DISPOSITIF DE DETECTION DES VARIATIONS CLIMATIQUES LOCALES SUSCEPTIBLES NOTAMMENT DE PROVOQUER DES DETERIORATIONS DE MATERIELS ELECTRIQUES |
摘要 |
<p>The system uses a programmer (2) which initiates sequentially a resistivity probe (1) comprising a megohmmeter (3) with an adjustable threshold. This is connected to the probe and is associated with a metallic mars (1a) of given specific heat capacity. The megohmmeter is also connected to a flashing lamp (4) and sound alarm (5) and to the telephone system using an automatic coded call system. A radio signal is also generated. The detector system is housed in two compartments of an enclosure. The lower compartment contains the detector probe and is insulated from thermal effects. Louvres permit circulation of air. The upper compartment contains the various alarm systems and the programmer.</p> |
