    During work on and with the device the required personal protective equipment must always be worn. Appropriate use The VEGACAP 64 is a sensor for point level detection. You can find detailed information about the area of application in chapter "Product description". Operational reliability is ensured only if the instrument is properly used according to the specifications in the operating instructions manual as well as possible supplementary instructions.

    The VEGACAP 64 consists of the components: • Process fitting with probe • Housing with electronics • Housing lid Fig. 1: VEGACAP 64, rod version with plastic housing Housing lid Housing with electronics 3 Process fitting Type label The type label contains the most important data for identification and use of the instrument: VEGACAP 64 • Transistor (NPN/PNP)

  • Page 8: Principle Of Operation

    Principle of operation Application area VEGACAP 64 is a point level sensor for use in non-abrasive liquids and bulk solids. The rod probe is fully insulated and due to its construction is suitable for all viscous and adhesive products.

  • Page 9: Adjustment

    The capacitance change is converted by the electronics module into a switching command. Voltage supply VEGACAP 64 is a compact instrument, i.e. it can be operated without external evaluation system. The integrated electronics evaluates the level signal and outputs a switching signal. With this switching signal, a connected device can be operated directly (e.g.

    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. You can find additional information in the supplementary instructions manual "Flanges according to DIN-EN-ASME-JIS". VEGACAP 64 • Transistor (NPN/PNP)

    (e.g. through cleaning processes) or on cooled or heated vessels. To maintain the housing protection, make sure that the housing lid is closed during operation and locked, if necessary. Make sure that the degree of contamination specified in chapter "Technical data" meets the existing ambient conditions. VEGACAP 64 • Transistor (NPN/PNP)

  • Page 13: 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 64, 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 64 to vibrate in resonance.
  • Page 14 Torque with PTFE plated To compensate the material-specific preload loss due to sealing ma- flanges terials, you have to additionally use disc springs for fastening flange screws on PTFE coated flanges. Tighten the screws moderately with the torque stated in the technical data. Depending on the process and ambient conditions, this value can vary. In individual cases you should occasionally check the tightness on site. VEGACAP 64 • Transistor (NPN/PNP)

  • Page 15: Connecting To Power Supply

    Voltage supply Take note of the general installation regulations. As a rule, connect VEGACAP 64 to vessel ground (PA), or in case of plastic vessels, to the next ground potential. On the side of the instrument housing there is a ground terminal between the cable entries. This connection serves to drain off electrostatic charges.

    Note: As a rule, always set the mode with the mode switch (3) before start- ing setup VEGACAP 64. The switching output will change if you set the mode switch (3) afterwards. This could possibly trigger other con- nected instruments or devices.
  • Page 21 In some cases the lowest range (range 1 = highest sensitivity) is not sufficient to adjust the full switch point. This would make another filling procedure necessary. For this reason we recommend setting and noting the empty switching point in all three meas. ranges. Set the meas. range se- VEGACAP 64 • Transistor (NPN/PNP)
