Load cells are physical devices of variable weight which transform pressure and force into a numerical statistic for engineering and mathematical measurement, according to Thomas Net, a website directory of manufacturers, distributors and service providers of everything from actuators to zirconium. Most often used to identify specifications on industrial equipment, load cells are also essential tools for evaluating stability on machinery, which must be tested on a regular basis.
Strain Gauge Evaluation
The most widely used load cell test is strain gauge evaluation, according to Thomas Net. Strain is measured when the load cell is attached to the deck or base of the machinery being tested. The resulting strain caused by the pressure and tension of the load cell is analyzed as numerical data collected through electronic waves. Strain gauge testing helps engineers determine the amount of stress being forced upon the machinery.
Display Features
Modern load cell monitors provide digital display statistics along with numerical measurements of stress, which also include temperature and voltage-to-frequency comparisons. The amount of stress is determined by a comprehensive calculation of four simultaneous points of load cell pressure. Display features are provided in layman's terms for engineers and laborers to comprehend load cell information.
Safety First
Load cell testing is essential to maintaining the integrity of large structures. Multiple story office or apartment buildings, stadiums or towers are subjected to pressures from inclement weather, material erosion and natural disasters. Load cell testing helps engineers ascertain if structures have lost strength, gone off balance or are vulnerable to collapse. Accurately gauging facility strength and stability helps to ensure the safety and security of people, animals and surrounding properties.
