75 micron probe
0.075mm Interchangeable Probe
All dimensions are in mm. All probes are hand made and as such there is always some variation between individual devices. Please contact us if the actual dimensions are critical to your work.
The 0.075mm needle hydrophone has a good signal-to-noise ratio and Precision Acoustics would recommend the use of this device in high frequency, high pressure fields to minimise the effect of spatial averaging.
|Output Impedance: ||14pF+/- 2pF |
|Typical Probe Sensitivity: ||10nV/Pa (equivalent to -280.2dB re 1V/uPa) at 3MHz when measured at the output of a correctly terminated HP1 Submersible Preamplifier |
|Sensitivity Tolerance: ||Sensitivity variation between individual probes is approximately +/-3dB |
|Typical Frequency Response:||Flat (+/-2dB): 2 to 15MHz|
Flat (+/-4dB): 1 to >30MHz
|Sensor Material: ||9 micron thick gold electroded Polyvinylidene fluoride (PVdF) film |
|Sensor Dimension: ||0.075mm diameter disc |
