    "serial number search". In addition to the type label outside on the instrument, the serial number is also available inside the instrument. 3.2 Principle of operation VEGACAP 27 is a level switch with fully insulated, capacitive Area of application electrode with screen segment and active tip for level detection.

  • Page 9: Operation

    The capacitance change is converted by the oscillator into a switching command. VEGACAP 27 is a compact instrument, i.e. it can be operated Supply 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.
