    摘要: A device (1) for detecting physical variables of a fluid comprises a body (2) with associated two capacitive sensors (22-23; 22-24) to detect the level and a reference parameter of the fluid, respectively. Each sensor comprises at least two respective electrodes (22, 23; 22, 24) obtained from a metallic lamina and defining at least a respective plate surface facing an homologous plate surface of the other electrode. The electrodes (22, 23) of a sensor have at least a plate surface formed in the thickness of a respective lamina, while the electrodes (22, 24) of the other sensor have at least a plate surface defined in at least a main face of a respective lamina.
