<2. Specifications>
2-2
IM 11M12A01-04E
Drift:
(Excluding the first two weeks in use)
(Excluding the case where the reference gas is by natural convection.)
Both zero and span ± 2% Maximum value of set range/month
Response Time:
Response of 90% within 5 seconds. (Measured after gas is introduced from
calibration gas inlet and analog output starts changing.)
2.1.2 ZR202G Integrated type Zirconia Oxygen Analyzer
Can be operated in the field without opening the cover using optical switches.
Display:
6-digit LCD
Switch:
Three optical switches
Output Signal:
4 to 20 mA DC, one point (maximum load resistance 550 Ω)
Digital Communication (HART): 250 to 550 Ω, depending on quantity of field devices connected to the
loop (multi-drop mode).
Note: HART is a registered trademark of the HART Communication Foundation.
Contact Output Signal: Two points (one is fail-safe, normally open)
Contact Input Signal: Two points
Sample Gas Temperature: 0 to 700°C
It is necessary to mount the cell using Inconel cell-bolts when the
temperature measures more than 600°C.
High-temperature service ― greater than 700°C ― is not available.
Sample Gas Pressure: -5 to +250 kPa (When the pressure in the furnace exceeds 3 kPa, it is
recommended to compensate the pressure. When the pressure in the
furnace exceeds 5 kPa, you must perform pressure compensation.)
No pressure fluctuation in the furnace be allowed.
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 ZR20H Automatic Calibration Unit, it is 200 kPa. If the pressure of your sample
gas exceeds these limits, consult with Yokogawa.
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 +55°C (- 5 to +70°C on the case surface)
Storage Temperature: -30 to +70°C
Humidity Range:
0 to 95%RH (non-condensing)
Installation Altitude:
2000 m or less
Category based on IEC 1010: II (Note)
Pollution degree based on IEC 1010: 2 (Note)
Note: Installation category, called over-voltage category, specifies impulse withstand voltage. Category II is for electrical equipment.
Pollution degree indicates the degree of existence of solid, liquid, gas or other inclusions which may reduce dielectric strength.
Degree 2 is the normal indoor environment.
Power Supply Voltage: Ratings; 100 to 240 V AC
Acceptable range; 85 to 264 V AC
Power Supply Frequency: Ratings; 50/60 Hz
Acceptable range; 45 to 66 Hz
Power Consumption: Max. 300 W, approx. 100 W for ordinary use.
