1. DESCRIPTION

ANTHEA is a new generation of electromagnetic log. For standard operation, it uses model
48 BEN 48mm flat-surfaced sensors. It can be adapted to other BEN sensors having the same
electrical characteristics.
ANTHEA includes a high and low speed alarm, controlling a visual and/or acoustic alarm if
required. This alarm can be acknowledged and stopped via front panel keyboard.
This alarm is very useful on board trawlers. Indeed, any strain modification of the net is
detected faster and in a more accurate way via speed measuring than by traction effort
measuring.
It is also used to keep a speed considered as economical or to keep a mandatory speed.
ANTHEA includes an automatic gain adjustment for optimum accuracy. A permanent self-
test indicates any possible log faults on LCD screen.
