Siting
Select a position where the intake is located in the main gas
stream. Gas temperature must be in the range 20 to 800 °C
Avoid positions where obstructions or bends prevent
Avoid positions where vibration levels induced by other plant
could result in mechanical failure of the probe.
To prevent acid dew-point corrosion, the probe mounting
flange and body must be thermally lagged if the temperature of

Maintain the probe terminal head temperature within the
CAUTION
Do not exceed the probe terminal head maximum operating
temperature. The probe must be sited in an area where:
• radiated heat from the process does not cause the
maximum temperature to be exceeded
Probe dimensions are shown in Figure 3, page 8. A clearance
