Page 8: Principle Of Operation
Principle of operation Area of application VEGACAP 66 is a point level sensor for use in non-abrasive liquids and bulk solids. The cable probe is fully insulated and the proven mechanical con- struction offers high functional safety. -
Page 9: Operation
The capacitance change is converted by the electronics module into a switching command. Voltage supply VEGACAP 66 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. a warning system,... -

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 66 • - contactless electronic switch... -
Page 11: Mounting
You can find the specifications in chapter "Technical data" and on the nameplate. Switching point In general, VEGACAP 66 must be mounted vertically. The instrument must be mounted in such a way that the probe is at the height of the requested switching point. Welding work Before beginning the welding work, remove the electronics module from the sensor. -
Page 12: Mounting Instructions
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 66, but check if you can mount a short level switch on the side of the vessel in horizontal position. Inflowing medium If the instrument is mounted in the filling stream, unwanted false measurement signals can be generated. - 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.
