Abstract
The invention concerns a tensile testing sensor mounted on a mechanical member wherein forces to be measures develop comprising a bendable metal blade (1, 22) provided with measuring gauges (2, 23) implanted and positioned on the blade. Said blade (1, 22) is sensitive to mechanical tensile and compressive deformations sustained and transmitted via two bearing parts (4, 5, 20) coupled to the mechanical member wherein the forces develop. The sensor is equipped with a mechanically locking flange (31) placed during calibration between the bearing parts (4, 5, 20) and the sensor blade.
Claims28
A tensile testing sensor mountable on a mechanical member in which forces to be measured develop, comprising a bendable flat metal blade provided with measuring gauges implemented and positioned on the blade and equipped with a temporary and removable mechanically locking flange placed during calibration between the bearing parts of the sensor blade, said blade being sensitive to mechanical tensile and compressive deformations sustained and transmitted via two adjustable bearing parts in relation to the mechanical member in which forces develop, said temporary flange being removed from said sensor after said sensor is mounted on said member, whereby said flange is used to lock said blade into a calibrated position during said calibration and installation and is removed when said sensor is mounted on said member and said sensor is used to measure forces.
A tensile testing sensor mountable on a mechanical member wherein forces to be measured develop, comprising a flat elastic blade in isostatic support on its ends between to adjustable abutments and kept in flexion by buckling, means to measure the deformation of the part by which the adjustable abutments are joined integrally;
- wherein said abutments adjusted to calibrate buckling of said blade prior to final mounting of said sensor to said member.
A method of calibrating a tensile testing sensor mountable on a mechanical member wherein forces to be measured develop comprising:
- providing two adjustable bearing parts mountable in relation to the mechanical member;
- placing a bendable flat metal blade having measuring gauges between said two adjustable bearing parts, said blade being sensitive to mechanical tensile and compressive deformations sustained and transmitted via the two adjustable bearing parts;
- during calibration, placing a temporary mechanically locking flange and locking said blade between said bearing parts;
- mounting said sensor on said member;
- removing said temporary flange from said sensor after said sensor is mounted on said member;
- whereby said flange is used to lock said blade into a calibrated position during said calibration and installation and is removed when said sensor is mounted on said member and said sensor is used to measure forces.
