Abstract

Cette invention concerne un émetteur prévu sur un rabot à charbon guidé le long du front de taille. Cet émetteur est placé dans un boîtier de protection en forme de barreau qui est logé amoviblement dans un perçage de réception du rabot placé au-dessus du guide du rabot. Seule la surface de ce boîtier servant au rayonnement des impulsions émises est exposée. Cet émetteur est utilisable comme commutateur de fin de course radioélectrique ou comme dispositif de mesure de la course du rabot.
