A strain gauge is a component composed of a sensitive grid, etc., used to measure strain. The working principle of the resistance strain gauge is based on the strain effect, that is, when the conductor or semiconductor material is mechanically deformed under the action of external forces, its resistance value changes correspondingly, which is called the "strain effect".
There are many kinds of strain gauges. The general strain gauge is a plastic film called the base (15-16μm) pasted with a sensitive grid (3-6μm) made of thin metal foil, and then covered with a layer of film to make a laminated structure.
Strain gauges are mainly used in sensors. The effect of vibration aging depends on the choice of vibration type. In order to ensure the accurate elimination or reduction of the residual stress in the key parts of the workpiece, to prevent welding, cutting, casting, forging, machining deformation and cracking. Developed a variety of conventional aging equipment, can provide users with scientific process mode analysis, convenient equipment operation functions, in order to qualitatively ensure the aging process effect... They can be divided into 4 series and 16 specifications.
A device or component that can convert the measured physical or chemical quantity into electricity is called a sensor (also known as a converter), in which we usually contact more physical quantities are temperature, humidity, mass, weight, force, pressure, speed, acceleration, length, Angle, liquid level, flow, density, etc.; Corresponding to this, production and life need temperature sensors, humidity sensors, weighing force sensors, pressure sensors and so on.
