Active Transducers TDR
 
 
 
Powerful digital signal processor
A high-speed microcontroller capable of 10 million instructions per second, and a large memory to handle the advanced digital signal processing techniques required to calculate the depth of water below the vesel, vessel speed, distance travelled and water temperature.
 
Class leading depth performance
Depth performance in a class of its own, with an industry leading shallow depth capability of just 0.3 metres / 1 foot (below 10 knots), and a maximum depth of 200 metres (depending on the transducer type).
 
Proven depth algorithm
The depth processing algorithms have been fine-tuned over an 8 year period and represent the best-in-class available for calculating the correct depth, even under difficult conditions - at speed, with layers of algae, turbulence and interference from other vessels.
 
Low interference depth frequency
235kHz is a new, rarely used frequency that suffers from very little interference from other depth sounders, and can provide a higher accuracy tracking of the seabed.
 
Speed tracking algorithm
Speed calculations can accurately track even the smallest changes in vessel speed, with a resolution of 0.1 knots.
 
Temperature algorithm
A built-in thermistor can precisely measure the water temperature around the transducer, with a 0.1°C resolution.
 
 
Carefree operation
The dynamic electronics are completely sealed against water ingress for carefree operation.
 
NMEA 0183 full-differential output driver
Can drive up to 4 fully compliant NMEA 0183 device loads, with a 10mA (maximum) drive capability. The full-differential output ensures better quality communications and lower noise emissions on unshielded twisted pair cabling. Simply wire to a device capable of showing NMEA information to view all the NMEA data.
 
NMEA 0183 sentences output
Depth (DBT and DPT), Speed (VHW), Distance Log (VLW) and Water Temperature (MTW) sentences are output once per second.
 
Wide battery input voltage range
For maximum compatibility, any battery supply between 11 and 28 volts can be used.
 
Very low current consumption
Ideal for small vessels with small batteries.
 
Customise service available
Actisense™ offers a full user configuration service for the Active Transducer range. The transducers can be fine tuned to match each customer's individual requirements - be they different Baud rates, faster/slower data output rates, and/or specific data output formats.
