Abstract

Improvements in the construction of presence and passage detectors of objects, in particular of vehicles, of the type of flexible pipe filled with gas disposed on the passage of the object and of the pneumatic sensor which receives the pressure wave caused by the momentary crushing of the pipe to the passage of said object, characterized in that said detectors comprise two flexible and identical pipes, arranged parallel to one another, each having a first open end portion connected to said sensor and one of them having its second portion closed end, and the other its second end portion open, in order to obtain a single impression of the pneumatic sensor to each crushing of the pipes.
