Electromagnetic Log – speed through water – with no moving parts!
The EML-2 electromagnetic speed log measures the boat speed through the water with no moving parts.
Robust and accurate, the sensor generates an alternating magnetic field below the boat and measures the resulting electric field produced by the boat moving through the water.
With excellent linearity and a resolution of 0.1 Knot, over the range 0.2 to 40 Knots, the control box converts the sensor signal to boat speed, trip and total distance and sends it to any compatible NMEA-0183 display.
For a complete solution the EML-2 electromagnetic transducer and controller can be supplied together with either a
Clipper EM log display
Target EM log display
or to a
NMEA 2000 backbone via our converter
EML -3 is a pulse output version of the Electromagnetic Log to suit any previous NASA Marine paddlewheel log including all Target, Clipper Logs and Duet. Also works with Raymarine ST60 Log display.
