Trisonondă Analogică DST800

The Raymarine DST800 analog triducer is a multifunction sensor designed to measure and transmit three essential navigation data types: depth, speed through water, and water temperature. It stands out for its analog operation, meaning it outputs raw signals that require a compatible instrument or converter to be interpreted and displayed.

This triducer performs three main functions:

Depth: It measures the distance between the sensor and the seabed.Speed: It measures the boat's speed through the water using a paddlewheel.Temperature: It measures the surrounding water temperature.

The depth sounder of the analog DST800 triducer typically operates at a frequency of 200 kHz. This frequency is common for depth detection applications on recreational boats.

The DST800 triducer can measure depth up to approximately 100 to 180 meters (330 to 600 feet), depending on water conditions and the quality of the display or converter used.

The DST800 analog triducer can measure boat speed through water in a range from 0 to approximately 45 knots.

The integrated temperature sensor in the DST800 triducer can measure water temperature in a range from -10°C to 40°C.

Yes, the paddlewheel of the DST800 speed sensor is designed to be easily replaceable. This allows maintenance and replacement of this wear part without having to remove the entire transducer from the hull.

The weight of the DST800 analog triducer is approximately 1.4 kilograms.

The triducer itself is primarily passive for depth and speed functions. However, the integrated temperature sensor may require a small supply voltage, which is usually provided by the compatible display instrument or the converter to which the triducer is connected.

The DST800 analog triducer is designed for through-hull installation. This means it is mounted through a hole drilled in the boat’s hull, with the transducer face flush with the hull’s exterior for optimal performance.

For the through-hull installation of the DST800 triducer, a hole with a diameter of approximately 51 mm (2 inches) is typically required in the boat's hull.

Yes, for optimal performance, it is recommended to install the depth sounder in an area of the hull where the water flow is most laminar and free of air bubbles. Avoid areas near propellers, keels, water intakes, or any element that could create turbulence. The ideal location is typically toward the bow of the boat, away from sources of noise.

As an analog tri-sensor, the DST800 is compatible with dedicated analog display instruments that can directly interpret its raw signals. To integrate it into more modern systems, it requires an analog-to-digital converter.

No, the DST800 analog triducer does not output NMEA 2000 data directly. It generates raw analog signals for depth, speed, and temperature. To integrate it into an NMEA 2000 network, an analog-to-digital converter is required.

To integrate the DST800 analog triducer into an NMEA 2000 network, you will need a compatible analog-to-digital converter. Examples include the Raymarine iTC-5 module or dedicated converters like the Airmar ST900/P79, which convert analog signals into digital data usable by modern multifunction displays (MFD).

The DST800 triducer package typically includes:

The DST800 analog triducer with its integrated cable. A nut and washers for through-hull mounting. A blanking plug to seal the transducer hole when the paddlewheel is removed for maintenance. A fairing block may also be included for installations on inclined hulls.
