  • Page 8: Principle Of Operation

    Principle of operation Area of application VEGACAP 62 is a point level sensor for use in all areas of industry. The partly insulated probe is suitable for the measurement of bulk solids and liquids.

  • Page 9: Operation

    The capacitance change is converted by the electronics module into a switching command. Voltage supply Depending on your requirements, VEGACAP 62 with two-wire elec- tronics can be connected to different signal conditioning instruments. Compatible signal conditioning instruments are listed in chapter "Technical data". The data for power supply are specified in chapter "Technical data".

    The protective cover protects the sensor housing against soiling and intense heat from solar radiation. You will find additional information in the supplementary instructions manual "Protective cover" (Document-ID 34296). Flanges Screwed flanges are available in different versions according to the following standards: DIN 2501, EN 1092-1, BS 10, ASME B 16.5, JIS B 2210-1984, GOST 12821-80.

    Fig. 4: Measures against moisture ingress Transport Do not hold VEGACAP 62 on the probe. Especially with heavy flange versions or long rod versions, the sensor can be damaged simply by the weight of the instrument. VEGACAP 62 • - two-wire...

  • Page 12: Mounting Instructions

    Agitators and fluidization Due to the effects of agitators, equipment vibration or similar, the level switch can be subjected to strong lateral forces. For this reason, do not use an overly long electrode for VEGACAP 62, but check if you can mount a short level switch on the side of the vessel in horizontal position. Extreme vibration caused by the system, e.g. due to agitators or turbulence in the vessel from fluidisation, can cause the probe of VEGACAP 62 to vibrate in resonance.
  • Page 13 The probe must be mounted in a way that takes the arrangement of the filling and emptying apertures into account. To compensate measurement errors caused by the material cone in cylindrical vessels, the sensor must be mounted at a distance of d/6 from the vessel wall. VEGACAP 62 • - two-wire...

    After connecting to voltage supply or after a voltage recurrence, the instrument passes a certain switch on routine. By lowering the current value when switching on, the instrument can output briefly a fault message. I/mA 20,5 < 2,3 Fig. 13: Warm-up reaction Measured value VEGACAP 62 • - two-wire...

  • Page 19: Setup

    Note: As a rule, always set the mode with the mode switch of the signal conditioning instrument before starting setup VEGACAP 62. The switching output will change if you set the mode switch afterwards. This could possibly trigger other connected instruments or devices.
