(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° tilt).
(3) The detector probe should be mounted at right angles to the sample gas ow or the probe
tip should point downstream.

When using the detector with pressure compensation, ensure that the ange gasket does not block the reference gas outlet on
the detector ange. If the ange gasket blocks the outlet, the detector cannot perform pressure compensation.
Where necessary, make a notch in the ange gasket. Conrm the outside dimensions of the detector in Section 2.2 before
installation.
Figure 3.1 illustrates an example of the probe insertion hole.
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 anges to prevent gas leakage. The gasket material
should be heatproof and corrosion-proof, suited to the characteristics of the sample 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 bolts) at the tip of the detector are not loose.
If a dust lter (see Section 2.7.1) is used, make sure it is properly attached to the detector.
Refer to Section 3.1.4 for installation of the dust lter.
(2) Where the detector is mounted horizontally, the calibration gas inlet and the reference gas
inlet should face downward.
