Airmar TRIDUCER
rate a revolutionary self-closing valve to min­imize water flow into the boat when the
paddlewheel insert is removed. “Gushers” are
eliminated with this simple to maintain valve.

Fins provide on either side of the paddlewheel
for more accurate speed measurement in
cross-flow conditions.

Combined with our fairing, installation is
made simple. Made of urethane, the fairing
will never swell or rot, and the unique cutting
guide allows safer, more accurate cutting with
a band saw. High speed fairings are provided
with a corrosion resistant bolt to secure the
fairing and prevent rotation.

popular 50/200 kHz model

SS544 includes a streamlined fairing and is designed specifically for isolated

mounting to steel and aluminum hulls. It accommodates ceramics up to 44 mm
(1.75

New streamlined fairings for B744V, B744VL, and SS544V provide much impr oved

echosounding at speeds above 20 knots and greatly reduce drag

Versatile B66V and long stem B66VL mounts frequencies varying from 50 kHz to

Single Connector/

Dual Connector Systems

The piezoceramic element, speed, and temperature cir­cuitry are all within the bronze housing. The removable
paddlewheel insert contains no circuitry. The magnetic
field sensor to measure speed is mounted in the housing in
close proximity to the rotating paddlewheel. A single con­nector system is generally used when depth, speed, and
temperature will be processed in a single instrument or
when two instruments are within 1m (40") of each other.
When depth and speed/temperature functions will be pro­cessed in separate instruments, our cable can be split and
two connectors can be applied.

All signals are transmitted via a multi-conductor cable
with a high quality thermoplastic rubber jacket for
improved resistance to cutting, pinching, and degradation
from petroleum distillates. C144 cable is used in single
element TRIDUCER multisensors. Dual element multi­sensors use C145 cable.

Speed

The TRIDUCER multisensor provides accurate speed measurement
over the widest boat speed range of any thru-hull paddlewheel
transducer.

The combination of a hydrodynamic paddlewheel and paddlewheel ca v­ity, housing and fairing projection through the boundary layer and fins
on either side of the paddlewheel gives an unmatched linearity.

Temperature

Various temperature sensing devices can be
incorporated in the housing including ther­mistor and semiconductor types. See the
“Temperature” section for more detailed
information including thermal time constants.

Shielding

Inside the TRIDUCER multisensor housing,
shielding is used to eliminate interference
between the speed and depth sensors. A
shielded cable and separately shielded speed
and temperature conductors are used to pre­vent mutual interference. The bronze housing
also functions as a shield. Refer to wiring dia­gram beginning on p 35 for shielding details.
