The Sensor Enclosure

The sensor enclosure, which is shown in Figure 1-2 below, houses the

sample measurement components. The functions of these components

are as follows:

• a zirconium oxide (zirconia) oxygen sensor converts the oxygen

concentration of the sample gas into a mV output signal.

• a sensor furnace heats the oxygen sensor and the sample gas to the

optimum temperature of 700°C.

• a thermocouple precisely regulates the temperature of the oxygen

sensor and the sample gas.

• an inlet needle valve and an outlet flowmeter adjust the sample gas

flow to 1,000 ± 150 cc/min (2.1 ± 0.3 SCFH).
