CO Detector PCA

The detector PCA amplifies the signal from the IR detector and it includes the trim pot to adjust the

detector gain.

1.5.4.4 Pressure Sensor PCA

Refer to Figure 7 for the location of pressure sensor PCA. The pressure sensor PCA has an absolute-

pressure transducer that is mounted on the measurement cell and sealed via a gasket. This allows the

pressure sensor PCA to measure the sample air pressure in the measurement cell. This pressure

reading is used to verify sample flow and correct measurement readings for pressure variations.

1.5.4.5 Orifice and Sintered Filter

Refer to Figure 7 for the location of orifice and sintered filter. The critical orifice is made of a high

precision stainless steel and sapphire, which is located Inside the Kynar fitting on the end of the

measurement cell. The critical orifice is a simple device that operates at a set temperature and requires

minimal maintenance, it will passively keep the volume flow rate constant at a known value.
