The Micromodem can be configured to utilize nearly any transducer for a particular application. We test the transducers and design magnetic matching networks to optimize to acoustic source level and bandwidth for a given application. Below are several of the transducers, hydrophones and transducer towfish that we routinely utilize with Micromodem systems.
WH-BT-2 Double Ring 28 kHz Transducer Specification Sheet:
Standard omni-directional transducer used for our 25 kHz modem systems.
Produces ~6dB more acoustic source level (or equivalently a doubling in range) over the 211001 single ring tranducer.
211002-SPC details mechanical dimensions, and included hardware.
BTech BT28-UF Duoble Ring 28kHz Transducer with Feedtrough Specification Sheet:
Omni-direction transducer used with our 28 kHz modem systems that require no cables or connectors.
We have backing blocks available that allow for the addition of a connector to this transducer.
211002-UF-SPC details mechanical dimensions, and included hardware.
Benthos AT18-A1 15 kHz Transducer with Backing Blocks (LPMBH):
This is a directional transducer for our 15 kHz modem systems. We typcially use this transducer in vertical channels. We have backside baffles designs for this transducer that increase the front to back ratio receive response to improve performance in noisy environments.
213104-ASM details mechanical dimensions, and included hardware.
Benthos AT18-AT 15 kHz Transducer with Backing Blocks (LPMBH):
This is an omni-directional transducer for our 15 kHz modem systems.
213108-ASM details mechanical dimensions, and included hardware.
Geospectrum M27-930 10 kHz Transducer:
This is a hemisperical transducer for our 10 kHz modem systems.
GS M27-930 details mechanical dimensions, and included hardware.
4 Element HTI-96-MIN (CM) Spatial Diversity Array:
This 4 element spatial diversity array is used to increase the performance of our PSK data rates.
214002a-ASM details mechanical dimensions, and included hardware.
4 Element HTI-96-MIN (CM) Spatial Diversity Array Inline:
This 4 element spatial diversity array is used to increase the performance of our PSK data rates. Inline design is more robust.
214008a-ASM details mechanical dimensions, and included hardware.
Transducer Towfish for 211001 WH-BT-1 and 211002 WH-BT-2 Transducers:
This is our standard 25kHz transducer towfish. Pelican shipping case is included.
224001-ASM details mechanical dimensions, and included hardware.
Transducer Towfish for Benthos AT18-AT Transducer:
This is our standard 15kHz transducer towfish. Pelican shipping case is included.
224015-ASM details mechanical dimensions, and included hardware.
Transducer Towfish for GS M27-930 or ITC-3013 Transducer:
This is our standard 10kHz transducer towfish. Pelican shipping case is included.
224072-ASM details mechanical dimensions, and included hardware.
