Ceramic probe or long probe installation
If you ordered a long probe or a ceramic probe, connect the probe to the
sensor as follows:
1. Mount the sensor. See the "Sensor Mounting" section later in this
chapter for help. Note, however, that if you are installing the probe
heater or exhaust tube, you must connect these items to the sensor
before mounting the sensor.
2. Remove the sensor enclosure to expose the sensor components.
3. Remove the probe inlet hook from the sensor as shown in Figure 3-2.
To do this, loosen the fitting connecting the inlet hook to the aspirator
block and pull the hook out of the sensor.
4. Unscrew the bushing that was plugged into the sensor inlet port and
discard. The probe comes with its own bushing and fitting.
5. Thread the sensor probe into the sensor inlet port on the sensor
backplate. Do not let the probe hit against the Thermox-provided pipe
nipple as you insert the probe into the process. If inserting a ceramic
probe, you must slowly insert it into a hot process to prevent the
probe from cracking due to thermal shock.
6. Reconnect the probe inlet hook to both the sensor backplate and the
aspirator block and tighten.
