ESMLS616 Aluminum alloy Supermarket pricing scale load cell sensors for 2 kg 3kg 5kg 7kg 10kg
Working Principle
When an object is placed on the electronic scale's weighing pan, its weight is transmitted to the aluminum alloy elastomer, causing nanometer-level elastic deformation. This drives the strain gauge attached to the stress zone to deform simultaneously, resulting in slight changes in the strain gauge's resistance. The full-bridge circuit converts the resistance change into a millivolt-level voltage signal, which, after being processed by the sensor's built-in signal amplification module and AD converter, outputs a standard signal proportional to the weight (or is directly transmitted to the scale's mainboard to calculate the weight).
Product Features
- Lightweight: Weighs only 1/3 of a stainless steel sensor of the same specifications, suitable for portable electronic scales.
- Low cost: Low raw material and processing costs, cost-effective, suitable for mass production.
- Low elastic hysteresis: Fast deformation recovery, stable accuracy for continuous weighing.
