Safety information
Please read this manual carefully, and also take
note of country-specific installation standards
(e.g. the VDE regulations in Germany) as well
as all prevailing safety regulations and acci-
dent prevention rules.
For safety and warranty reasons, any internal
work on the instruments, apart from that in-
volved in normal installation and electrical con-
nection, must be carried out only by qualified
VEGA personnel.

Product description
1 Product description
1.1 Function and configuration
The pressure transmitter D84 is an efficient
instrument for hydrostatic level measurement.
A dry ceramic-capacitive CERTEC
®
measuring cell is used as pressure sensor
element.
Pressure transmitter D84
Measuring cell: dry, ceramic-capacitive
Diaphragm: flush, ceramic
Series: flanged version
Standard application: All kind of level
measurements, best suited for food
processing and pharmaceutical industries.
The pressure effects a capacitance change
on 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 electronic module with
microcontroller. Precise, high-resolution digi-
tal processing of measurement data ensures
excellent technical data.
To improve reliability, the functionality of im-
portant electronic components is continu-
ously checked, and internal parameters such
as sensor value, temperature and operating
voltage are closely monitored.
Output signal
The output signal is transferred as a digital or
analogue signal from the pressure transmitter
to the signal conditioning instrument:
• analogue output signal
- unstandardised (in conjunction with
VEGA signal conditioning instrument)
- 4 … 20 mA standardised
• digital output signal (VBUS) for connection
to a digital VEGA signal conditioning instru-
ment (VEGAMET 514V, 515V or VEGALOG
571)
