Si<br />
Long tube -indicates that the unit is longer<br />

Housing material<br />
As described above, <strong>and</strong> the transducer is<br />
mounted at an angle of 90_ perpendicular<br />
to the longitudinal axes of the transponder<br />
Aluminium is st<strong>and</strong>ard housing material. If Stainless steel is<br />
used, the abbreviation “St” is added to the transponder name<br />
(see example below).<br />
Example: <strong>MPT</strong> 319/DT-St<br />
The example given (<strong>MPT</strong> 319/DT-St) therefore indicates that<br />
the transponder unit is an Multifunction Positioning<br />
Transponder, operating in the 30 kHz b<strong>and</strong>, rated to 1000 meters<br />
depth, with a ± 90º beam width, <strong>and</strong> including the Depth <strong>and</strong><br />
Temperature sensors. The housing material is stainless steel.<br />

Basic models<br />
<strong>SPT</strong> 314<br />
The <strong>SPT</strong> 314 can only operate as an SSBL transponder to<br />
provide positional information. It is equipped with a ± 45º<br />
beamwidth transducer. All <strong>SPT</strong> 314 models are based on this<br />
basic model.<br />
<strong>SPT</strong> 319<br />
The <strong>SPT</strong> 319 can only operate as an SSBL transponder to<br />
provide positional information. It is equipped with a ± 90º<br />
beamwidth transducer. All <strong>SPT</strong> 319 models are based on this<br />
basic model.<br />
