3.1 Configuration

The scope of delivery encompasses:

• VEGABAR 14 process pressure transmitter

• angled plug connector and 2 mm screwdriver (for

instruments with connection acc. to DIN 43650)

• connection cable (for instruments with cable out-

let)

• Documentation

– this operating instructions manual

– test protocol.

3.2 Principle of operation

VEGABAR 14 is a process pressure transmitter for

gauge, absolute or vacuum pressure measurement.

The measured media can be gases, vapours and

liquids.

The CERTEC®measuring cell with rugged ceramic

diaphragm is the sensor element. The process pres-

sure causes a capacity change in the measuring cell

(via the ceramic diaphragm) which is converted into a

4... 20 mA signal.

VEGABAR 14 has a two-wire, 4 ... 20 mA electronics

module for power supply with 12 ... 30 V DC.
