Note: Quantity in this is number of accessories supplied as standard. For instance, two K9218SE parts, i.e.,
two slide rails, are supplied as standard. When ordering separately, the required number of should be considered.
Dedicated Zirconia O
2
Sensor (to be purchased separately)
For O
2
correction, the IR400 can accept linearized 0 to 1 V DC signal coming from an analyzer
calibrated to 0 to 25%O
2
of full scale. Dedicated zirconia O
2
sensor , Model ZX8D, is available from
Yokogawa.
Measuring method: Zirconia system Measurable component and measuring range:
Measurable component Minimum range Maximum range
Oxygen (O
2
) 0-5 vol% 0-25 vol%
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)
Measured gas flow rate: 0.5 ± 0.25 L / min
Remark:
The Zirconia system, due to its principle, may produce a measuring error
due to relative concentration versus the combustible O
2
gas concentration.
Also, a corrosive gas (SO
2
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:
Installation altitude: 2000 m or less
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.
Safety: EN61010-1
EMC: EN61326-1 Class A, (For use in industrial locations),
EN61326-2-3, EN61000-3-2, EN61000-3-3
EMC Regulatory Arrangement in Australia and New Zealand
Note: The product mounted in a steel enclosure conforms to the requirements of EMC directive.
