What is a tensile testing machine sensor
Category: Industry News
After nearly a decade of introducing, digesting, and absorbing foreign tensile testing machine sensor technology, China's R&D field has expanded from a single variety to include humidity-sensitive, gas-sensitive, voltage-sensitive, force-sensitive, heat-sensitive, light-sensitive, magnetic-sensitive, sound-sensitive, ion-sensitive, radiation-sensitive, and bio-sensitive tensile testing machine sensor types. A certain scale of tensile testing machine sensor production capacity has been formed, and the main product development areas are basically consistent with those abroad. However, the development of basic technologies for product and commercialization in China is seriously lagging behind. Due to the emphasis on the R&D stage of tensile testing machine sensor technology and the relative neglect of the development of basic industrialization, the manufacturing processes and equipment, materials, testing and instruments, and other related supporting common basic technologies are disconnected, which restricts the industrialization process and lags behind international standards. 10-15 years.
There is a lack of independent technological innovation, and technology is repeatedly tracked. Currently, many domestic enterprises use foreign components for processing, and their independent innovation capabilities are very weak, with few independently developed products. Many enterprises even only remain at the level of agency for foreign products, resulting in limited development space. Following the inertia of long-term dependence on foreign technology, domestic tensile testing machine sensor enterprises have created a situation of "strong outside, weak inside" in technology. This has not only lost the market for high-end products, resulting in serious homogeneity, but also directly led to a single variety of products. Many domestic products can only imitate the appearance of others. Even so, due to the low technical level, the sensitivity, accuracy, and reliability of imitation products are unsatisfactory. Below, we will tell you what a tensile testing machine sensor is.
1 Sensitive element. Directly senses the measured ( mass ) and outputs other quantities with a definite relationship to the measured quantity. For example, the elastic body of a resistance strain-type weighing sensor can convert the mass of the measured object into deformation; the elastic body of a capacitive weighing sensor converts the measured mass into displacement. 2 Transducer element. Also known as a sensing element, it converts the output of the sensing element into a signal that is easy to measure. For example, the capacitor of a capacitive weighing sensor converts the displacement of the elastic body into a change in capacitance; the strain gauge ( or strain gauges ) convert the deformation of the elastic body into a change in resistance. Sometimes, some elements have the functions of both sensitive elements and conversion elements. 3 Measuring element. The output of the conversion element is converted into an electrical signal, which provides convenience for further transmission, processing, display, recording, or control. 4 Auxiliary power supply. Provides energy for the electrical signal output of the tensile testing machine sensor. Generally, weighing sensors need an external power supply to work. Therefore, as a product, the power supply requirements need to be specified, but it is not a component of the weighing sensor. Some sensors, such as magnetoelectric speed sensors, can work normally without an auxiliary power supply due to their high output energy. Therefore, not all sensors require an auxiliary power supply.
