2.3 Detector Installation
CAUTION
The cell (sensor) at the tip of the detector is made of ceramic (zirconia). Do not drop the detector,
as inpact will damage it.
The gasket should be used on the flange surface to prevent gas leakage. The gasket material
should be heatproof and corrosion-proof.
The following should be taken into consideration when mounting the detector :
(1) Make sure the cell mounting screws (four pcs.) have not come loose.
(2) In a case where the detector is attached horizontally, the cable lead-in hole should face
downward.
