Figure 5-5: Oxygen Sensor - Principle of Operation

5.6.1.2. Operation within the GFC 7000TA Analyzer

The oxygen sensor option is transparently integrated into the core analyzer operation. All functions can be viewed or accessed through the front panel, just like the functions for CO2

∙The O2 concentration is displayed in the upper right-hand corner, alternating with CO2 concentration.

∙Test functions for O2 slope and offset are viewable from the front panel along with the analyzer’s other test functions.

∙O2 sensor calibration is performed via the front panel CAL function and is performed in a nearly identical manner as the standard CO2 calibration. See Section 3.3.1 for more details.

∙Stability of the O2 sensor can be viewed via the front panel (see Section 3.3.2.1).

∙A signal representing the currently measured O2 concentration is available.

The O2 concentration range is 0-100% (user selectable) with 0.1% precision and accuracy and is available to be output via the instrument’s analog output channel A3 (See Section 6.13.4).

The temperature of the O2 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 O2 TEMP.

The O2 sensor assembly itself does not have any serviceable parts and is enclosed in an insulated canister.

5.6.1.3. Pneumatic Operation of the O2 Sensor

∙Pneumatically, the O2 sensor is connected to the bypass manifold and draws a flow of about 120 cm³/min in addition to the normal sample flow rate and is separately controlled with its own critical flow orifice. Figure 5-8 shows the internal pneumatics of the GFC 7000TA with the O2 Sensor installed.
