Lubell VC2C Underwater Acoustic Transducer
The Lubell Labs VC2C is an underwater acoustic
transducer covering the frequency range of 50 Hz to 1500 Hz at
a maximum sound pressure level of 174dB/uPa/m @ 115 Hz. The
VC2C must be accurately pressurized while topside, in order to
balance the internal pressure with the external pressure for
the intended fixed operating depth. We recommend
connecting the VC2C to the 4 ohm and common terminals of the
InterM A-120 amplifier (North America sales only), which must
be purchased separately. Since the VC2C has a maximum current
rating of 2.5A, we recommend installing an inline fuse holder
with 2.5A fast-blow fuse in series with the white signal lead
to help protect the VC2C against burn-out. Sales of the VC2C
is limited to marine scientists and laboratories, ocean
engineers, and the military.
