More detail
Our high-performance needle hydrophone system consists of a range of interchangeable PVdF needle hydrophone probes, a submersible wide-band preamplifier and a DC coupler.
The needle probes are available in a range of diameters from 0.04 mm to 4 mm, 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 preamplifier and DC coupler are included with all systems along with a hydrophone calibration 1 MHz to 30 MHz (0.040 mm, 0.075 mm, 0.2 mm, 0.5 mm) & 1 MHz to 20 MHz (1.0 mm) in steps of 1 MHz, while our 2.0 mm and 4.0 mm needle hydrophones come with a 20 dB in-line attenuator and calibration from 0.3 MHz to 1 MHz in steps of 50 kHz.
Needle hydrophones
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.
