3. Installation
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.
• If the detector is mounted horizontally, the calibration gas inlet and reference gas inlet
should face downwards.
• 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:
(1) Make sure that the cell mounting screws (four) at the probe tip are not loose.
(2) Where the detector is mounted horizontally, the calibration gas inlet and the refer-
ence gas inlet should face downward.
3.1.4 Installation of ZH21B Dust Protector
(1) Place the gasket between the flanges and mount the dust protector in the probe
insertion hole.
(2) Make sure that the cell assembly mounting screws (four) at the probe tip are not
loose.
(3) Mount the detector so that the calibration gas inlet and the reference gas inlet face
downward.
