National LED packaging leading enterprise Guoxing Optoelectronics (002449) (002449.SZ) released a performance report on February 24, showing that in 2010 the company achieved revenue of 877 million yuan, an increase of 39.74%; net profit of 147 million yuan, an increase of 28.29 %.
However, due to the intensified competition in the domestic LED packaging industry, the overall gross profit margin of Guoxing Optoelectronics also dropped from 21.18% in 2009 to 19.61%, a decrease of 1.57 percentage points.
Guoxing Optoelectronics Board of Directors said that in 2010, the company's main products SMD LED production continued to expand, operating income increased steadily.
Essentially, a Compression Load Cell is a block that is designed to hold a load at one point to measure the compression. While tension load cells measure the pulling force, compression load cells measure a pushing force along a single axis. Generally, a compression Load Cell is placed beneath the object that needs measuring.
As mentioned previously, the strain gauge in a compression load cell is deformed when a load is applied, and this deformation is used to produce the measurement.
Depending on the application, compression load cells are used to determine any relative changes in resistance. Using the Wheatstone bridge circuit allows these relative changes to be measured with great accuracy, ensuring reliable results.
Compression load cells are generally made of materials that are resistant to rusting and scratches, as the base plate should be free from any deformity in order to provide precise results. A hardened cover is often used on the base plate to ensure this.
Compression load cells are specifically designed for application where space is limited, and they can be built to be extremely compact. They are also ideal for use for extremely high capacity loads â€“ the compression load cells from HBM are available with maximum capacities of up to 50 tons.
These load cells are highly accurate, which is useful in industries where products are sold by weight. Many compression load cells are single point, which are extremely versatile and are able to measure off-centre loads, which is helpful for ensuring accuracy. Compression load cells also offer long-term stability, and this stability and accuracy can be further ensured with regular load cell calibration services offered by companies such as FIBOS.
The ease of measurement with a compression load cell helps to speed up processing and output, reducing the time spent obtaining results and ultimately lowering costs.
