A load measuring device for a railcar bogie in which a vibrationproof rubber between an axle box and a bogie frame includes a vertical load fluctuation sensor in parallel with the vibrationproof rubber and configured to deform in conjunction with elastic deformation of the vibrationproof rubber in a vertical direction, the vibrationproof rubber supporting a downward load from the bogie frame. The vertical load fluctuation sensor changes an electric output by the deformation of the vertical load fluctuation sensor in conjunction with the elastic deformation of the vibrationproof rubber in the vertical direction.

An assembly line grow pod includes a seeding region, a harvesting region, a track that extends between the seeding region and the harvesting region, a cart including a tray for holding plant matter, and a wheel coupled to the tray, where the wheel is engaged with the track, and a weight sensor positioned on the cart or the track, where the weight sensor is positioned to detect a weight of the plant matter positioned within the cart.

A weighbridge for weighing a ladle transfer car has a foundation pit, a weighing platform, and a plurality of load cells. The foundation pit has a base and the weighing platform, positioned in the foundation pit, bears upon the base. The plurality of load cells are arranged in the foundation pit to collectively bear the weight of the weighing platform. A characterizing feature of the weighbridge is that, during use, the foundation pit contains a liquid, with a level that is maintained to at least partially submerge each of the load cells.
