Product details

Product introduction

HTD-90 pipeline monitoring hydrophone features a cylindrical piezoelectric ceramic and supports gains of 10, 20, 30, 40, 50, and 60 dB by adjusting the preamplifier's amplification factor. It provides a horizontal omnidirectional response within the 2Hz~84kHz frequency band. According to the different thread specifications selected for the hydrophone, it is divided into HTD-90 type I (M36x2, 25mm thread) and HTD-90 type II (M36x2, 14mm thread). The product can operate normally after undergoing 7*24h pressure testing at over 10MPa (i.e., supporting a maximum working depth of 1000 meters).

Main application scenarios

(1) Passive acoustic monitoring;

(2) Measurement of target radiated noise;

(3) Pipeline noise measurement, etc.
