  • Patent number: 6082203
    Abstract: The invention relates to a sensing element for measuring loads. According to the invention, the sensing element commprises: a strain transducer unit (1) measuring the strain in a structure, including a strain transducer element, such as a strain gauge element (6); and a protecting shell (2) inside which the strain transducer unit (1) is fitted and which protecting shell includes: a base plate (3), on top of which the strain transducer unit (1) is attached; and a protecting hood (4) which is fitted around the strain transducer unit (1), on top of the base plate (3). The protecting hood (4) is most advantageously filled with protecting material (5), such as silicon.
