  • Page 9: Principle Of Operation

    There you will find the documentation and further information about the device. Principle of operation Application area LXRH, LXRC is a radar sensor for non-contact, continuous level measurement of liquids. Functional principle The instrument emits a continuous, frequency-modulated radar signal through its antenna.

  • Page 11: Mounting

    4 Mounting Mounting General instructions Ambient conditions The instrument is suitable for standard and extended ambient condi- tions acc. to DIN/EN/BS EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used indoors as well as outdoors. Note: Process conditions For safety reasons, the instrument must only be operated within the permissible process conditions.
  • Page 12 Please keep this in mind when mounting or making changes later. Reference plane The measuring range of the LXRH, LXRC physically begins with the antenna end. However, the min./max. adjustment begins mathematically with the reference plane, which is located differently depending on the sensor version.
  • Page 13 4 Mounting the vessel wall is expected. In such cases, we recommend repeating the false signal suppression at a later date with existing buildup. > 200 mm (7.87") Fig. 5: Mounting of the radar sensor on round vessel tops In vessels with conical bottom it can be advantageous to mount the device in the centre of the vessel, as measurement is then possible down to the lowest point of the bottom.
  • Page 14 Fig. 8: Thread mounting If the reflective properties of the medium are good, you can mount LXRH, LXRC on sockets longer than the antenna. The socket end should be smooth and burr-free, if possible also rounded. You will find recommended values for socket heights in the following illustration or the tables.
  • Page 15 4 Mounting The mounting location of the radar sensor should be a place where no Vessel installations other equipment or fixtures cross the path of the radar signals. Vessel installations, such as e.g. ladders, limit switches, heating spi- rals, struts, etc., can cause false echoes and impair the useful echo. Make sure when planning your measuring point that the radar sensor has a "clear view"...
  • Page 16 4 Mounting Fig. 12: Agitators Through the action of filling, stirring and other processes in the vessel, Foam generation compact foams which considerably damp the emitted signals may form on the medium surface. Note: If foams lead to measurement errors, you should use the biggest pos- sible radar antennas or as an alternative, sensors with guided radar.
