This application note gives us info regarding technology, pressure, solid polymer, oxygen sensors, partial pressure sensors, anode, measuring oxygen, carrier, membrane, pressure sensors, controlled oxygen, and cathode. In the application note we can learn explanation around sensors, molecular weight, load, gas, sensor technology, concentration, galvanic oxygen sensors, temperature, ambient pressure, polymer membrane, control, and sensor.
Lots of info related to response time, flow, sensor output, oxygen, alphasense oxygen sensors, mass flow control, output, oxygen sensor, mass flow, diffusion, output current, and electrolyte are explained inside this application note. Here are excerpted from the application note:
Alphasense Application Note AAN 009 AAN009 HOW OXYGEN SENSORS WORK Galvanic oxygen sensors are the most popular technology for measuring oxygen concentration in air. These oxygen sensors can be divided into two types: • • Mass flow control using capillary Partial pressure control using solid polymer membrane Oxygen Sensor Chemistry Alphasense oxygen sensors operate like a metal/air battery. Since oxygen is reduced at the cathode, the partial pressure on the cathodic side of the membrane is virtually zero, giving a driving force which is linearly dependent on oxygen partial pressure, so the rate of gas diffusion (and hence sensor output) is linearly dependent on the oxygen partial pressure.
Giving more content, this application note explains discussion around lead oxidation, mass flow sensors, pressure step, oxygen concentration, pressure dependence, current, rate, voltage, partial pressure, flow control, response, and diffusivity.
