Abstract: A support base for a measuring cell including a base plate with a bore and an annular groove defined therein, and a planar pressure surface machined therein. A load pin is connected to the base plate to provide articulated support for a load. The load pin has a threaded shank adaptable to adjust its height relative to the measuring cell and terminates in a pressure head with a convex pressure surface and an annular groove defined therein. The pressure head of the load pin is inserted with play into the bore of said base plate. A resilient ring is disposed between the annular grooves to connect the base plate and the pressure head.
