3.5 Influence of vibrations, impacts
Strong vibrations and impacts may cause damage of the sensor.
4 Factors shortening the lifetime of the sensor
There are many factors that shorten the life of the Hot-wire sensor:
silicone vapors absorb themselves on the surface of the sensor, gradually decreasing its sensitivity
(avoid exposure of the sensor to silicone adhesives, silicone latexes, raising agents, oils, greases),
high concentrations of corrosive gases (mainly NH
3
, H
2
S, SO
2
, HCl),
exposure to alkali metals, brine and halogens (mainly fluorine),
presence of concentrations well beyond the measuring range,
supply voltage higher than declared in the technical specification of the sensor,
very dirty atmosphere or with constantly high humidity,
ambient temperature beyond range of the environmental parameters of the sensor.
