2. Specifications
Measuring system: Zirconia solid electrolyte
Measuring system:
Zirconia solid electrolyte
Measuring range:
Minimum range 0 to 5 vol% O
2
and maximum range of 0 to 25
vol% O
2
, if used in combination with infrared gas analyzer
Measurable component:
Oxygen in noncombustible gas or combustion exhaust gas
(sensor will be burned and error will appear if combustible gas is
mixed in sample gas)
Output signal:
4 to 20mA DC and 0 to 1V DC linear connected to infrared gas
analyzer or direct output from sensor of the ZX8D.
Sensor output:
Logical output of zirconia sensor (with sensor temperature of 800°C)
E = 50.74 log 20.6
X – B
E: Logical output (mV)
X: Measured gas concentration (%O
2
)
B: Blank voltage (mV)
Temperature alarm output:
Contact output normally-closed contact,
Contact capacity: 220V AC, 1A (resistive load)
Flow rate:
0.5±0.25 liter/minute (when connected with infrared gas analyzer)
NOTE :
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.
