Electronic Scale Load Cell

Next we will explore calibration and test the load cell as a weighing scale.

Electronic scale load cell.

The strain gauge has a resistive and elastic metal foil material that is fixed and attached to the bending parts of the load cell as shown in the figures below. The load cell must also be accurately wired to the hx711 to ensure that the appropriate strain gauge leads are used to approximate the weight given by the load cell. Image courtesy of amazon. At the heart of electronic scales or weighing machines is a sensor called load cell.

As the weight is applied that end of the load cell bends downwards. These sensors sense the force or weight of the items and the electronic circuitry processes the sensors output and displays it on the indicator. Scale is designed with 0 01kg accuracy and switches are used to calibrate digital weight scale. The strain gauge load cell is a transducer device that has an underlying mechanism called a strain gauge.

The mechanical design of the digital scale then applies the force of the weight to one end of a load cell. Mini scale electronic load cell weighing sensor 1 2 3 5 10 50kg 100g yzc 133. When force is exerted on the load cell the structure and resistance of the strain gauges changes and is measured. They are perfect for electronic scales price computing scales electronic platform scales digital scales.

There are several types of strain gauge load cells. Load cells are highly accurate transducers which provide the user with information not generally obtainable by. Under the flat tray of a digital scale you might find for example four slightly raised pegs in the corners that serve to distribute the force of the weight evenly. Parcel post scales electronic balance and all varieties of commercial scales where weight is involved.

Digital weight scale using arduino and hx711 module load cell this project is to design digital weight scale that measures weight up to 10kg. The most common type used in digital scales is the strain gauge load cell. From the resulting data can be easily determined using the equation above. The hx711 is easily wired to the arduino using any two digital or analog pins.

Such load cells are typically available in many rated loads i e maximum loads. In a load cell the resistors are replaced with strain gauges and arranged in alternating tension and compression formation. We use a load cell of 10kg a module that amplifies the output of load cell and an arduino. Manufacture source and repair load cells.

This particular load cell is commonly referred to as a straight bar load cell or a parallel beam load cell. We manufacture source and repair load cells and components for a wide variety of existing industrial weighing equipment. The one utilized in this project is rated for a maximum weight of 10kg or 22 pounds. Hx711 ad module load cell amplifier 50kg weight sensor body scale for arduino.

With the combination of the hx711 it is able to get measurable data out from a load cell and strain gauge.
