sensor. This includes the following:
•

Sample Inlet Probe Installation

•
Probe Heater Installation (optional)

Remote Calibration Unit Mounting and Plumbing (optional)
sample Inlet Probe Installation

NOTE
The sample inlet probe is how the sample gas gets to the sensor. Aspira-
tor air within the sensor is used to pull process gas from the sample probe
into the sensor. The sample inlet probe is identified by the threads on both
ends.
•
Figure 3-1 shows how to install the standard 1/8" NPT probe.
•
Figure 3-2 shows how to install a ceramic or long probe.
•
Figure 3-3 shows port locations on the rear of the sensor.
You can connect the probe to the sensor before mounting the sensor un-
less the probe is either very long or made of ceramic. In that case you
should mount the sensor first and then install the probe.
For some applications, you must first connect the sample inlet probe
to the sensor before mounting the sensor. The same applies if you are
installing the probe heater or exhaust tube. Therefore, these subjects
are discussed before the sections on how to mount the sensor to the
process.
