Description

Technical Field

[0001] The utility model relates to the technical field of weighing sensors, in particular to a steel cantilever beam type weighing sensor. Background Technique

[0002] With the rapid development of social economy, the application range of weighing sensors is getting wider and wider. A weighing sensor is actually a device that converts a mass signal into a measurable electrical signal output through a certain detection circuit. Among them, the resistance strain type is the most widely used according to the conversion method. The principle of the resistance strain type weighing sensor is that when an elastic body undergoes elastic deformation under the action of an external force, the resistance strain gauges pasted on its surface also undergo deformation accordingly. After the resistance strain gauges are deformed, their resistance values will change with the change of their shapes, and then through a corresponding measurement circuit, this resistance change is converted into an electrical signal, thus completing the process of converting the external force into an electrical signal.
