Product details

Product introduction

The HTD-93 hydrophone adopts IEPE technology and supports 4mA or 10mA constant current output. The hydrophone is equipped with a cylindrical piezoelectric ceramic with a sensitivity of -208dB. It supports obtaining gains of 10, 20, 30, 40, 50, and 60dB by adjusting the amplification factor of the preamplifier, and can provide horizontal omnidirectional response in the frequency range of 2Hz~84kHz. The hydrophone can be equipped with threads for fixing on pipelines.

Main application scenarios

(1) Passive acoustic monitoring;

(2) Measurement of target radiated noise;

(3) Connect the 4-20mA current circuit to the industrial control system;

(4) Urban pipeline leakage detection.
