Abstract: Disclosed is a “factor 1” and inductive sensor device including an LC resonant circuit powered by a suitable generator, an operational chain of units for acquisition by sampling and processing of the response signal, and a functional set of units for evaluating at least one temporarily set value of the processed signal and supplying detection or non-detection information. The acquisition and processing unit includes analog a unit for filtering and/or amplifying the sampled response signal, and a unit for compensating the temperature drift of the response signal by correcting the sampled signal following the digital conversion thereof, associated with or including a temperature sensor.

Abstract: A method for communication, intended in particular for the purpose of a configuration, calibration, parameterization, interrogation or even a test or diagnosis, between a master device and a slave product including at least a processing unit and a direct current power supply line or input, and, if necessary, at least one output line and/or output interface. The method includes transmitting to the product data that can be interpreted by the processing unit thereof, the data being transmitted via the power supply line and by modulating the supply voltage.

Abstract: A device for detecting metal elements in slab form such as metal plates or sheets, includes an emission coil powered by suitable control elements and generating a magnetic field, a reception coil placed so as to enable generation via induction of a voltage across the terminals of the coil under the action of the magnetic field, and elements for processing and evaluating the voltage signal delivered by the at least one reception coil, enabling delivery of an information signal indicating the absence or presence of one or more metal elements near the coils. The emission coil (3) and the reception coil (5) are both mounted in a housing or a sensor head having an active detection face having an associated detection region, and are positioned at a defined inclination one relative to the other and relative to the face.

Abstract: An electronic device, in particular of the sensor or detector type, includes a housing having first and second longitudinal opposite and sealed ends. The housing contains an electronic card and with its inside volume being filled by an insulating filler material that coats the card, its components, and the end of a connecting cable connected to the card, the housing including an opening at its second end, which is sealed by a connected piece that is equipped with a passage opening for the connecting cable. The sealing piece includes at least a second through opening for injecting filler material (5), this or each second opening being sealed by a plug (9) made of a material that conducts and diffuses light, of which a portion is positioned in the vicinity of, and even in contact with, at least one light signaling element (10) or light indicator carried by the card (4).

Abstract: A sensor or detector device includes a box in the form of a tubular hollow body, through whose opening a connecting cable passes and that is sealed by a connected plug. The device also includes a card or an analogous substrate, carrying the electronic components of the sensor or detector and mounted in the box, by being coated by an insulating filler material filling approximately the entire remaining inside volume of the latter. The Device (1) is characterized in that it includes a mechanical element for the positioning with wedging of the card (6) in the box, preferably along a median plane or with longitudinal symmetry (PM) of the latter, with at least a portion of the element being integrated in the plug (5).
