Abstract
A temperature probe has a sensor housing with a sensor head and an associated scoop, together forming a primary airflow path, with the sensor head containing a sample chamber for the thermal sensor. Gaseous fluid is caused to pass through the primary airflow path, where its pressure is increased. The sample chamber is adjacent to the primary airflow path and configured to draw a sample of the flowing gaseous fluid out of the primary airflow path and bring it to and through the sampling chamber, while maintaining the sampled flow at essentially the same immersion depth as the primary airflow path. The sensor is connected to the housing and extends into the sampling chamber so that the gaseous fluid flows across the sensor's axis and sensing surface, rather than along the sensor's longitudinal axis.
