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
(68 to 1472 °F). The surface temperature of the duct must not
exceed 400 °C (752 °F).
Avoid positions where obstructions or bends prevent
installation (and subsequent removal) of the probe.
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
the flue wall and probe mounting flange is <150 °C (<302 °F)
when the process is operating.

* The probe can withstand 35 kPa (5.1 psi) – positive or negative pressure. Pressure compensation is required above 5 kPa (0.7 psi) –
the transmitter can supply fixed pressure compensation.

Maintain the probe terminal head temperature within the
range –20 to 70 °C (–4 to 158 °F).
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
of at least 25 mm (1 in) in excess of the overall probe length is
necessary to enable installation or removal.
