Matching of various sensor protection applications in automobiles

Automotive sensors must be able to accurately and reliably measure and monitor critical system data to ensure fuel economy and safety. However, high temperatures and humidity can cause differential pressure, resulting in overpressure or vacuum conditions inside the sensor. These can lead to missed readings or directly lead to sensor failure, which can lead to automotive components or entire systems.

Renault Ruinuo waterproof and breathable products have a unique structure that quickly balances instantaneous or extreme pressure differences.

●Provide excellent airflow control/avoid failures caused by condensation; Overpressure or vacuum state;

● Effective shielding of liquids/prevention of water, automotive solvents or oil ingress;

● Reliable contaminant/separating dust, dirt and debris;

In order to withstand operating temperatures in excess of 250°C, oxygen sensors require extremely efficient waterproof and breathable products that quickly equilibrate pressure through high airflow. At the same time, the waterproof and breathable product must effectively protect the sensor from contamination by water, dust and other particles.

How well a humidity sensor performs depends on its breathability. The high airflow and water vapor transmission rate allows the sensor to respond quickly to changes in the surrounding environment. The ability to quickly balance pressure plays an important role in maintaining accurate readings and preventing failures in sensors and even component systems.

Because they are installed near hot engines, the sensors are subject to extreme temperature changes, corrosive vapors and liquids under the hood. Any effect can lead to incorrect readings or sensor failure, and consequently component or system failure. Automotive waterproof and breathable products quickly balance pressure, allowing position sensors and drives to consistently deliver accurate readings.

Radar sensors are met with a variety of tough tests in real road environments. Especially when installed on the front bead or near the bumper, they must be able to withstand extreme weather such as ice, rain and heat waves, and must not be affected by road obstacles such as puddles, gravel, oil, mud, etc.
