2.1 General Specifications
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 and chlorine.)
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

Output Signal: 4 to 20 mA DC (maximum load resistance 550
⍀)
Measurement Range: Any setting in the range of 0 to 5 through 0 to 100 vol% O
2
(in
1 vol% O

), or partial range
Digital Communication (HART): 250 to 550
⍀, depending on number of field devices
connected to the loop (multi-drop mode).

Response Time : Response of 90% within 5 seconds. (Measured from when gas is
introduced from calibration gas inlet and analog output start
changing.)
