Pemancar Sfera 30kHz-60kHz Pemancar Akustik Bawah Air Transduser Hidrofon
Kandungan pengukuran:
Kekonduksian dan Kemuatan Keluk
Ukur keluk kekonduksian dan kemuatan transduser.
Hantar Balasan Voltan
Ukur tindak balas voltan penghantaran dalam julat frekuensi 30Hz ~ 60kHz.
tahap sumber bunyi pelepasan
Tahap sumber bunyi pada 45kHz tidak kurang daripada 190dB.
Sensitiviti penerima
Ukur sensitiviti penerimaan dalam julat frekuensi 30Hz～60kHz, dan ia tidak boleh lebih rendah daripada -203dB pada 45kHz.
kearah mendatar
Omnidirectional, mengukur titik frekuensi 30kHz, 40kHz, 50kHz, 60kHz.
kearah menegak
Tidak kurang daripada 60°, kekerapan pengukuran ialah 30kHz, 40kHz, 50kHz, 60kHz.
Tekanan hidrostatik: 2MPa.
