VEGACAP 62 • - transistor (NPN/PNP)

30006-EN-130916

Fig. 3: Functional principle - Plate capacitor

1 Distance between the electrode surfaces

2 Size of the electrode surfaces

3 Type of dielectric between the electrodes

The probe and the vessel wall are the capacitor plates. The measured

product is the dielectric. Due to the higher dielectric constant of the

product compared to air, the capacitance increases as the probe is

gradually covered.

The capacitance change is converted by the electronics module into

a switching command.

VEGACAP 62 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,

a pump etc.).

3.3 Operation

The probe can be adapted to the dielectric constant of the product

directly on the electronics module.

A switching command can be triggered when the probe is covered or

laid bare.

adjustment 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 adjustment

3.4 Storage and transport

Your instrument was protected by packaging during transport. Its

capacity to handle normal loads during transport is assured by a test

based on ISO 4180.

The packaging of standard instruments consists of environment-

friendly, recyclable cardboard. For special versions, PE foam or PE
