Airmar DT820BV-235-N2 235 kHz Low Profile Tilted Element Smart Sensor 20 Degree Tilt Bronze NMEA 2000

The Airmar DT820BV-235-N2 Smart™ Sensor is a cutting-edge, low-profile depth and temperature sensor engineered for marine and boating applications. Utilizing advanced Tilted Element™ technology and operating at a stable 235 kHz frequency, this sensor delivers precise and reliable data to your NMEA 2000® or NMEA 0183 compatible displays, enhancing your vessel's navigational capabilities.

Product Overview

The DT820BV-235-N2 is designed for seamless integration into a variety of marine environments. Its retractable, thru-hull installation minimizes drag and ensures easy maintenance, while the self-closing valve prevents water ingress when the transducer is removed for cleaning. This smart sensor can operate concurrently with other Airmar transducers (50/200 kHz) without causing interference, thanks to its unique broadband ceramic technology.

Advanced Tilted Element™ Technology

Airmar's proprietary Tilted Element™ ceramic technology ensures optimal performance across different hull deadrise angles. By tilting the transducer beam straight down, the sensor achieves strong bottom echo returns, providing accurate depth readings even in challenging marine conditions.

Smart™ Sensor Features

• Enhanced Depth Performance: Achieves a maximum depth range of 180 meters (594 feet) and accurate shallow-water readings from as little as 0.5 meters (1.6 feet).
• High Sensitivity: The urethane face enhances sensitivity for more precise measurements.
• Excellent High-Speed Performance: Maintains accuracy in dynamic marine environments.
• Fixed Tilt Options:
  • 20° tilt for 16° to 24° deadrise
  • 12° tilt for 8° to 15° deadrise
  • 0° tilt for 0° to 8° deadrise
• NMEA 2000® Output: Ensures seamless data integration with compatible marine electronics.
• Reliable Power Handling: Supports up to 100 W RMS power for robust performance.
• Interference-Free Operation: The 235 kHz frequency eliminates interference with onboard fishfinders and other electronic devices.
• Retractable Housing: Facilitates easy serviceability and protects the transducer when not in use.
• Compact Design: The 51mm (2") housing accommodates hull thicknesses from 6.3mm (0.25") to 54mm (2-1/8").
• Included Accessories: Comes with a blanking plug and a 0.6m (19.8') NMEA 2000® Devicenet cable and connector.
• Usable Shaft Length: 57mm (2.25") for versatile installation options.

Embedded Microelectronics

The Smart™ Sensor integrates microelectronics directly within the transducer housing, keeping the transducer element and signal processor just millimeters apart. This proximity allows for immediate processing of the depth transducer signals inside the sensor, ensuring fast and accurate data transmission through a single cable to your marine display or device.
