2.2 General-use Separate-type Detector and Related
Equipment
2.2.1
ZR22G General-use Separate-type Detector
IM 11M12A01-02E
General-use separate-type detector ZR22 can be used in combination with the probe
protector ZO21R-L (see Section 2.2.2).
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 tempera
ture Probe Adapter ZO21P-H.
Sample Gas Pressure: -5 to +250 kPa (When the pressure in the furnace exceeds 3 kPa,
it is recommended that you compensate for this pressure. When the pressure in
the furnace exceeds 5 kPa, you must perform pressure compensation.)
For 0.15m probe, 0.5 to 5kPa.
No pressure fluctuation in the furnace should be allowed.
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 Air 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 had
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)
Construction: Heater and thermocouple replaceable construction. Non explosionproof.
Equivalent to NEMA 4X/IP66 (recirculation to furnace with pressure compen
sation only)
Terminal Box Case: Material; Aluminium alloy
Terminal Box Paint Color:
Case; Off-white (Munsell 0.6GY3.1/2.0)
Cover; Moss green (Munsell 2.5Y8.4/1.2)
Finish: Polyurethane corrosion-resistant coating
Gas Connection: Rc1/4 or 1/4FNPT
Wiring Connection: G1/2, Pg13.5, M20 by 1.5 mm, 1/2 NPT
