ABSTRACT:
The invention relates to a portable simulator for bathymetric probes of the thermometric or calorimetric types connected at the output to an acquisition card. The simulator has at least four circuits corresponding, respectively, to the following four functions: a) selecting a probe type (thermometric or celerimetric) and establishing a firing sequence; b) generating a periodic signal of variable frequency to simulate a celerimetric type probe; c) generating a variation in temperature to simulate a thermometric probe; d) detecting a supply voltage threshold, with circuits b and c having a common section ending at the input of the acquisition card.
