3.2 Installation of High Temperature Detector
(ZR22G-015)
This detector is used with the High Temperature Probe Adapter (Model ZO21P-H) when the
The following should be taken into consideration when installing the detector:
(1) Easy and safe access to the detector for checking and maintenance work.
(2) Ambient temperature of not more than 150°C and the terminal box should not be exposed to
radiant heat.
(3) A clean environment without any corrosive gases.
(4) No vibration.
3.2.1 Usage of the High Temperature Probe Adapter
(ZO21P-H)
During analysis, the surface temperature of the probe adapter should be within the range from
more than the dew point of the sample gas and 300°C or less to prevent ejector clogging, gasket
deterioration or bolt scoring.
Where the dew point of the sample gas is not known, keep within the range of more than 200°C
to less than 300°C.
The temperature shall be measured at the probe in the probe adapter and the surface of the blind
When the surface temperature is not within the above range, the following measures can be
taken to change the temperature.
<When the surface temperature exceeds 300°C>
of the sample gas.
Refer to Section
“2.7.3 Ejector Assembly for High Temperature (E7046EC, E7046EN)”,
(2) When the furnace pressure is positive, close the needle valve for the sample gas outlet to
“4.1.4 Piping to the High Temperature
Probe Adapter”, Piping to the High Temperature Probe Adapter.
