The present disclosure is directed to a machine for filling at least one container with a pourable product. The machine includes a conveyor; at least one filling unit configured to engage the at least one container; and a weighing device coupled to the at least one filling unit and configured to provide weighing information related to a weight of the at least one container during a filling operation. The weighing device includes a support unit having a supporting arm configured to hold the at least one container and configured to be elastically deformed as a function of the weight of the at least one container being filled; and a sensing unit configured to provide a contactless sensing, wherein the sensing unit is configured to detect a distance from the supporting arm to a portion of the machine facing the supporting arm, the weight of the container being a function of the distance.

Transport rail system capable of detecting a weight of a rail vehicle, includes one or more rails, and one or more sensors for measuring a magnetic property. At least one of the sensors is adapted to measure a change of a magnetic property in order to determine a weight bearing on one or more of the rails, the change of the magnetic property being caused by stress exerted on the rail by the weight, and one or more of the sensors are adapted to measure the change of a magnetic property of the rail itself and/or that one or more of the sensors are adapted to measure the change of a magnetic property of a supporting structure of the rail.

An electromagnetic coupling sensing device includes a frequency generation module, a first resonant module, a second resonant module, and an echo acquisition and processing module. The first resonant module generates a primary resonant signal based on the frequency setting signal generated by the frequency generation module. The second resonant module couples with the first resonant module through a coupling capacitance to generate a secondary resonant signal based on the primary resonance signal. The second resonant module includes a coil. A ferrite is provided in the coil and a height of the coil is higher than the ferrite. The coil is capable of carrying a weight to be measured to deform such that an intrinsic frequency of the electromagnetic coupling sensing device changes. The echo acquisition and processing module collects the secondary resonant signal and outputs a voltage signal changing according to the intrinsic frequency.
