Appendix F: TC Sensors
Overview
The TC sensors are used to monitor high levels of combustible gas. This
appendix describes the EAGLE 2’s TC sensor and includes instructions to
use an EAGLE 2 that has a TC sensor installed. It also includes instructions
to calibrate and replace a TC sensor.
Table 20: TC Sensor Specifications
Description
The TC sensor is installed in a single sensor flow chamber which is located in
the area next to the standard 4-sensor flow chamber. This area can
accommodate up to three single sensor flow chambers. Figure 37 below
illustrates a typical TC sensor location in front of the pump. The TC flow
chamber may also be installed in one of the other two sensor chamber
locations depending on the particular version of the EAGLE 2. Some TC
sensor instrument configurations do not include the 4-sensor flow chamber.
