1.2 Conguration of Gas Lines
1.2.6.5 Internal Temperature Sensors
In the same way as pressure variations, va-
rying temperatures inuence the measuring
results: Higher temperature results in lower
gas density and thus in less molecules per
volume. To compensate temperature inu-
ence, internal temperature sensors can be
installed to electronically compensate tempe-
rature variations (
page 3-14 ,measurement
specication).
1.2.6.6 Internal Barometric Pressure Sensor
Varying atmospheric pressure has an inu-
ence also on the density of the gases applied
to the measuring system: Higher density cor-
relates with more molecules per volume and
thus inuences the measuring results.
To compensate such inuences. an internal
barometric pressure sensor can be installed.
It´s reading is used to electronically compen-
sate the atmospheric pressure variation (
measurement specication, page 3-14).
If such a sensor is installed in the unit, the
related menu shows the entry Internal (
6-91).
Depending on the conguration of the unit or
the demands of the application, temperature
sensors can measure the unit’s internal tem-
perature or selected measurement channel
components.
If such sensors are installed in the unit, this
is indicated in the installed options menu
(
6-85).
