GeoAcoustics GeoPulse Pinger
GeoAcoustics GeoPulse adalah sistem profil sub-dasar yang digunakan untuk menentukan struktur bawah laut dengan menggunakan pantulan dari sinyal akustik berdaya tinggi yang dikirimkan dari platform di atas kapal, ditow atau dipasang pada bodi kapal. Sistem ini memiliki keandalan, daya tahan, kemudahan pengoperasian, dan fleksibilitas yang tinggi.
Kelengkapan
Spesifikasi
Transmitter 5430A
Input Power: 115/230 VAC ±10%, 47 – 63 Hz, 220 W maximum
Output Power: 10 KW with 0.75% duty cycle, continuously adjustable
Auxiliary Power: IEC Connector, unfused, 6A maximum
