3.1.6 Probe Insertion Hole
Includes those analyzers equipped with a probe supporter and probe protector.
When preparing the probe insertion hole, the following should be taken into consider-
ation:
CAUTION
• The outside dimension of detector may vary depending on its options. Use a pipe that
is large enough for the detector. Refer to Figure 3.4 for the dimensions.
• If the detector is mounted horizontally, the calibration gas inlet and reference gas inlet
should face downwards.
• The sensor (zirconia cell) at the probe tip may deteriorate due to thermal shock if
water drops are allowed to fall on it, as it is always at high temperature.
(1) Do not mount the probe with the tip higher than the probe base.
(2) The detector probe should be mounted at right angles to the measurement gas flow or
the probe tip should point downstream.
