Apparatus for measuring the oxygen concentration in a gas using an inhomogeneous magnetic field

摘要

Measuring device comprises two units (5) with a gap (11) for producing a magnetic field; and a sensor (2) held in the gap which can be tilted from its resting position depending on the oxygen concentration. A frame (3) for receiving and holding the sensor is provided in the gap. Preferred Features: The sensor has two hollow sturdy rectangular bodies (2A, 2B) connected together using a bar-like element (2S) which is fixed within the frame via a spring element (4). The spring element is made from silicon. A conducting pathway (6) is formed on the surface of the sensor.
