1.1 Function and configuration

VEGABAR 40 process pressure transmitters are efficient instruments for process pressure measurement. As pressure sensor element, the dry ceramic-capacitive measuring cell CERTEC sure effects via the diaphragm a capacitance change within the measuring cell. This capacitance change is detected by an ASIC (application specific integrated circuit) and converted into a pressure-proportional signal by the integrated oscillator with microcontroller. In addition, the process temperature is detected via a sensor element and converted into a temperature-dependent signal. Precise, high-resolution digital processing of measurement data ensures excellent technical data.

The electronics module is powered by a Profibus DP - PA segment coupler. The measured pressure is transmitted via the bus cable as a digital signal to the processing system and can be displayed on the indicating module or the external indicating instrument VEGADIS 10.

The following adjustment variants are available:

- adjustment module directly on VEGABAR

- adjustment modules in external housing (VEGADIS 10)

- via PC with adjustment software VEGA Visual Operating (VVO)

is used. The process pres-

1.2 Self-monitoring

To improve reliability, the functionality of important electronic components is continuously checked, and internal parameters such as sensor value, temperature and operating voltage are closely monitored.

VEGABAR 40 with the ceramic CERTEC measuring cell offers the advantage of continuous self-monitoring. The measuring and reference capacitances of the measuring cell constitute a predefined ratio over the entire measuring range. Any deviation from these data is a reliable indicator of a malfunction of the measuring cell.

If errors or malfunctions are detected during these routines, fault signals are triggered according to the Profibus PA specification.

The instrument profile of VEGABAR follows the profile specification version 3.0. The instrument master file (GSD) is available as download on the homepage of VEGA (www.vega-g.de).

Note the following instructions for electrical connection:

- Connection must be made according to the specific installation standards (e.g. in Germany acc. to the VDE-regulations).

- Electrical connection must have a protective measure against polarity reversal.

- The connection of field instruments is generally made via T-adapters on stubs.

- Screened cable is recommended for connection (cable types see chapter "1.3 Technical data“). The shielding must be grounded on both ends (on the T-adapter and on VEGABAR).

- For use in Ex areas, the installation regulations must be observed.
