0.5mm probe

HP 0.5mm Interchangeable Probe - Order Code HPM05/3


All dimensions 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.

Description
Hydrophones of 0.5mm have been widely used in the measurement of high frequency ultrasound. With the exceptional signal-to-noise ratios obtainable from the HP series of probes, Precision Acoustics would recommend the use of this device for measurements where signal amplitudes are expected to be particularly low.

Specification

Output Impedance:
18pF+/- 3pF
Typical Probe Sensitivity:
300nV/Pa at 3MHz (equivalent to -250.5dB re 1V/uPa) 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): 3 to 15MHz
Flat (+/-4dB): 1 to 15MHz
Sensor Material:
9 micron thick gold electroded Polyvinylidene fluoride (PVdF) film
Sensor Dimension:
0.5mm diameter disc
