VEGABAR 52 • 4 ... 20 mA/HART
Sensor element is the CERTEC
dependent on the process fitting also front-flush, abrasion-resistant
ceramic diaphragm. The process pressure causes a capacitance
change in the measuring cell via the ceramic diaphragm. This change
is converted into an appropriate output signal and outputted as
measured value.
®
measuring cell is also equipped with a temperature
The CERTEC
sensor. The temperature value can be displayed via the indicating and
adjustment module as well as processed via the signal output (with
digital versions).
As a standard feature, the CERTEC
a lateral, recessed seal.
Instruments with double seal have an additional front seal.
Instruments with hygienic fitting are equipped with a gap-free form
seal.
4 ... 20 mA/HART two-wire electronics for voltage supply and
measured value transmission on the same cable.
The supply voltage range can differ depending on the instrument
version.
The data for power supply are specified in chapter "Technical data".
The optional background lighting of the indicating and adjustment
module is powered by the sensor. A certain level of operating voltage
is required for this. You can find the exact voltage specifications in
chapter "Technical data".
The optional heating requires its own operating voltage. You can find
details in the supplementary instructions manual "Heating for indicat-
ing and adjustment module".
This function is generally not available for approved instruments.

3.3 Operation

The instrument can be adjusted with the following adjustment media:
With indicating and adjustment module
l
with the suitable VEGA DTM in conjunction with an adjustment
l
software according to the FDT/DTM standard, e.g. PACTware and
PC
with manufacturer-specific adjustment programs AMS™ or PDM
l
With a HART handheld
l

3.4 Packaging, transport and storage

Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
according to DIN EN 24180.
