  • Page 4: Measuring Principle

    Application The device is an electronic hydrostatic filling level transmitter for continuous measuring of filling levels in liquids within pressure-less container. The use of a capacitive measuring sensor with ceramic membrane and the corresponding excellent characteristics, allows the use in nearly all fields of industry. Optionally the device can be equipped with a process diaphragm seal.

  • Page 5: Signal Processing

    Signal processing The pressure signal, that is transmitted by the membrane to the sensor is converted into an electrical signal and processed by the integrated evaluation electronic according to the respective preferences. The measuring value is diagrammed at the display, whereby it can be selected between different display styles (digital value / manometer / chart / bar graph).

  • Page 6: Installation Place

    Installation The correct function of the device within the specific technical data can only be guaranteed, if the permitted process and environmental temperatures (see chapter „Technical data“) will not be exceeded. Installation place The installation of the device at locations where high pressure blows can occur should be avoided. At a filling level measurement in liquids, the device should be installed below the lowest measuring point.
  • Page 7 Process diaphragm seal A process diaphragm seal together with the measuring transmitter forms a closed, calibrated system, that is filled by openings in the process diaphragm seal and in the measuring system of the measuring transmitter. These openings are sealed and may not be opened. The standard reference temperature for pressure diaphragm seal systems is +20°C.

  • Page 8: Electrical Connection

    Electrical connection The electrical connection of the device must be carried out according to the respective country specific standards. Incorrect installation or adjustment could cause applicationally conditioned risks. Potential equalization - earthing The device must be grounded. The earthing can be carried out by the metallic process connection. The metallic parts of the device are electrically connected with the socket of the plug M12.
