Features:
The built-in heater assembly of the probe can be
replaced on site, reducing maintenance costs.
The probe uses a long-life, high-reliability Zirconia
sensor.
The probe uses three-reference gas supply methods
(natural air convection, instrument air, and pressure
compensated) in its applications.
The separate type converter incorporates a LCD
touchscreen for ease of operation.
This converter can be used as an oxygen analyzer as
well as a high temperature humidity analyzer.
The integrated type integrates both probe and
converter, to reduce wiring, piping, and installation
costs. This type of unit uses an optical switch for
ease of operation at the site.
Remote maintenance using digital communications
(HART) reduces maintenance costs.
Description:
Oxygen Analyzer Measurement 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. Measurement System: Zirconia system Measurement Range: 0.01 to 100 vol% O2 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% O2 (in 1 vol% O2), or partial range Digital Communication (HART): 250 to 550 Ω, depending on number of field devices connected to the loop (multi-drop mode). Display Range: 0 to 100 vol% O2 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% O2 or more and less than 0 to 25 vol% O2 range ± 1% Maximum value of set range; range from 0 to 25 vol% O2 or more and up to 0 to 100 vol% O2 range Linearity: (Excluding standard gas tolerance) (Excluding the case where the reference gas is by natural convection) (Use oxygen of known concentration (with in the measuring range) as the zero and span calibration gases.) ± 1% Maximum value of set range; 0 to 5 vol% O2 or more and less than 0 to 25 vol% O2 range (Sample gas pressure: within ± 4.9 kPa) ± 3% Maximum value of set range; 0 to 25 vol% O2 or more and less than 0 to 50 vol% O2 range (Sample gas pressure: within ± 0.49 kPa) ± 5% Maximum value of set range; 0 to 50 vol% O2 or more and up to 0 to 100 vol% O2 range (Sample gas pressure: within ± 0.49 kPa) 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
