Take note of safety instructions for Ex applications
Please note the Ex specic safety information which you can nd on our homepage www.vega.com/downloads under "Approvals" and which
comes with every instrument. In hazardous areas you should take note of the corresponding regulations, conformity and type approval certi-
cates of the sensors and power supply units. The sensors must only be operated on intrinsically safe circuits. The permissible electrical values
are stated in the certicate.

Measuring principle
Process pressure
37527-EN-190225
1 Measuring principle
Measuring principle
The pressure of the measured medium acts on the pressure measuring
cell, converting this pressure into an electronic signal. The ceramic-
capacitive CERTEC
®
as well as the metallic piezo and strain gauge
measuring cells are used.
VEGABAR 14
The sensor element is the ceramic CERTEC
®
measuring cell with rugged
ceramic diaphragm.

VEGABAR 17
With measuring ranges up to 40 bar, a piezoresistive sensor element with
internal transmission liquid is used. With measuring ranges from 100 bar,
a strain gauge (DMS) sensor element on the rear of the stainless steel
diaphragm (dry).

Advantages
The measuring instruments cover a particularly large measuring range,
from vacuum up to very high pressures. The integrated self-monitoring
enables a high operational safety. Process pressure transmitters using
the dry, ceramic-capacitive measuring cell oer special safety. They char-
acterize by high overload resistance and long-term stability.

Voltage supply
Depending on the version, the supply voltage and the current signal are
carried on the same two-wire connection cable.
The VEGA power supply units VEGATRENN 149AEx, VEGASTAB 690,
VEGADIS 371 as well as VEGAMET signal conditioning instruments are
suitable for power supply. When one of these instruments is used, a reli-
able separation of the supply circuits from the mains circuits according to
DIN VDE 0106 part 101 is ensured for the sensor.
•
Operating voltage
– 8 … 30 V DC
Connection cable
The sensors are connected with standard cable without screen. An outer
cable diameter of 5 … 9 mm ensures the seal eect of the cable entry.
If electromagnetic interference is expected which is above the test values
of EN 61326 for industrial areas, screened cable should be used.
Cable screening and grounding
If screened cable is necessary, the cable screen must be connected
on both ends to ground potential. If potential equalisation currents are
expected, the connection on the evaluation side must be made via a
ceramic capacitor (e.g. 1 nF, 1500 V).
