galvanically decoupled from the medium.
  • EMC safety is guaranteed by screening measures for the digital transmission of measured values.

The ionic current in the liquid is affected by the walls in confined installation conditions. This effect is compensated by what is referred to as the installation factor. The installation factor can be entered in the transmitter for the measurement or the cell constant is corrected by multiplying by the installation factor. The value of the installation factor depends on the diameter and the conductivity of the pipe nozzle as well as the sensor's distance to the wall. The installation factor can be disregarded (f = 1.00) if the distance to the wall is sufficient (a > 15 mm). If the distance to the wall is smaller, the installation factor increases for electrically insulating pipes (f > 1) and decreases for electrically conductive pipes (f < 1). The installation factor can be determined using calibration solutions. b a A0024626  5 Schematic drawing of the sensor in confined installation conditions a Wall distance b Gap width
