Description

Unlike our conventional probes, these probes have pressure-sensors embedded in the body of the instrument to eliminate the attenuation of the high-frequency part of the signal, common to all external sensor probes. In addition, the probe is acoustically calibrated to correct even for the miniscule attenuation caused by the short internal tubing. These probes have a frequency response of 3.0 kHz or greater. They retain the <0.8% velocity measuring accuracy of the standard probes as well as the maximum incidence angle of 70° for seven-hole probes.
