1-5 Installation environment
(1) Ambient temperature : -20°C to +55°C (receiver unit and transmitter unit)
-5°C to +45°C (control unit)
(2) Ambient humidity :
≤
90% RH
(3) Optical path length (stack
inner diameter) : 0.5 m to 5 m
* Consult us if the distance between the transmitter unit and the re-
ceiver unit is beyond 5 m.
(4) Standard flange : JIS10K 50A flange (JIS B 2212)
(5) Purge gas : Instrument air
(If not available, a compressor is required. The air shall contain
neither oil nor mist.)
Use N2 if the target gas contains explosive gas or combustible gas,
and for O2 analyzers other than the instrument air purge version.
(6) Purge gas fl ow rate :
≥
20 L/min (depending on measured gas velocity)
(7) Measured gas condition : Temperature: as specified in “1-1 (4) Measurable component and
range” of APPENDIX 1.
Pressure: ±10kPa
Moisture: 50vol% or less (or should not be saturated water vapor)
Velocity: 25m/s or less (However, consultation is necessary for the
environment where dust (1g/Nm
3
or more) or water (25vol% or
more) exists.) (Prevention of dust deposition or dew condensation
due to increase in air purge flow rate is required)
(8) Dust (when the optical
path length is 1 m): : Standard version:
≤
5 g/m3 (N)
Dust resistant version: O2 measurement:
≤
10 g/m3 (N)
Low level CO:
≤
20 g/m3 (N)
Others:
≤
15 g/m3 (N)
(9) Vibration : 0.5G or less (0.2G or less when the frequency range is 20 to 40Hz)
(When the optical path length is 1m.)
(10) Mounting angle : Horizontally ±5 degree or less (No dew condensation should accu-
mulate on the window.)
(11) Light axis fluctuation
range
: Within 0.3 degree (When the path length is 0.5m)
1-6 Performance
(1) Repeatability : ±1.0% FS (depending on measurable component and range)
*CO+O
2
: ±2.0%FS
(2) Linearity : ±1.0% FS (depending on measurable component and range)
*CO+O2: ±3.0%FS
(3) Zero drift : ±2.0%FS / 6 months (depending on measurable component and
range)
*CO+O2: ±4.0%FS
(4) Span drift : ±3.0%FS / 6 months (depending on measurable component and
range)
*CO+O2: ±4.0%FS
(5) Interference from other
gas components
: ±2.0%FS
(6) Minimum detectable limit : 1% of the minimum range
(7) Response time (90% FS
response)
: 1 to 2 seconds
*CO+O2:1 to 4 seconds
(8) Warm up time : 90 minutes or less
