テキストボックス: Model IHW-100 テキストボックス: Intelligent Hot-Wire Anemometer

テキストボックス: Highly responsive 2-channel flow measurement.
Software-controlled probe calibration, measurement, analysis, and display.
Variety of probes to meet individual measuring needs.
Ideal solution for turbulent flow research and analysis.

FEATURES

Automatic probe resistance measurement and setup by the built-in CPU.
Simple operation by the software.
2-dimensional (2-channel) fluctuating flow measurement.
Up to 4 units connected for 8 channels.
Linearization and temperature compensation by the software.

テキストボックス: Principle of Hot-Wire Anemometry
When an airflow reduces the temperature of the hot wire sensor, the current passing through the sensor changes to generate heat and maintain equilibrium. The change is correlated to the air velocity. A hot-wire anemometer converts electric signals into air velocity readings.
