General use Separate type Detector and
Related Equipment
General use separate type detector ZR22G can be used in combination with the probe protector
ZO21R (see Section 2.2.2).
2.2.1
ZR22G General use Separate type Detector
Sample Gas Temperature:0 to 700 °C (Probe only)
It is necessary to mount the cell using Inconel cell-bolts when the
temperature is greater than 600 °C.
700 to 1400 °C (with High Temperature Probe Adapter)
For high temperature sample gas, apply 0.15 m long probe and High
Temperature Probe Adapter ZO21P.
Sample Gas Pressure: -5 to +250 kPa (When the pressure in the furnace exceeds 3 kPa,
it is recommended that you compensate the pressure. When the
pressure in the furnace exceeds 5 kPa, you must perform pressure
compensation.) For 0.15 m probe, 0.5 to 5 kPa. No pressure fluctuation
in the furnace should be allowed.
Note:
When the detector is used in conjunction with a check valve and a ZA8F Flow Setting Unit,
the maximum pressure of sample gas is 150 kPa. When with a check valve and a ZR40H
Automatic Calibration Unit, it is 200 kPa. If the pressure of your sample gas exceeds these
limits, consult with Yokogawa.
Probe Length:
0.15, 0.4, 0.7, 1.0, 1.5, 2.0, 2.5, 3.0, 3.6, 4.2, 4.8, 5.4 m
Probe Material:
SUS 316 (JIS)
Ambient Temperature: -20 to +150 °C
Reference Gas System: Natural Convection, Instrument Air, Pressure Compensation
(other than for probe length 0.15 m)
Instrument Air System (excluding Natural Convection) :
Pressure; 200 kPa + the pressure inside the furnace (It is recommended
to use air which has been dehumidified by cooling to dew point -20 °C or
less, and dust or oil mist removed.)
Consumption; Approx. 1 Nl/min
Material in Contact with Gas: SUS 316 (JIS), Zirconia, SUS 304 (JIS) (flange), Hastelloy B,
(Inconel 600, 601)
