3.0 INSTALLATION SM425 INSTRUCTION MANUAL
3.1.3 Installation of the Detector
- The cell (sensor) at the tip of the detector is 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 1.9.1) is used, make sure it is properly attached to the detector. Refer
to Section 1.10.4 for installation of the dust filter.
2. Where the detector is mounted horizontally, the calibration gas inlet and the reference gas inlet
should face downward.
