ring range - permissible process pres-
sure
Due to the application, a measuring cell with higher measuring range
than the permissible pressure range of the process pressure can be
integrated. The permissible process pressure is stated with "process
pressure" on the type label, see chapter 3.1 "Configuration". For safety
reasons, this range must not be exceeded.
2.8 Environmental instructions
Protection of the environment is one of our most important duties. That
is why we have introduced an environment management system with

Packaging
3.2 Princi
VEGABAR 12 is a pressure transmitter for gauge pressure measure-
ment of neutral gases.
The sensor element is the CERTEC
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.
Two-wire electronics 4 … 20 mA for power supply and measured
value transmission over the same cable.
