Heavy Duty variants with aeration and ventilation membrane
The aeration and ventilation membrane ensures an improved pressure equalization
and allows the exchange of air and heat between the sensor housing and the envi‐
ronment. The breathable membrane allows ambient air to either penetrate into the
device, or escape again depending on the prevailing ambient conditions. In particular
for applications with frequently changing environmental influences (e.g., large tempera‐
ture fluctuations or fast temperature changes) or with standing water, the membrane
ensures a reliable pressure equalization and thereby relieves the seals and adhesive
joints of the sensor housing. This can improve the expected service life of the device in
the application.
