Velocity and directional calibration of hot-wire and hot-film probes
The first condition for high quality hot-wire or hot-film anemometry measurements is high precision calibration of the sensor.
The Standalone Calibration solution offers automated high accuracy velocity calibration of any hot-wire or hot-film sensor. Optionally even directional calibration is available.
The standalone velocity calibration functionality is achieved using a StreamLine Pro Automatic Calibrator, a Standalone Calibration Software module, an A/D converter and a system controller (Desktop PC or Laptop).
For the directional calibration of multiple-sensor probes, either the Automatic Directional Calibrator (ADC) or the manual Pitch/Yaw/Roll Manipulator can be used.
The A/D converter board must be in the list of supported devices in the Standalone Calibration Software, and National Instruments DAQmx device support is included as standard.

Measurement Principle
CTA is a measurement technique well suited for the study of fine structures in turbulent flows. The working principle is based on the cooling effect of a flow on a heated body.
