The present invention provides a measuring sensor (30) for measuring the presence of liquid having a relatively low electrical resistance (of the order of 0-1000 .OMEGA.) comprising one or more conductors with high electrical resistance (of the order of 100 k.OMEGA. or more) which are maintained between connecting contacts on a carrier element made of synthetic material, cardboard or paper and which has a substantially meandering shape, wherein the resistance between the connecting contacts is notably reduced in the presence of the conducting liquid.
Capteur (30) de mesure de la présence d'un liquide présentant une résistance électrique relativement faible (de l'ordre de 0 à 1000 OMEGA ). Le capteur comporte un ou plusieurs conducteurs présentant une résistance électrique élevée (de l'ordre d'au moins 100 k OMEGA ), et s'étendant entre des contacts de connexion sur un élément support en matière synthétique, en carton ou en papier, ledit élément étant muni de pistes conductrices sensiblement sinueuses, et la résistance entre les contacts de connexion étant sensiblement réduite en présence du liquide conducteur.
