Thermal Anemometry Grid Sensor

Arlit, M.; Schleicher, E.; Hampel, U.

A novel thermal anemometry grid sensor was developed for the simultaneous measurement of cross-sectional temperature and axial velocity distribution in a fluid flow. The sensor consists of a set of temperature resistors arranged in a regular grid. Each temperature resistor allows the simultaneous measurement of fluid temperature via electrical resistance and of flow velocity via constant voltage thermal anemometry. Cross-sectional measurement is enabled by applying a special multiplexing-excitation scheme. In this paper we report on the design and characterization of a prototypical sensor.
