Sample Gas Temperature: 0 to 700
؇ C (Probe only)
It is necessary to mount the cell using Inconel cell-bolts when the
temperature is 600
؇C or greater.
700 to 1400
؇C (with High Temperature Probe Adapter)
For high-temperature sample gas, apply 0.15 m length probe and
High temperature Probe Adapter ZO21P-H.
Sample Gas Pressure: -5 to +5 kPa
No pressure fluctuation in the furnace should be allowed.
Probe Length: 0.15, 0.4, 0.7, 1.0, 1.5, 2.0 m
Probe Material: SUS 316 (JIS)
Ambient Temperature: -20 to +60
؇C (-20 to +150؇C on the terminal box surface)
Reference Air System: Instrument Air
Instrument Air System:
Pressure; 50 kPa + the pressure inside the furnace
150 kPa + the pressure inside the furnace with autocalibration unit
or check valve. (It is recommended to use air which has been
dehumidified by cooling to dew point -20
؇C or less, and had dust or
oil mist removed.)
Consumption; Approx. 1 Nl/min
Material in Contact with Gas: SUS 316, SUS 316L (JIS), Zirconia, SUS 304 (JIS)
(flange), Hastelloy B, (Inconel 600, 601)
Construction: Heater and thermocouple replaceable construction.
NEMA 4X/IP66 (Achieved when pipes are installed at calibration
gas and reference air inlets and pipe is installed so that reference air
can be exhausted to clean atmosphere. Excluding probe top. And
achieved when the cable entry is completely sealed with a cable
gland.)
Terminal Box Case: Material; Aluminum alloy
