Sensor Technologies
Reliable measurement starts with the right protection
Industrial humidity and moisture in oil sensors are often exposed to more than just a clean environment. Dust, oil vapours, chemical contamination, ageing process media, cleaning residues, condensation, aggressive gases or polluted environments can influence the sensing element and critical connection points. This can lead to sensor drift, unstable readings, shorter service intervals, higher maintenance effort and less reliable process control.
Sensor protection is therefore more than an accessory. It is a key factor for stable measurement performance in industrial applications.
E+E Elektronik offers dedicated protection concepts for humidity and moisture in oil sensing elements and critical sensor components. The concept is selected according to the application, the medium and the operating conditions. It protects against environmental or chemical influences, supports stable measurement over the long term and can reduce maintenance requirements. E+E Elektronik does not use one standard protection concept for every application. The protection level must match the measurement task.

ChemShield – Protection Against Chemical Contamination
ChemShield Technology is a new barrier concept from E+E Elektronik for selected applications where chemical contamination can affect humidity or moisture in oil sensor performance. A protective layer is applied to defined areas such as the sensing element and soldering points. It acts as a barrier against harmful chemical influences and supports stable measurement in chemically demanding environments.
ChemShield is especially relevant where process media changes over time, where oils age or oxidise, or where chemical pollutants can cause drift effects at the sensing element. It extends the application range of selected E+E Elektronik humidity and moisture in oil sensors into environments that require enhanced protection against chemical contamination.
SensShield - Protective Sensing Element Coating
The SensShield is a protective layer applied to the humidity sensing elements, their leads and soldering points. It protects the sensitive measurement area against application-related influences and supports maintain stable sensor performance in demanding environments.
SensShield is especially relevant where sensing elements are exposed to dust, dirt, oil-based contamination, salts, moisture exposure or corrosion related stress. The SensShield coating helps prevent stray impedances caused by deposits on the active sensor surface and on the connecting leads. This improves stability over the long term and can reduce maintenance requirements.
LeadsShield – Protective Sensor Leads Encapsulation
LeadsShield Technology protects sensitive connection points such as sensor leads and soldering areas against application related stress. The protective encapsulation encloses the connection leads and soldering points. This helps prevent corrosion and contamination. Only the humidity or moisture in oil sensing element is exposed to the medium to be measured.
By protecting these connection points, LeadsShield increases the robustness of the sensor design without changing the sensing element itself. This is important when fast sensor response must be preserved.
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 different risks. A moisture in oil sensor faces other 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 around the parts of the sensor that are most exposed to environmental or chemical stress. Depending on the concept, this can include:
- protective coatings on the sensing element
- chemical barrier layers against harmful contamination
- protection of sensor leads and soldering points
- encapsulation of critical connection areas
- application specific combinations of 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.
Advantages of E+E Shield Technologies
E+E Shield Technologies support reliable humidity and moisture in oil measurements where contamination, ageing, chemical load or aggressive environments can affect sensor performance. They help maintain stable reading over time and reduce the risk of measurement drift.
Different applications create different risks for sensors. E+E Elektronik offers dedicated protection concepts for specific measurement tasks, media and operating conditions. This gives the sensor the required level of protection without unnecessary complexity.
Protection must match the measurement task. In applications where fast response is important, E+E Elektronik avoids unnecessary protection measures that would slow down the sensor. This helps balance protection, response time and serviceability.
E+E Elektronik protects the parts of the humidity and moisture in oil sensors that are most exposed to application related stress. These can include the sensing element, sensor leads, soldering points or other critical connection areas. The result is a robust sensor concept for real operating conditions.
E+E protection concepts help reduce maintenance effort and extend the usability of sensors in demanding industrial applications.
