DT800

Smart™ Sensor Tilted Element™, Thru-Hull Transducer

Features

• Tilted-Element Broadband-Ceramic versions available in plastic, bronze, or stainless steel housings in a 0° or 12° or 20° tilt

• Available in NMEA 0183 and NMEA 2000® versions

• 235 kHz frequency prevents mutual interference with other echosounders on the vessel

• Temperature sensor in DT800 models

• Cable lengths up to 100m (330’) are possible with no loss of performance—NMEA 0183 only

• Available in low-profile, countersunk, or beveled-edge housings

Clever Alternative!

Airmar’s Smart™ Sensors feature embedded micro-electronics.

Depth, speed, and temperature signals are processed inside the sensor and can be displayed on any radar, chart plotter, or device that accepts NMEA data. Airmar Smart Sensors are available with NMEA 0183, NMEA 2000®, or customer specific CAN protocols.

Angle for Results Airmar has added Tilted Element™ technology to the Smart Sensor line. The Tilted Element Transducer’s low-profile housing compensates for hull deadrise. The unique design tilts the ceramic element inside the transducer housing—giving all the advantages of a fairing block without a hull protrusion.

Designed with Airmar’s exclusive Broadband Ceramic Technology, the 235 kHz element improves resolution without sacrificing sensitivity. The higher power rating 100 W RMS provides spot-on depth readings in as little as 0.45 m (1.4’) of water and can reach depths up to 180 m (600’).
