Simulator i lett bµrbar utf÷relse, for Õ simulere batymetrisonder

摘要

The invention relates to a portable simulator for probes bathymetric of the thermometric or celerimetric connected on output to an acquisition card, characterized in that it comprises at least four circuits, respectively, corresponding to the four following functions: & br / a) selection of a type of probe (thermometric or celerimetric) and the putting in place of a firing sequence, & br / b) generating a periodic signal of variable frequency to simulate a celerimetric type probe, & br / c) the generation of a variation of temperature for the simulation of a thermometric probe, & br / d) detection of a supply voltage threshold, the circuits b and c with a common section terminating at the inlet of the acquisition card.
