7.14Remote Sensor Installations
The oxygen sensor for a DF Series analyzer may be installed outside of the
analyzer cabinet (if equipped with this option). Areas of high convected or
radiated heat must be avoided.
If installed outdoors the sensor enclosure must be shielded from the sun to
avoid overheating. In addition, a heater must be installed in the enclosure in
areas where the temperature goes below freezing. (See page 36)
Care must be taken to use high quality cable and techniques when making
remote connections. Refer to Table 6 and Table 7 for wire sizes and lengths.
Following are three remote sensor configurations and wiring diagrams. Contact
Servomex for additional information on remote sensor installations.
CAUTION
Always use a backing wrench when connecting the gas sample line
to a remote sensor.
