A cantilever beam load cell consists of an elastic body, strain gauges, and measurement circuitry. Cantilever beam sensors typically employ a single-end fixed configuration, where one end is rigidly fixed while the other end is freely suspended. Unlike parallel beam sensors, the strain gauges for cantilever beam sensors need to be affixed closer to the fixed end, whereas those for parallel beam sensors are attached to the top and bottom surfaces of the two beams. The working principle of load cells can be referenced from the introduction of CP series load cells.

Our company’s CBD series digital cantilever load cell is a digital sensor that comes with a high-precision analog-to-digital conversion module, allowing it to output digital signals rather than analog ones. Compared to analog sensors, digital sensors have the following advantages:

1. Digital signals have stronger interference resistance;

2. They support various compensation functions, such as temperature compensation and load offset compensation;

3. Communication speed is significantly improved compared to analog signals.

The CBD series digital load cells offer a wide measurement range from 220 kg to 4400 kg, with an accuracy class up to C6 level. Additionally, they feature IP68/IP69K protection ratings, providing better protective performance in industrial production environments.

Parallel beam sensors mainly consist of an elastic body, strain gauges, and measurement circuits. The elastic body of parallel beam sensors uses a dual parallel beam structure, typically made from aluminum alloy or stainless steel. When the elastic body deforms under external force, the strain gauges attached to its surface also deform, causing changes in their resistance values. These changes in resistance values are converted into electrical signals through the measurement circuit and then transformed into readable weighing values via an analog-to-digital converter (ADC module). Parallel beam sensors, known for their simple structure, high precision, wide measurement range, and good stability, have become one of the most commonly used types of load sensors in industrial fields, especially suitable for high-precision measurement scenarios.
