摘要： A top-pan balance having a pan, a weighing system, and an overload safety mechanism. The load cell (4) of the weighing system is connected to fixed points (1) on a housing of the weighing system by an upper connecting rod (2) and a lower connecting rod (3) as a parallel guide so as to be movable in the vertical direction. The pan is attached to a pan support (8/9) for securing against overload, the support being connected to the load cell through an auxiliary parallel guide (15/16) and through a biased spring element (17/18), whereby the pan is quasi rigidly coupled to the load cell in the permissible weighing range, but is only resiliently coupled to the load cell when the permissible weighing range is exceeded. At least one limit stop is fixed to the housing and limits the elastic deflection of the pan and the pan support in case of overload. An additional corner load sensor is provided between the pan support and the load cell, and the corner load sensor and the overload safety mechanism form a common assembly (7), wherein the corner load sensor is disposed behind the overload safety mechanism in the force flow direction from the pan to the load cell. Furthermore, the assembly is attached on the side of the load cell facing the connecting rods and extends into the space between the connecting rods.

摘要： A precision force transducer having a spring element (1) whose load-dependent deflection is converted into an electrical signal by means of strain gauge elements (10). The spring element (1) is made of a precipitation-hardenable nickel-based alloy with a nickel content in the range of 36 to 60 percent and a chromium content in the range of 15 to 25 percent. The strain gauge elements (10) are composed of a polymer-free layered film system. This makes it possible to produce a precision force transducer that features great accuracy, low creep and low moisture sensitivity.
