93 Product descriptionVEGACAP 64 • Transistor (NPN/PNP)30014-EN-170503123Fig. 3: Functional principle - Plate capacitor1 Distance between the electrode surfaces2 Size of the electrode surfaces3 Type of dielectric between the electrodesThe probe and the vessel wall are the capacitor plates. The measuredproduct is the dielectric. Due to the higher dielectric constant of theproduct compared to air, the capacitance increases as the probe isgradually covered.The capacitance change is converted by the electronics module intoa switching command.VEGACAP 64 is a compact instrument, i.e. it can be operated withoutexternal evaluation system. The integrated electronics evaluates thelevel signal and outputs a switching signal. With this switching signal,a connected device can be operated directly (e.g. a warning system,a pump etc.).The data for power supply are specified in chapter "Technical data".3.3 AdjustmentThe probe can be adapted to the dielectric constant of the productdirectly on the electronics module.A switching command can be triggered when the probe is covered orlaid bare.On the electronics module you will find the following display andadjustment elements:• Signal lamp for indication of the switching condition (green/red)• Potentiometer for switching point adaptation• DIL switch for measuring range selection• DIL switch for mode adjustment3.4 Packaging, transport and storageYour instrument was protected by packaging during transport. Itscapacity to handle normal loads during transport is assured by a testbased on ISO 4180.The packaging of standard instruments consists of environment-friendly, recyclable cardboard. For special versions, PE foam or PEVoltage supplyPackaging
