Thermal Anemometry Systems

Product Details

There are many different types of sensors, wire or film, for 1D, 2D, and 3D velocity components, and for gaseous and liquid flows. The thermal anemometry system is an excellent tool for turbulent flow because of its high frequency response to measure the fluctuation of the flow and many versions of sensors used in different flow environments.   

A typical Thermal Anemometry system is made up of the following components:

• IFA 300 Constant Temperature Anemometer
• Multichannel digitizer
• ThermalPro Data Acquisition and Analysis software
• Hot Wire/Hot film sensor(s)

IFA-300 Constant Temperature Anemometer

The IFA-300 Constant Temperature Anemometer (CTA) is a state-of-the-art research anemometer capable of meeting the most demanding measurement requirements. It represents the depth of design capability and an understanding of the dynamics of constant temperature anemometry which TSI has developed over the past fifty years of building exceptional anemometry products. The anemometer, along with the ThermalPro Data Acquisition and Analysis software provides automatic tuning of the sensor(s) to provide accurate measurements of high speed flows (gas or liquid) and measurement of very low turbulence intensities, for your applications.

The IFA-300 unit comes with a single CTA channel, when multiple channels are needed, additional CTA can be purchased (up to 8 channels of CTA). If more than 8 channels are required for your flow research, an IFA-300 auxiliary cabinet is also required. This allows a total of 16 channels to be configured.

ThermalPro Data Acquisition and Analysis Software

The IFA 300 is designed for complete computer control through the ThermalPro software. System operating functions, such as control of the overheat ratios and signal conditioner settings, are handled via an RS-232 interface, while the high speed analog data from the anemometer output is managed with a high speed multichannel digitizer installed inside the computer. The ThermalPro software is supplied with the IFA 300 system to allow all control and data acquisition, data analysis and presentation of results.
