EM Log SAM

The SAM EM Log is an electromagnetic speed log that measures vessel speed through water by detecting the voltage induced in a magnetic field, offering high accuracy without moving parts. As a Speed Log, it is normally installed on the bridge with the required external sensors, antennas, displays and data-network interfaces. In that role, its primary purpose is to provide navigation, position, heading, speed, depth, traffic or bridge-management information according to the listed category. Radar, ECDIS, gyrocompass, GNSS, speed log, echo sounder and integrated bridge systems use different sensing principles, so calibration and interfaces must match the actual installed equipment. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
