Linearity : (Excluding standard gas tolerance) (See Note 1)
(Use oxygen of known concentration (in the measuring range) as the zero and span
calibration gas.)

Response Time : Response of 90% within 5 second. (Measured after gas is introduced
from calibration-gas inlet and analog output start changing.)
(Note1) These tolerances do not apply to the pressure compensated version, or where
natural convection is used for the reference air.
2.1.2 ZR202G Integrated-type Zirconia High-temperature Humidity 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 V)
Digital Communication (HART) : 250 to 550 V, 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 7008 C
It is necessary to mount the cell using Inconel cell-bolts when the temperature
measures more than 6008 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, 3.0m
Probe Material : SUS 316 (JIS)
Ambient Temperature : -20 to +558 C (- 5 to +708 C on the case surface)
Storage Temperature : -30 to +708 C
Humidity Ambient : 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 with-
stand 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.
Safety and EMC conforming standards
Safety : EN61010-1
