摘要： The present invention relates to strain gauges, in particular to strain gauges used to determine a force on welding gun used for spot welding in automated assembly lines. A claimed strain gauge for welding gun comprises a housing that consists of at least two portions forming a single closed internal shielded space; a sensing element comprising one resistive strain sensor or at least two resistive strain sensors combined into a strain gage bridge, wherein said sensing element is arranged on an inner surface of one of the portions of the housing, wherein said housing portion has a material thinning in the area of the sensing element, wherein said sensing element is arranged between housing supports of the strain gauge, wherein the housing supports are arranged on the portion of the housing and are made of electrically non-conductive material of high rigidity, wherein a height of the housing supports is such that there is no contact between the housing and a surface of the welding gun; a ground line of the force data output device having a galvanic contact with at least one of the portions of the housing; the communication line connecting the sensing element with the force data output device comprises a damping bend. The technical effect achieved by the claimed strain gauge is its noise immunity and the ability to its operation under complex electromagnetic environment.

摘要： An electromagnetic coupling sensing device includes a frequency generation module, a first resonant module, a second resonant module, and an echo acquisition and processing module. The first resonant module generates a primary resonant signal based on the frequency setting signal generated by the frequency generation module. The second resonant module couples with the first resonant module through a coupling capacitance to generate a secondary resonant signal based on the primary resonance signal. The second resonant module includes a coil. A ferrite is provided in the coil and a height of the coil is higher than the ferrite. The coil is capable of carrying a weight to be measured to deform such that an intrinsic frequency of the electromagnetic coupling sensing device changes. The echo acquisition and processing module collects the secondary resonant signal and outputs a voltage signal changing according to the intrinsic frequency.
