Standard Specifications
Measured Object: Oxygen concentration in combustion exhaust gas and mixed gas
(excluding inflammable gases, may not be applicable corrosive gas such
as ammonia, chlorine is present-check with YOKOGAWA)
The sampling gases containing a corrosive gas such as ammonia or
chlorine may be applicable to our oxygen gas analyzer. In this case,
contact with YOKOGAWA and its agency.
(In case of Humidity Analyzer, Water vapor (in vol%) in mixed gases (air
and water vapor))
Measurement System: Zirconia system
Measurement Range: 0.01 to 100 vol%O

O or 0 to 1.000 kg/kg)
Output Signal: 4 to 20 mA DC (maximum load resistance 550 Ω)
Setting Range: Any setting in the range of 0 to 5 through 0 to 100 vol%O
2
(in 1 vol%O

),
or partial range
In case of Humidity Analyzer,
Moisture quantity; 0 to 25 through 0 to 100 vol% H

O), or partial range.
Mixture ratio; 0 to 0.2 through 0 to 1.000 kg/kg (in 0.001 kg/kg), or
partial range.
Digital Communication (HART): 250 to 550 Ω, depending on number of field devices connected
to the loop (multi-drop mode).
Note: HART is a registered trademark of the HART Communication Foundation.
Display Range: Oxygen concentration; 0 to 100 vol%O

In case of Humidity Analyzer,
Moisture quantity; 0 to 100 vol% H

O, Mixture ratio; 0 to 1 kg/kg, Relative
humidity; 0 to 100% RH (Note), Dew point; -40 to 370°C (Note)
Note: These values are affected by temperature and absolute pressure, So accurate temperature and
pressure values must be inputted to the converter.
Warm-up Time: Approx. 20 min.
These characteristics are calculated by oxygen concentration measured in air which include
water vapor.
