In summary, weigh scales are commonly used in various markets including the retail, industrial, food processing, transportation, and laboratory sectors. Most weigh scales use a load cell based around a resistor bridge configuration where the resistors are strain gauges as the sensing element. The different elements in a weigh scale include: the sensor, the analog front end and ADC, the power system, communications, and the user interface. ADI offers a comprehensive portfolio of sigma-delta ADCs for the weigh scale industry along with a wide variety of components that provide coverage for the rest of the signal chain.
