SENSOR OPERATION WITHIN THE T100 ANALYZER
The oxygen sensor option is transparently integrated into the core analyzer operation.
All functions can be viewed or accessed through the front panel display, just like the
functions for SO
2
.
The O
2
concentration is displayed below the SO
2
concentration.
Test functions for O
2
slope and offset are viewable from the front panel along with
the other test functions of the analyzer.
O
2
sensor calibration is performed via the front panel CAL function and is
performed in a nearly identical manner as the standard SO
2
calibration. Refer to
Section 9.10.1 for more details.
Stability
of the O
2
sensor can be viewed via the front panel (refer to Section
9.10.1.3).
The O
2
concentration range is 0-100% (user selectable) with 0.1% precision and
accuracy.
The temperature of the O
2
sensor is maintained at a constant 50°C by means of a PID
loop and can be viewed on the front panel as test function O
2
TEMP.
The O
2
sensor assembly itself does not have any serviceable parts and is enclosed in an
insulated canister.
