2.2.1 Magnetometer
Fish
The Magnetometer Fish is a nose tow body meaning that it is supported underwater from a tow
point at the front of the fish. The sensor, with its permanently installed sensor fluid, is contained
in tough molded plastic surrounded the four fins. The sensor may be replaced if it is damaged,
but this is unlikely as the potting material is extremely strong. The electronics module is internal
to the fish body. . This module produces the polarize signal to the sensor, reads the precession
frequency and converts it to RS-232 for transmission up the tow cable. The tow cable is attached
to the fish using the third assembly, the Clevis tow point as shown.
There is a water-tight 8 pin Subconn marine connector inside the fish and which attaches to a
mating connector on the tow cable. The tow cable contains a clevis assembly that inserts in the
nose and is fastened with a clevis pin secure towing.
