3.1.6 Probe Insertion Hole
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 3.3 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.
Figure 3.3 illustrates an example of the probe insertion hole.
