If you have the TM2000 sensor without the sample bypass option:
•
Connect the sample gas from your process to the sample gas inlet on
the RCU (labeled Sample In on the RCU).
•
Connect the RCU outlet (labeled Sample Out on the RCU) to the inlet
of the TM2000 sensor (see Figure 3-7).

bypass).
The following steps are also required if you have the sample bypass op-
tion:
1. Connect the sample gas from your process to the sample inlet on the
TM2000 sensor (see Figure 3-8). This connection is located on the bot-
tom of the Bypass T-fitting, and is a 1/4” tube fitting.
2. Connect 1/8” tubing from the top of the Bypass T-fitting to the connec-
tion labeled Sample In on the RCU (see Figure 3-8).
3. Connect 1/8” tubing between the connection labeled Sample Out on
the RCU and the Inlet Valve Fitting on the TM2000 sensor (see Figure
3-8).
Figure 3-9 shows a flow diagram for the RCU and TM2000 sensor with
sample bypass.
