Instruction Manual

9 - 12 IM 11G02M01-01E
Dedicated Zirconia O2 Sensor (to be purchased
separately)
For O
2 correction, the IR200 can accept linealized 0 to 1 V
DC signal coming from an analyzer calibrated to 0 to 25%
O
2 of full scale. Dedicated zirconia O2 sensor, Model
ZX8D, is available from Yokogawa.
Measuring method: Zirconia system
Measurable component and measuring range:
Measurable component Minimum range Maximum range
025 vol% 0225 vol%
T12.EPS
Oxygen (O 2 )
Repeatability: Within ±0.5% of full scale
Linearity: Within ±1% of full scale
Zero drift: Within ±1% of full scale/week
Span drift: Within ±2% of full scale/week
Response time: Approx. 20 seconds (for 90% response)
Sample gas flow rate: 0.5 ±0.25 L/min
Note: The Zirconia system, due to its principle, may
produce a measuring error depending on the
relative concentration versus the combustible O
2
gas concentration. Also, a corrosive gas (SO2 of
250 ppm or more, etc.) may affect the life of the
sensor
Gas inlet/outlet size: Rc1/4
Power supply: 90 to 126 V AC or 200 to 240 V AC,
50/60 Hz
Enclosure: Steel casing, for indoor application
Indication: Temperature indication (LED)
Temperature alarm output:
Contact output 1a contact,
Contact capacity 220 V AC, 1 A (resistive
load)
Safety and EMC conforming standards:
Safety: EN61010-1
Pollution degree 2 (Note)
Installation category II (Note)
Note: Installation category, called over-
voltage category, specifies impulse
withstanding voltage. Category II is for
electrical equipment.
Pollution degree indicates the degree
of existence of solid, liquid, gas or other
inclusions which may reduce dielectric
strength. Degree 2 is the normal indoor
environment.
EMC: EN61326
