What is the working principle of load cell?
Resistive load cells work on the principle of piezo-resistivity. When a load/force/stress is applied to the sensor, it changes its resistance. This change in resistance leads to a change in output voltage when a input voltage is applied.
Why is calibration required?
The primary significance of calibration is that it maintains accuracy, standardization and repeatability in measurements, assuring reliable benchmarks and results. Without regular calibration, equipment can fall out of spec, provide inaccurate measurements and threaten quality, safety and equipment longevity.
What is the objective of calibration?
The purpose of calibration is to ensure that a measuring device is accurate, reliable and consistent. Any kind of measurement is used in a decision-making process, so it is essential that the data collected is accurate.
What is scale load cells?
As per dictionary, a load cell is described as a “weight measurement device necessary for electronic scales that display weights in digits.” However, load cell is not restricted to weight measurement in electronic scales. Load cell is a passive transducer or sensor which converts applied force into electrical signals.
What is load cell system?
Load Cell. A load cell is a transducer which converts mechanical energy (tensile and compressive forces) into electrical signals.
What is load cell tester?
Load Cell Simulators / Testers. A load cell simulator is a handy tool during initial setup, particularly of a batching by weight scale. It replaces the load cell (s) in the system allowing the scale technician to simulate various weights that will trigger the outputs setpoints for activating valves, gates, and mixers.
