DT800 Smart™ Sensor
Depth and Temperature
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. It is sold with a choice of
rugged housings—plastic, bronze, or stainless steel—to accommodate any vessel
type or hull material. 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.
Available in three Tilted Element™ models:
- Fixed 20° tilted version for 16° to 24° hull deadrise
- Fixed 12° tilted version for 8° to 15° hull deadrise
- Fixed 0° tilted version for 0° to 7° hull deadrise
Features
- Depth and temperature
