(Summary description) Force is the direct cause of changes in material motion, and force sensors can detect mechanical quantities such as tension, tension and compression, weight, torque, internal stress and strain. The force sensor is usually composed of a sensitive element and a conversion element, which is a device or equipment that can sense the specified measurement data and convert it into usable signals according to certain rules. Force sensors have been widely used in this new era, and are now widely used in the industrial field. In order to use the force sensor well, it is necessary to have a certain understanding of the definition and function of the force sensor. So, what is a force sensor? What are the types? Let's take a look! There are many kinds of force sensors, which can be divided into resistance strain sensors, piezomagnetic sensors and piezoelectric sensors according to different physical effects and detection principles. 1, strain type force sensor. Strain gauge force sensors are widely used in all force sensors. It has high measurement accuracy and can measure dynamic and static forces from small to large, and its usage accounts for about 90% of the total sensor. The working principle of the strain gauge force sensor is basically the same as that of the strain gauge pressure sensor, which is also composed of an elastic sensitive element and a strain gauge attached to it. The strain gauge force sensor first converts the measured force into the strain of the elastic element, and then reads the output by measuring the strain using the resistance strain effect. 2, voltage power sensor. When a ferromagnetic material is strained and pressed by an external force, its permeability will change with the magnitude and direction of the stress. When the tension acts, the permeability increases along the direction of the force, but decreases slightly in the direction of the vertical force, and the change of the permeability under pressure is just the opposite. This physical phenomenon is the piezomagnetic effect of ferromagnetic materials, which can be used for force measurement. 3. Piezoelectric sensor. Piezoelectric sensors can measure various dynamic forces, mechanical shock and vibration, and are widely used in the fields of acoustics, medicine, mechanics and navigation, with small size, light weight, high frequency response and high signal-to-noise ratio. According to the shape, the load cell can be divided into cantilever load cell, S-shaped load cell, plate load cell, box type load cell and spoke type load cell. Force sensors have penetrated into a wide range of fields, such as resource survey, ocean exploration, space development, industrial production, environmental protection, medical diagnosis, bioengineering, and even cultural relics protection. Force sensors have long penetrated into a wide range of fields, such as resource survey, ocean exploration, space development, industrial production, environmental protection, medical diagnosis, bioengineering, and even cultural relics protection. It is no exaggeration to say that almost every modern project, from the vast space, to the vast ocean, to a variety of complex engineering systems, can not be separated from a variety of force sensors.
