(1) Do not mount the probe with the tip higher than the probe base.
(2) If the probe length is 2.5 meters or more, the detector should be mounted vertically
(no more than a 5
Њ tilt).
(3) The detector probe should be mounted at right angles to the measurement gas flow or
the probe tip should point downstream.
Figure 3.1 illustrates an example of the probe insertion hole.

(Note)
When using the detector with pressure compensation, ensure that the flange
gasket does not block the reference air outlet on the detector flange. If the flange
gasket blocks the outlet, the detector cannot perform pressure compensation.
Where necessary, make a notch in the flange gasket.

3.1.3 Installation of the Detector
CAUTION
• The cell (sensor) at the tip of the detector is made of ceramic (zirconia). Do not drop
the detector, as impact will damage it.
• A gasket should be used between the flanges to prevent gas leakage. The gasket
material should be heatproof and corrosion-proof, suited to the characteristics of the
measured gas.
The following should be taken into consideration when mounting the general-use
detector:
<General-use detector>
(1) Make sure that the cell mounting screws (four) at the probe tip are not loose.
If a dust filter (see Section 2.6.1) is used, make sure it is properly attached to the
detector. Refer to Section 3.1.4 for installation of the dust filter.
(2) Where the detector is mounted horizontally, the calibration gas inlet and the refer-
ence gas inlet should face downward.
