Hot-wire Calibration Systems (Hot-wire Calibrator)
The Dantec Dynamics Hot-Wire Calibrator is a simple, but accurate, device for 2-point calibration of most hot-wire probes used with Constant Temperature Anemometers. The calibrator produces a free jet, where the probe is placed during calibration. It requires a normal pressurized air supply and is able to set velocities from 0.5 m/s to 60 m/s.
It is primarily designed to provide two-point calibrations of standard wire probes, but can also be used for multi-point calibrations. By combining two sets of measured velocity-voltage values with a generic uni-curve transfer function it is possible to create a calibration function for an actual probe, which is valid for the entire velocity range.Kembali
