SIGNAL LOG [6 records]

Record 1 2023-05-31

English

Subject field(s)
  • Electrical Measuring Equipment
  • Water Transport
CONT

The... electromagnetic speed log measures the boat speed through the water... the sensor generates an alternating magnetic field below the boat and measures the resulting electric field produced by the boat moving through the water.... the control box converts the sensor signal to boat speed, trip and total distance and sends it to [a] compatible... display.

Key term(s)
  • electro-magnetic speed log
  • electro-magnetic log

French

Domaine(s)
  • Appareils de mesures (Électricité)
  • Transport par eau
CONT

L'objectif d'un loch électromagnétique est de calculer et d'afficher la vitesse et la distance parcourue sur l'eau par un bateau afin que l'équipage puisse obtenir des informations fiables et en temps réel pour ajuster sa navigation. Le système est nécessaire au fonctionnement du navire et apporte des informations clés au système de navigation.

Record 2 2011-07-20

English

Subject field(s)
  • Maneuvering of Ships
  • Sonar and Underwater Detection (Military)
CONT

The longitudinal and the lateral speed of the ship may be measured by means of a sonar doppler log which operates on the principle that a sonar signal transmitted from a moving object and reflected back from a stationary surface will indicate a shift in frequency; this shift in frequency is proportional to the speed relative to the stationary surface of the moving object, which in this case will be the ship.

Record 4 1996-04-04

English

Subject field(s)
  • Analytical Chemistry
CONT

... monochromatic UV photometer available from Du Pont; similar designs are widely used in modern LC. UV radiation at 254 nm from a low-pressure mercury lamp shines on the entrance of a flow cell and is transmitted through this sample cell and strikes the analytical prototube. Radiation from the source also is directed through a neutral-density filter, and then to the reference photocell. Current from these photocells is fed to log amplifiers, which generate an output linear with solute concentration. The output signal to the recorder normally is attenuated with a simple bridge network.

Subject field(s)
  • Electrical Circuits and Circuit Breakers
  • Telecommunications Transmission
DEF

the actual relative level at a point on a circuit is the expression 10 log(exponent) 10(P/P(exponent) 0) dBr, where P represents the power of a sinusoidal test signal at the point concerned and P(exponent) 0 the power of that signal at the transmission reference point.
