1.1 Function and configuration
The pressure transmitter D80 is an efficient
instrument for pressure measurement. A dry
ceramic-capacitive CERTEC
® measuring cell
is used as pressure sensor element.
Pressure transmitter D80
Measuring cell: dry, ceramic-capacitive
Diaphragm: flush, ceramic
Series: flanged version
Standard application: Pressure measurement
of gases, vapours, liquids and dusts in all
areas of process engineering.
The pressure effects a capacitance change
in 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 dig-
ital 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)
