Outstanding long term stability under high humidity conditions
The operation principle of EE211 copes with the causes for poor long-term stability of non-heated
sensors at continuously high humidity. The constant over-temperature of the EE211 sensing head
(approx. 5 °C = 9 °F) means max. 76 % RH humidity at the sensors and enables following benefits:
• The sensing head of EE211 stays dry even under condensing conditions, which prevents dust and dirt
from sticking to the sensor and leads to outstanding long-term stability.
• The combination of dry sensing head, E+E proprietary coating of the sensing element and sealed
solder pads minimize the impact of corrosive agents.
• Maximum humidity of 76 % RH at the sensor eliminates the drift caused by exposure to continuous
high humidity.
