FSI - Model HMS-622 12KM - Hull Mounted Seismic Profiler - Brochure

Deep water sub-bottom profiling applications (1Km to 12Km) require an array of 4 to 36 low frequency transducers installed in a hull-mounted sea chest. The HMS-12KM system with the HMS-622 CHIRPceiverTM and hull mounted transducer arrays fills this range of survey requirements. The frequency bands supported by the HMS- 12KM include LF (1KHz-10KHz) and HF (8KHz-23KHz) with a standard 2 channel transceiver. CW frequencies can also be programmed within the respective band. The transducer arrays are configured to perform both the transmit and the receive functions of the system. The transducers are wired to a junction box containing the SCP-10KM Software Controlled Preamplifier which is collocated with the sea chest and is permanently connected through a shipboard cable to a topside junction box which provides the interface to the HMS-622 CHIRPceiver and workstation.
