    VEGACAP 64 consists of the following components: Components Housing cover Housing with electronics Process fitting with electrode Fig. 1: VEGACAP 64 - with plastic housing Housing cover Housing with electronics Process fitting active screen segment active probe Type label The type label contains the most important data for identification and...

  • Page 8: Principle Of Operation

    In addition to the type label outside, you can also find the serial number on the inside of the instrument. 3.2 Principle of operation VEGACAP 64 is a level switch with fully insulated, capacitive electrode Application area with active screen segment and active tip for level detection.

  • Page 9: Operation

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

    Rain and condensation water can thus drain off. This applies mainly to outdoor mounting as well as installation in areas where high humidity is expected (e.g. through cleaning processes) or on cooled or heated vessels. Fig. 3: Measures against moisture penetration VEGACAP 64 • - Relay (DPDT)

  • Page 12: Mounting Instructions

    For this reason, do not use an overly long probe 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...
