An atmosphere continuing combustible gases such as methane, alcohol, hydrogen and
carbon monoxide may cause errors in measurement.
(3) Silicon gases
Never use silicon gases containing siloxane, as these gases react with the sensor and
produce oxides, destroying the performance of the sensor over a very short period.
(4) Fluorocarbons
Do not use freons and others that contain halogens (F, Cl and Br), as these gasses
react with materials inside the sensor and damage the performance.
(5) Sulfur oxides and hydrogen
Never use sulfur oxides (SOx) and hydrogen (H
2
), as they react with the sensor and
destroy the performance of the sensor over a very short period.
3.2 Operating conditions
(1) Dust and oil mist
Employ a filter system to eliminate dust and oil mists that clog the sensor and
analyzer filter, resulting in problems, measurement errors and incorrect responses.
(2) Water and condensation moisture
Contact of the sensor with water may destroy the sensor. Exclude water from the
system.
3.3 Others
(1)

(3)
Do not touch the sensor mesh while in operation, since the sensor mesh is heated to 50
- 80°C.
Do not subject the sensor to a shock of 10G or greater which may cause breaks in the
wiring and cracks in the sensor chip.
The sensor element is made of a ceramic material. Never expose it to heat suddenly
as this could destroy the element.
4. Others
Any product described in the catalogues may be altered without prior notice to improve
reliability, function or design. Fujikura is not responsible for any incidents due to
application of products and circuits described in the catalogues. No Fujikura patents or

Since the sensor element
functions at 450°C, gases that ignite below that temperature must not be used.
