Note
Using an external pressure sensor
An external pressure sensor can process ambient or sample gas pressure values up to 3 bar
(abs.), regardless of the application. The following applies before you use an external pressure
sensor:
●
corresponding application.
● You can obtain additional information on the use of external pressure sensors from your
service partner: → Technical support (Page 113).
Note
OXYMAT 7 pressure correction
The OXYMAT 7 analyzer modules have an internal pressure sensor for correcting the effect
of pressure on the measured value.
In the case of OXYMAT 7 the pressure sensor is connected with the sample gas path and
therefore always measures the current sample gas pressure.
Note
ULTRAMAT 7 pressure correction
If you are using the analyzer module with atmospheric pressure sensor, make sure that the
pressure drop caused by the piping system at the sample gas outlet does not exceed 10 hPa
(large line diameter, short line length). In analyzer cabinets and analyzer enclosure, you can
connect the pressure transducer to the atmosphere in order to record only the atmospheric
pressure change.
Note
CALOMAT 7 pressure correction
With CALOMAT 7, you can implement required pressure correction using an external pressure
sensor.
