Function and system design Measuring principle AC I U A0024260  1 Conductive measurement of conductivity AC Alternating voltage source I Current intensity measurement U Voltage measurement Conductivity of liquids is determined with a measuring arrangement where two electrodes are located in the medium. An alternating voltage that causes a current to flow through the medium is applied at these electrodes. The electrical resistance, or its reciprocal value - conductance G - is calculated based on Ohm's law. The specific conductance κ is determined from the conductance value using the cell constant k, which depends on the sensor geometry. Measuring system A complete measuring system comprises the following components at least:

  • The conductively measuring conductivity sensor CLS15D or CLS15
  • A transmitter, e.g. Liquiline M CM42
  • A measuring cable, e.g. Memosens data cable CYK10 or CYK71 for analog sensors A0022850  2 Example of a measuring system (with Memosens sensor)

Communication and data processing (only CLS15D) 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 are able to store the following system data in the sensor

  • Manufacturing 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 for the last calibration
  • Application data – Temperature application range – Conductivity application range – Date of first commissioning – Maximum temperature value – Hours of operation at high temperatures Dependability (only CLS15D) Reliability Memosens technology digitizes the measured values in the sensor and transmits the data to the transmitter using 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 Maintainability Easy handling Sensors with Memosens technology have integrated electronics that allow for saving calibration data and further information such as total hours of operation and 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 .
  • Maintenance intervals can be defined based on all stored sensor load and calibration data and predictive maintenance is possible.
  • The sensor history can be documented on external data carriers and evaluation programs at any time. 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 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.
