Reliable measurement starts with the right protection

E+E protection concepts help sensors maintain stability, accuracy and reliability over the long term. They are used in applications where contamination, ageing, condensation or aggressive process conditions can affect sensor performance.

"What are protection concepts and how do they work?
Depending on the sensor type and application, protection can be applied to the sensing element, sensitive connection points or specific functional areas of the sensor. The aim is always the same: to protect measurement performance without compromising the requirements of the application.

Different applications expose sensors to very different risks. A moisture in oil sensor faces different conditions than a humidity sensor in a climate chamber, a fume hood or a drying process. E+E Elektronik therefore combines sensor expertise, application knowledge and its own technology development. This ensures the right protection level for each measurement task.

E+E protection concepts create dedicated barriers or protective layers on the parts of the sensor that are particularly exposed.

Depending on the concept, this can include:
• protective coatings on the sensing element
• barriers against chemical contamination
• protection of sensor leads and solder pads
• encapsulation of critical connection areas
• application specific combinations of multiple protection technologies

The protection concept is selected according to the expected stress factors. This gives the sensor the necessary level of protection while maintaining the measurement performance required by the process."
