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 (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:
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.
