T he type label contains the most important data for identification and
use of the instrument:
l S ensor type
l A rticle number instrument
l T echnical data: Measuring range, process pressure, process
temperature, signal output, voltage supply, protection, protection
class
l O rder number
l A rticle numbers documentation
l S erial number
W ith the serial number, you can access the delivery data of the
instrument via www.vega.com, "VEGA Tools" and "serial number
search". In addition to the type label outside, you can also find the
serial number on the inside of the instrument.
3.2 Principle of operation
VEGABAR 63 is a pressure transmitter for measurement of over-
pressure, absolute pressure or vacuum. Measured products are
gases, vapours and liquids in measuring ranges up to 4000 bar
(400 MP
a); with front-flush version also viscous liquids in measuring
ranges up to 600 bar (60 MPa).
T he process pressure acts on the sensor element via the stainless
steel diaphragm. The process pressure causes a resistance change
which is converted into a corresponding output signal and outputted as
measured value.
