By definition, load cell is a type of force transducer.It converts an input mechanical force such as load, weight, tension, compression or pressure into another physical variable, in this case, into an electrical output signal that can be measured, converted and standardized.As the force applied to the sensor increases, the electrical signal changes proportionally. Literature: White    Papers, Guides, Brochures. This white paper explains that modern checkweighers are capable of far more than just weighing and reveals the many advantages they offer manufacturers. That leads to the fact that any other vertical accidentally occurring force in a load cell system has direct impact on the accuracy. In its different configurations, it can also be used for measurements on cantilever beams, platforms, or traction compression control applications. Thank you for visiting www.mt.com. What is load cell calibration? That strain is taken by the strain gauge which changes its resistance into an electrical quantity that can be measured and reported as a weighing result. Weighing is more accurate than radar- or ultrasonic, flowmeters or level sensors for tank or silo inventory control.

The basics of load cell technology is converting a load - which is a force applied to any mass in the earth gravity field – into an electrical signal. An efficient method calibrating larger tanks scales is RapidCal. Calibration is a process that assesses the load cell accuracy to ensure weighing results remain within predefined tolerances. They reach from microgram in micro load cells to several hundred (100) tons in high capacity load cell scales. It covers design calculations, thermal effects, piping connections, designing of support structures and calibration. The mass applies a load enforced by the gravity field, that load stresses the body of the load cell and lead to deformation – strain. Load Cell wiring or cabling is often under estimated on accuracy impact. Other than load cells weigh modules also provide safety functions for coping with wind and seismic loads. Thus, it is crucial to have a very stable excitation source that eliminates effects cause by the power source. Why is product handling expertise now more in demand than ever? Large capacities are used for storage applications.How accurate are load cells?
