Our high-performance Needle Hydrophone System consists of a range of interchangeable PVdF needle hydrophone probes, a submersible wide-band amplifier and a DC coupler.
The needle probes are available in a range of diameters from 0.04mm to 4mm, with film thickness ranging from 9 µm to 28 µm. Custom versions of hydrophones are available, such as right angle or side facing versions. Please contact us to discuss any special requirements you have.
The L-shaped mount, pre-amp and DC coupler are included with all systems along with a calibration 1-30MHz (0.040mm, 0.075mm, 0.2mm, 0.5mm) & 1-30MHz (1mm, 2mm, 4mm).
Needle hydrophones are good general-purpose measuring devices. They are available in a wide range of diameters from 4.0 mm down to 0.04 mm. The frequency response of a needle hydrophone is dependent on the size of the active element of the hydrophone and the chart below provides an indication of the frequency range of these devices.
