WebMathematically speaking, the TAT of a flow is the sum of the Static Air Temperature (SAT) and a kinetic component (air compression and friction) depending on the speed and type of medium. Air compression and friction lead to a relative temperature increase compared to the Static Air Temperature (SAT) at altitude. WebAug 30, 2024 · The dissolved oxygen probe works by measuring the amount of oxygen that diffuses through the membrane into the sensor. Once oxygen enters the sensor, a chemical reduction reaction occurs, producing an electrical signal. The signal is read by the DO probe and displayed on the meter.
