This type is suitable for general merchant vessels, and accepts both flush-mountable and dual-axis sensors.
- 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.
