    Product description Technical data Article numbers, documentation 3.2 Principle of operation SITRANS LVL100 is a point level sensor with tuning fork for Area of application level detection. It is designed for industrial use in all areas of process technology and can be used in liquids.

  • Page 9: Operation

    Data for power supply are specified in chapter "Technical data". 3.3 Operation The switching status of SITRANS LVL100 can be checked with closed housing (signal lamp). Products with a density > 0.7 g/ cm³ (0.025 lbs/in³) can be detected. 3.4 Storage and transport Your instrument was protected by packaging during transport.

  • Page 10: Mounting

    The switching point refers to water (1 g/cm³/0.036 lbs/in³). When mounting SITRANS LVL100, make sure that this marking is at the height of the requested switching point. Keep in mind that the switching point of the instrument is shifted if the medium has a density other than water.
  • Page 11 This applies mainly to mounting outdoors, in areas where moisture is expected (e.g. by cleaning processes) or on cooled or heated vessels.
