Device for regulating a wire anemometer

摘要

An anemometer probe having a single wire or n wires (n>1) that are mutually parallel, for a measurement close to a wall, comprising, for each wire: a) two pins for holding the wire in place, the end of each pin having a flat zone for positioning and fastening the wire; and b) a straight portion of wire brazed onto said flat zones for positioning and fastening the wire.

主权项

1. A thermo-anemometer, comprising:
means for supplying and means for regulating a supply current at a constant level to a wire of a wire anemometer and a reference resistor, means for establishing a difference between a signal at the terminals of the wire and a signal at the terminals of the reference resistor, and means for maintaining a constant temperature of the reference resistor and the wire; wherein said means for regulating a supply current comprises a diode-mounted regulating transistor and a potentiometer and is configured to regulate the supply current such that the wire anemometer operates in cold wire operation.
