In recent years, the instruments in checkweighers are in the development stage of changing from traditional sensors to new types of sensors. The development of MEMS has brought the miniaturization, intelligence, multi-function and reliability of sensors to a new level. The detector is based on microelectronics technology, with built-in microprocessor, test transformer or packaged micro-sensor, microprocessor and related integrated circuits, to achieve digitization, intelligence, networking and systematization.

A checkweigher is actually a device that converts a mass signal into a measurable electrical signal output. Before using the sensor, the actual working environment of the sensor must be considered. This is very important for the correct selection of the load cell. It is related to the sensor's Normal operation, safety and service life, and even the reliability and safety of the entire weighing instrument. There are qualitative differences between the old and new national standards in the basic concepts and evaluation methods of the main technical indicators of the load cell.
