Detail

A preamplifier is built into the sensor for stable and long-distance transmission (max.300m long) of the current signal.
The EML500 can receive a backup signal(NMEA-0183) from external speed sensors such as a GPS receiver.
A dual-axis sensor (optional) measures a ship's transverse speed as well as its longitudinal speed.

Measurement Range	Speed	-4 to 20 kt -5 to 25 kt -7 to 35 kt -8 to 40 kt -10 to 50 kt -13 to 65 kt
	Distance	0 to 9999.99 nm
	Direction	0 to 359 deg. (For dual-axis)
Accuracy	Speed	±0.2 kt or 1% of reading whichever larger
	Distance	±0.05 nm/h or ±1% whichever larger
	Direction	±2.5 deg. (For dual-axis)
Power Supply	100/220V AC 50/60Hz single-phase
Signal Inputs	NMEA-0183 (For back up signals from external speed sensors such as GPS)		1 circuit
Signal Outputs	Speed	Voltage: 0 to 5V DC or 1 to 5V DC	2 circuits
