Definitions

  • FIG. 5 shows a first bridge circuit for detecting longitudinal mechanical stresses on the first deformation body
  • a bridge circuit 6000 shown in FIG. 6 is provided in the electrical assembly on the deformation body.
  • strain gauge structures of the two different interconnect layers 2008 and 2016 are interconnected.
  • the strain measurement structures of the two respectively adjacent deformation regions 1018 and 1020, 1022 and 1024, and 1026 and 1028 of the deformation body 1000 from FIG. 1 are connected in series, resulting in an increased sensitivity of the circuit arrangement.
  • the bridge circuits 5000 and 6000 corresponding bridge circuits are in the deformation body 1000 of Figure 1 for all deformation sections 1018, 1020; 1022, 1024 and 1026, 1028 provided.
  • FIG. 7 shows a further, alternative bridge circuit 7000, which is designed as a half-bridge circuit and makes it possible to detect a bending stress of a deformation section on the deformation body 1000 from FIG. 1.
  • the bridge circuit 7000 compares the electrical resistances R 30 So and R3100 of the strain gauge structures 3080 and 3100 from a deformation range of the deformation body with the electrical resistances R 3084 and R 3 -I 04 of the strain gauge structures 3084 and 3104 located in a compensation area of the deformation body , In the bridge circuit 7000 are thus connected Dehnmess füren from two different interconnect layers of the deformation body.
  • FIG. 11 shows a force-moment sensor deformation body 11000 designed to detect bending forces F, shear forces Q acting according to arrow 11016, and torsional moments M to axis 11012.
  • This deformation body is a printed circuit board 11002, which contains an electrical assembly 11004 for the evaluation of strain gauge structures, which are formed in the form of printed conductors in layers of the printed circuit board.
  • the circuit board 11002 has a bending area 11006, which can also be performed with reduced material thickness. In the bending region 11006, lateral recesses 11008 and 11010 are formed. This measure causes a very uniform stress distribution in the deformation body.
