　　0.3kg single point packaging weighing sensor supply detailed instructions

　　With the advancement of technology, electronic scales made from weighing sensors have been widely used in various industries, achieving fast and accurate weighing of materials. Especially with the emergence of microprocessors and the continuous improvement of industrial production process automation, weighing sensors have become a necessary device in process control. In the past, they were used for weight measurement of large tanks, hoppers, crane scales, car scales, and other weighing control that could not be weighed, as well as in batching systems for mixing and distributing multiple raw materials, automatic detection in production processes, and powder feeding control. Now, weighing sensors are almost used in all weighing fields.

　　Traditionally, load sensors are a collective term for weighing sensors and force sensors, used to evaluate their metrological characteristics based on individual parameters. The old national standard combines the two types of sensors, "weighing" and "force measuring", which have completely different application objects and environmental conditions, without distinguishing between testing and evaluation methods. The old national standard has a total of 21 indicators, all of which are tested at room temperature; The accuracy level of the weighing sensor can be determined by using the errors in six indicators: nonlinearity, hysteresis error, repeatability error, creep, zero temperature additional error, and rated output temperature additional error, which are 0.02, 0.03, and 0.05, respectively. .. 1.0 represents.

　　The principle of a weighing sensor is to convert the gravity on the measured object into a measurable output signal in a certain proportion. Considering the impact of gravity acceleration and air buoyancy on conversion in different usage locations, the performance indicators of weighing sensors mainly include linear error, hysteresis error, repeatability error, creep, zero temperature characteristics, and sensitivity temperature characteristics. In various weighing instruments and quality measurement systems.

　　Usually, the comprehensive error is used to bring about the accuracy of the comprehensive control sensor, and the comprehensive error band is linked to the weighing instrument error band in order to select the weighing sensor corresponding to a certain accuracy weighing instrument. The International Organization for Legal Metrology (OIML) stipulates that the error band of sensors accounts for 70% of the error band of weighing instruments. The total sum of linear errors, hysteresis errors, and errors caused by the influence of temperature on sensitivity within the specified temperature range of weighing sensors cannot exceed the error band. This allows sensor manufacturers to adjust the various components that make up the total measurement error, thus achieving the desired accuracy.

　　The principle of the shear beam weighing sensor is that after the elastic body is subjected to force, it needs to measure not only its normal stress, but also the shear stress caused by the shear force. However, the shear stress itself cannot be measured. It can only occur from the principal stress perpendicular to the central axis of the I-beam at a 45 "angle, that is, from the tensile stress and compressive stress caused by the shear stress. Therefore, four strain gauges are attached to both sides of the web plate of the I-beam at a 45" angle perpendicular to the central axis.
