Abstract:

STS OF THREE MAIN PARTS - A STRUCTURAL MEMBER TO ESTABLISH A RELATIONSHIP BETWEEN LOAD AND DEFORMATION, A FLUIDIC STRAIN GAGE TO PRODUCE A FLUIDIC SIGNAL AS A FUNCTION OF THE DEFORMATION, AND A THREE-STAGE LAMINAR PROPORTIONAL AMPLIFIER GAIN BLOCK TO RAISE THE STRAIN-GAGE OUTPUT TO A USEFUL LEVEL. The load cells built have load ranges of about 0 to 20 kN with a discrimination of about 1 percent of full scale in compression typical full-scale output pressure of the devices built is about 30 Pa at a 20 kN load. The output is fairly linear thus, it can be used directly as indication of the load magnitude. Load-cell designs have been conceived, although not implemented for operation in tension and in both tension and compression. Author
