What is the difference between a weighing sensor and an electronic scale?
The differences between weighing sensors and electronic scales are as follows:
Definition:
A weighing sensor is a device that converts gravitational force into an electrical signal.
An electronic scale is a weighing instrument used to measure the mass of objects.
Composition:
A weighing sensor typically consists of resistance strain gauges, measuring circuits, and structural components.
An electronic scale primarily comprises a load-bearing system, a force transmission and conversion system, and an indication system.
Principle:
A weighing sensor operates based on mechanical balance principles, converting the force acting on a force-sensitive element into an electrical signal. The millivolt signal output from the sensor is then isolated, amplified, and converted into a standard DC signal.
An electronic scale measures the mass of an object using Hooke's law or the principle of force lever balance.
