2. Specifications
2.2 General-use Separate-type Detector and Related
Equipment
The “Detector with dust protector” consists of ZR22G general-use separate-type detector
and ZH21B dust protector (refer to Section 2.2.2).
2.2.1 ZR22G General-use Separate-type Detector
Sample Gas Temperature: 0 to 700
Њ C (Probe only)
It is necessary to mount the cell using Inconel cell-bolts when the
temperature is 600
Њ C or greater.
Sample Gas Pressure: -5 to +20 kPa (When the pressure in the process exceeds 3kPa,
it is recommended that you compensate the pressure. When the pressure
in the process exceeds 5kPa, you must perform pressure compensation.)
No pressure fluctuation in the process should be allowed.
Probe Length: 0.4, 0.7, 1.0, 1.5, 2.0, 2.5, 3.0 m
Probe Material: SUS 316 (JIS)
Ambient Temperature: -20 to +150
Њ C
Reference Air System: Natural Convection, Instrument Air
Instrument Air System (excluding Natural Convection):
Pressure; 200 kPa + the pressure inside the dryer, (It is recommended to
use air which has been dehumidified by cooling to dew point -20
Њ C or
less, and with dust or oil mist removed.)
Consumption; Approx. 1Nl/min
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 Auto Calibration Unit, it is
200 kPa. If the pressure of your sample gas exceeds these limits, consult
with Yokogawa.
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 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.)
Terminal Box Case: Material; Aluminium alloy
Terminal Box Paint Color:
Case; Mint green (Munsell 5.6BG3.3/2.9)
Cover; Mint green (Munsell 5.6BG3.3/2.9)
Finish: Polyurethane corrosion-resistant coating
Gas Connection: Rc 1/4 or 1/4 FNPT
Wiring Connection: G1/2, Pg13.5, M20 by 1.5mm, 1/2 NPT
Installation: Flange mounting
