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).
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 (700 to 1400°C), 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 to use pressure compensated type. When the pressure
in the furnace exceeds 5 kPa, pressure compensated type is required.)
For 0.15 m probe, -0.5 to 5 kPa. No pressure fluctuation in the furnace
should be allowed.
No pressure fluctuation in the process should be allowed.
In case of Humidity Analyzer, -5 to 20 kPa
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
In case of Humidity Analyzer, 0.15 m is exclided
Probe Material: SUS 316 (JIS)
Ambient Temperature: -20 to 150°C
Reference Gas System: Natural Convection, Instrument Air, or 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
Wetted Material: SUS 316 (JIS), Zirconia, SUS304 (JIS) or ASTM grade 304 (flange),
Hastelloy B, (Inconel 600, 601)
Construction: Heater and thermocouple replaceable construction.
Non explosion-proof JIS C0920/equivalent to IP44D.
Equivalent to NEMA 4X/IP66 (Achieved when the cable entry is
completely sealed with a cable gland in the recirculation pressure
compensated version.)
