2.1 General Specications
2.1.1 Standard Specications
Measured Object: Oxygen concentration in combustion exhaust gas and mixed gas
(excluding inammable gases, may not be applicable corrosive gas such
as ammonia 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.
Measurement System: Zirconia system
Oxygen concentration: 0.01 to 100 vol% O
2
Output Signal: 4 to 20 mA DC (maximum load resistance 550 Ω)
Measurement Range: Any setting in the range of 0 to 5 through 0 to 100 vol% O
2
(in 1 vol% O
2
), or partial range
Digital Communication (HART): 250 to 550 Ω, depending on number of eld devices connected
to the loop (multi-drop mode).
Note: HART is a registered trademark of the HART Communication Foundation.
Display Range: 0 to 100 vol% O
2
Warm-up Time: Approx. 20 min.
Repeatability: (Excluding the case where the reference gas is by natural convection)
±0.5% Maximum value of set range. (range from 0 to 5 vol% O
2
or more
and less than 0 to 25 vol% O
2
range)
±1% Maximum value of set range.
(range from 0 to 25 vol% O
2
or more and up to 0 to 100 vol% O
2
range)
Linearity: (Excluding standard gas tolerance)
(Excluding the case where the reference gas is by natural convection)
(Use oxygen of known concentration (within the measuring range) as the
zero and span calibration gases.)
