General Use Separate Type Detector And Related Equipment; Zr22G General Use Separate Type Detector - YOKOGAWA ZR22G User Manual

2.2 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
In case of Humidity Analyzer, the "Detector with dust protector" consists of ZR22G general-use
separate-type detector and ZH21B dust protector (refer to Section "2.2.3 ZH21B Dust Protector").

STANDARD SPECIFICATIONS (Oxygen
Analyzer)
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.
For high temperature sample gas (700
to 1400°C), apply 0.15 m length probe
and High Temperature Probe Adapter
ZO21P-H.
Sample Gas Pressure: - 5 to + 250 kPa (No
pressure fluctuation in the furnace
should be allowed.)
When the pressure in the furnace
exceeds 3 kPa, it is recommended to
use pressure compensated type.
When the pressure in the furnace
exceeds 5 kPa, pressure compensated
type is required.
For 0.15 m probe length, - 0.5 to + 5
kPa.
Note: When the detector is used in conjunction with a check
valve and the ZA8F Flow Setting Unit, the maximum
pressure of sample gas is 150 kPa.
When with a check valve and the 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: SUS316
Ambient Temperature: -20 to +150°C
Reference Gas System: Natural Convection,
Instrument Air, Pressure compensated
(other than for probe length 0.15 m)
Instrument Air System (excluding Natural
Convection) It is recommended to use
air which has been dehumidified by
cooling to dew point -20°C or less, and
dust or oil mist are removed.
