Blogs Introduction to the relevant knowledge of electronic scales

Electronic scale is a kind of weighing instrument, which is a tool for measuring the mass of an object using Hooke's law or the principle of force lever balance. Electronic scales are mainly composed of three parts: load-bearing system (such as weighing pan, scale body), force transfer system (such as lever transmission system, sensor), and indication system (such as dial, electronic display instrument).

(1) The load-bearing mechanism and force transmission system, namely the weighing platform of the electronic scale, is the system that transmits the weight or force of the object to be weighed to the load cell. It usually includes: the carrier that receives the object to be weighed, the bridge structure, the crane Hang connection parts and limit shock absorption mechanism, etc.

(2) The load cell is a conversion element that converts non-electricity (mass) into electricity. It can convert the weight or force acting on it into a physical quantity that is convenient for measurement (usually a linear relationship) according to a certain functional relationship (usually a linear relationship). Electricity, such as voltage, current or frequency, etc.) output.

(3) Universal display instruments are electronic circuits (including amplifiers, knife D converters, etc.) and indicating parts (such as display, printing, etc.) that process the load cell signal.

(4) The power supply is the high-stability excitation power supply that feeds the load cell measuring bridge, and it can be an AC or DC regulated power supply. Among them, the weighing sensor, display components, power supply and other parts, including the analysis and processing of the weight signal, are all managed by the core component CPU, collectively called the electronic scale controller, which is the center of the electronic scale.
