Model 9110T NOx Analyzer

Principles of Operation

Note

The PMT temperature is maintained by a separate control loop that does

 

not involve the relay PCA (see Section 13.5.2).

 

13.3.4.5. Thermocouple Inputs and Configuration Jumper (JP5)

Although the relay PCA supports two thermocouple inputs, the current 9110T analyzers only utilize one. It is used to sense the temperature of the NO2 NO converter.

This single thermocouple input is plugged into the TC1 input (J15).

TC2 (J16) is currently not used (see Figure 13-15 for location of J15 and J16).

The type and operating parameters of this thermocouple are set using a jumper plug (JP5). The default configuration for this thermocouple is:

Type-K

Temperature compensated for Type-K

Isolated
