Component Overview

A turbine wheel air flow sensor is a sensing component associated with the air-cycle machine that monitors airflow or related conditions at the cooling turbine to support control and protection of the refrigeration pack. By providing feedback on flow through the turbine stage, it helps the control system manage cooling performance and guard against off-design operation. Its primary function is reliable flow-related sensing in the hot, high-velocity air-cycle environment. Operating amid vibration, thermal cycling, and high airflow, it is subject to sensing-element drift, contamination or erosion of the sensing area, lead and connector fatigue, moisture ingress and corrosion, and mechanical or seal damage that degrade signal accuracy and stability. Repair and overhaul verify the sensing element and electrical integrity, clean or restore the sensing surface, and confirm calibrated output and response.
