Wide-range Low-noise Hydrophone with Preamplifier for Ultrasonic Measurements

Wide-range Low-noise Hydrophone with Preamplifier for Ultrasonic Measurements

Specification :

Type PH8106 is a wide-range, piezoelectric hydrophone with preamplifier for making absolute sound measurements over the frequency range 7Hz to 80 kHz, featuring an impressive receiving sensitivity of −173dB re 1V/μPa.

Built-in Preamplifier

A high-quality, thick-film, low-noise, 10 dB built-in preamplifier provides signal conditioning for transmission over long underwater cables. The preamplifier features a 7 Hz high-pass filter and an insert-voltage calibration facility, but does not allow the hydrophone to be used as a projector.

Uses

Measurement of weak, underwater signals

Features

Frequency range: 3 Hz to 80 kHz

Receiving sensitivity: –173dB re 1 V/μPa

Durable construction

Equivalent noise level well below sea-state zero
