Electromagnetic log LI2-1
Electromagnetic log for measuring speed made good through the water is designed in full compliance with the requirements of IMO and Sea Register of Russia for use on ocean-going vessels and hovercrafts.
The log has high accuracy and stability of measurements, supplies data to ship's navigation systems and provides number of additional services.
The log consists of main processor (, unit) and receiving device which may be one of two types:
  • gate valve type installed on the level with the vessel's bottom (-1 unit);
  • receiving device installed stationary on the underwater wing (-2 unit).
    • The log complectation may include speed repeaters (PC1-T unit) and speed and distance repeaters (PC1-TT unit):
  • up to 3 pieces without information splitter;
  • up to 9 pieces with the information splitter (unit 59).

    • Main technical characteristics:
    Speed measurement range, knots from -6 up to +50
    Speed measurement accuracy:
      shore trials, knots +0,1
      ship's trials, % 1,0 - 1,5
    Distance measurement range, miles from 0 up to 9999,9
    Distance measurement accuracy, % +0,1
    Input power, Watt 50
    Power source 110 or 220 V, 50 Hz

    Additional services
    Input or distance settings, miles from 0 up to 999,9
    Time measurement of covered distance up to 99 hrs 59 min
    Medium speed calculation on 6 min interval
    Input or current correction, knots from -4 up to +4
