Oxygen Sensors
AMETEK SFMS oxygen sensors provide accurate oxygen concentration measurement for aircraft fuel tank inerting systems. Utilizing heated zirconia sensing technology and integrated signal processing, they deliver fast response, reliable performance, and built-in diagnostic capability for critical aerospace applications.

Product Details
AMETEK Sensors & Fluid Management Systems (SFMS) designs and manufactures aMETEK oxygen sensors measure oxygen concentration in aircraft inerting gas ducting using a heated zirconia ceramic element with platinum coatings and dedicated signal processing. The sensing element reaches operating temperature quickly and provides an electrical output proportional to oxygen concentration.
