Product introduction

The HTD-93 hydrophone utilizes IEPE technology and can function under a constant current output of either 4 mA or 10 mA. It is equipped with a cylindrical piezoelectric ceramic with a sensitivity of -208 dB. By adjusting the amplification factor of the preamplifier, gains of 10 dB, 20 dB, 30 dB, 40 dB, 50 dB, and 60 dB can be achieved. It offers a horizontal omnidirectional response within the frequency range of 2 Hz to 84 kHz. Optionally, threads can be chosen for fixing the hydrophone on pipes.

Main application scenarios

(1) Passive acoustic monitoring;

(2) Measurement of target radiated noise;

(3) Connection to the 4 - 20 mA current loop of the industrial control system.
