The operation of an electronic balance can be divided into two parts for understanding. The first is the detection part and the second is the processing part. The sensing part essentially contains a collection of sensors that measure the weight and convert it into electrical form for processing. The process part then takes this signal and displays it on the LCD for a reading. The sensors used for the measurement are known as load cells.

A load cell is basically a transducer (a device that converts a form of energy into another form) that converts a force (the weight in this case) into an electrical signal. The load cell consists of a set of extensometers that deform after the application of a pressure (deformation) on them. This deformation is measured as an electrical signal to be suitable for processing.

Due to the fact that the applied deformation changes the electrical resistance of the wire, a load cell usually consists of 4 deformation meters that are connected as a wheat stone bridge.

A collective output of the 4 strain gauges is obtained, which is in the order of a few millivolts. The arrangement on a weighing scale is such that the object placed on the platform exerts force on the load cells carefully placed underneath it. These transducers generate an electrical signal that is amplified by using a high quality signal amplifier to make it suitable in the back sections of electronics in the device.

This signal after amplification is taken by the processing part which converts the analog voltage into a digital form with the aid of a precision analog-to-digital converter which is then displayed in the digital readout.

This part of digital processing and reading is handled by using a microprocessor control unit (MCU) that can perform other necessary operations based on the design need. These operations can be maintaining some statistical data, setting zero, interfacing to a PC system, etc.

Care is taken to calibrate these devices before use. This is done due to the uniqueness of the components that are used in them. This is an important step without which the device provides an incorrect reading.
