There are many factors affecting the stability of force sensor, which can be summarized as follows: 1. Structure of force sensor The design of the elastic element, shell, diaphragm and upper pressure head and lower pressure pad of the force sensor must ensure that the performance fluctuation does not occur in the structure after loading, or the performance fluctuation is very small. Therefore, when designing the force sensor, the stress in the strain area should be single and uniform as far as possible. The patch site is best flat; In the structure to ensure a certain degree of anti-eccentric load and lateral load capacity; The mounting force is far away from the strain zone, and the displacement of the load bearing point should be avoided during measurement. Although force sensors are manufactured by assembly, they are designed as a whole structure to ensure the best technical performance and long-term stability. 2. Metal materials for elastic components The metal material of elastic element plays a key role in the comprehensive performance and long-term stability of force transducer. Materials with high strength limit and elastic limit, good time and temperature stability of elastic modulus, small elastic hysteresis, and low residual stress caused by mechanical processing and heat treatment should be selected. Data show that: as long as the plasticity of the material after quenching is good, its residual stress after mechanical processing and heat treatment is small. Special attention should be paid to the stability of elastic modulus with time, and the elastic mold of the material should not change during the service life of the force sensor. 3. Mechanical processing and heat treatment process In the machining process of elastic components, due to the uneven surface deformation, the larger the cutting amount, the larger the residual stress, grinding residual stress is the largest. Reasonable processing technology and appropriate cutting dosage should be formulated. In the process of heat treatment, the residual stress in the core and the surface is different because of the uneven cooling temperature and the phase transformation of metal materials. The tensile stress is in the core and the compressive stress is in the surface. A tempering process must be used to produce stress in the opposite direction, which is offset with the residual stress to reduce the influence of the residual stress. 4. Resistance strain gauge and strain binder The resistance strain gauge should have the best performance, requiring good sensitivity coefficient stability, small thermal output, mechanical hysteresis and creep, fatigue life up to 108 when strain variable is 1000×10 -- 6, small deviation of resistance value, good uniformity of batch quality, etc. Strain binder should have high bond strength and shear strength. The elastic modulus is large and stable; Good electrical insulation performance; Having the same or similar coefficient of thermal expansion as ...
Sensor is a kind of device that can transform physical or chemical quantities into electrical signals for easy use. The International Electrotechnical Committee (IEC) defines it as: "A sensor is a pre-component in a measurement system that converts input variables into measurable signals".What are the types of sensors in production and life. 1. Light sensor The optical sensor uses the photoconductive effect or photogenerating volt effect of semiconductor. Photogenerating volt effect is detected by the voltage or current generated at the PN junction of the semiconductor as output through light irradiation. Such as photosensitive tube, photosensitive tube and so on. These effects all take advantage of the quantum properties of light. The most common example is light-controlled lighting. 2. Temperature sensor Used to detect the physical effect of temperature, in addition to the use of Seebeck effect thermocouple, usually using Pt, W and other metal and oxygen semiconductor and non-oxide semiconductor, organic semiconductor resistance with temperature changes as a temperature sensor. In addition, there are PN junction current - voltage characteristics with temperature changes, using the Curie temperature near the magnetic properties and dielectric constant changes of the sensor, the use of dielectric constant and piezoelectric constant changes, to detect the resonance frequency changes of the temperature sensor, such as the common air conditioning temperature control. 3. Pressure sensor Most pressure sensors use some kind of piezoresistive effect. Piezoresistive effect means that when pressure is applied to a resistance body, its resistance value will change. This phenomenon is called piezoresistive phenomenon, which is much more obvious than the change of metal resistance, mainly because of the change in the mobility of electrons or holes after compression. More common applications are electronic scales. 4. Magnetic sensor The common effects of magnetic sensors are hall effect and reluctance effect. Using hall effect device is the hall element, it is between on both ends of a semiconductor wafer, with current if the flakes in vertical direction and a magnetic field, the carrier under the action of Laurent force and move along a direction perpendicular to the magnetic field direction, if the electrode is set in the direction, can detect the voltage to the voltage (hall). Typical application such as electric car speed regulation method. 5. Gas sensor A gas sensor is actually a semiconductor gas sensor. Mainly gas adsorption effect. For example, the gas sensor made of semiconductor SnO2 sintering is polycrystalline. When the surface absorbs gas molecules, there will be electron exchange between the gas molecules and the sintered body. The barrier at the grain interface, which controls the movement of carriers, changes. If two electrodes are arranged on the sintered body, the resistance between them will increase and decrease with the adsorption of gas ...
