Use caution:
1 Conditions that must be avoided
1.1 Exposure to silicone vapors
If the surface of the sensor absorbs silicone vapors, the sensor's sensitive material will be trapped, suppressing the sensor's
Sensitive and unrecoverable. Sensors should be protected from exposure to silicone adhesives, hair gel, silicone rubber, putty or
It contains where silicone additives may be present.
1.2 Highly corrosive environment
sensors exposed to high concentrations of corrosive gases (such as H2S, SOX, Cl2, HCl, etc.) not only cause corrosion or damage to the heating material and sensor leads, but also cause irreversible performance of sensitive materials change.
1.3 Alkali, alkali metal salts, halogen pollution
Sensors that are contaminated with alkaline metals, especially brines, and exposed to halogens, such as fluorine, can also cause performance deterioration.
1.4 Contact with water splashed in water or immersed in water can cause a decrease in sensitive properties.
1.5 Icing
The freezing of water on the surface of the sensitive element can cause the sensitive material to fragment and lose its sensitive properties.
1.6 The applied voltage is too high
If the voltage applied to the sensing element or heater is higher than the specified value, even if the sensor is not physically damaged or destroyed, the lead wire and/or heater may be damaged and the sensitivity characteristics of the sensor may be degraded.
