The MKY30 is a receiving hydrophone used for low- and medium-frequency underwater acoustic measurements. Its internal sensitive element is made of high-performance piezoelectric ceramic material, and it is encapsulated with polyurethane on the outside. The probe of this hydrophone can integrate a preamplifier internally, featuring high sensitivity, low noise, and high resistance to hydrostatic pressure. The ceramic piezoelectric sensing element and its internal support structure are sealed in a sound-transmitting, lead-free, nitrile rubber housing. The support structure is made of a metal alloy, which has extremely strong corrosion resistance and very good anti-fouling performance when immersed in seawater.
