MS® PTFE Venting Membrane Applied in Electrical Sensors Description

Keep Your Electrical Sensors Accurate

In the electronics industry, the protective vents of Membrane Solutions are mainly used in sensors.Our protective vents allow air to pass through and prevent solid contaminants, water and liquids from entering into the sensors, which ensure sensors not to be contaminated and ensure the sensitivity of the sensors. Meanwhile, Membrane Solutions’ protective vents can equalize the pressure drop changes inside and outside the enclosure due to the temperature changes with the good air permeability to extend the service life of sensors.

Features & Benefits

  • Protect the sensor from the pollutants, such as water, salt and other corrosive liquid, to ensure that the accuracy of sensor  
  • High air flow rates-to ensure adequate venting, pressure equalization and reduce the stress on the sealing strip
  • Simple installation.

Typical Applications

  • Tilt angle sensors
  • Accelerometer sensors
  • Humidity sensors
  • Chemical sensors 
  • Position sensors
  • Temperature transmitters
  • Magnetoresistive sensors
  • Angular transducers
