Product details

Product introduction

The HTD-90 pipeline monitoring dedicated hydrophone is equipped with cylindrical piezoelectric ceramics, which support 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. According to the different thread specifications of the hydrophone, it is divided into HTD-90 Type I (M36x2 25mm long thread) and HTD-90 Type II (M36x2 14mm long thread). After 7 * 24h and pressure testing above 10MPa, the product can work normally (i.e. support 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.
