AIRMAR Smart DT800 235 kHz Bronze with Value NMEA 0183 Version Depth and Temperature Sensor|DT800BV-235-0

AIRMAR DT800BV-235-0, DT800 Low-Profile NMEA-0183, Smart™ Sensor


The DT800 utilizes Airmar’s proven Tilted Element™ and broadband technologies in this thru-hull depth and temperature Smart™ Sensor. The DT800 is a low profile, retractable, thru-hull sensor that computes accurate depth and temperature data and sends it to any NMEA 0183 or NMEA2000® display or network. Airmar’s Smart™ Sensors have embedded microelectronics the transducer element and signal processor are only millimeters apart. The signal from the depth transducer is processed right inside the sensor itself. All that is needed to receive depth and temperature data is a single cable into a compatible network or display. The ceramic is tilted inside the housing, which compensates for hull deadrise and orients the transducer beam straight down, resulting in strong bottom echo returns and accurate depth readings. These low profile housings do not affect hull performance and will provide accurate readings at high speeds. The retractable housing with a self-closing valve reduces water flow into the vessel when the transducer is removed for cleaning.
