Weighing module is a new type of weighing component, which consists of load cell, load transfer device and connecting parts, etc. The weighing module solves the weighing error caused by improper installation and the influence on the service life of the load cell, and ensures the accuracy and long-term stability of the load cell.
020-34563445Weighing module is a device that can measure the weight of an object, which is usually composed of a weighing sensor, a signal conditioning circuit, and an AD converter. The function of the weighing module is to convert the heavy star of the object into an electrical signal output, so as to facilitate the processing and control of digital signals.
The principle of the weighing module is to use piezoresistive or strain gauge sensors to measure the weight of the object. When the object is applied to the sensor, the sensor will undergo a small deformation, which will cause the sensor resistance value to change. The weighing module calculates the weight of the object by measuring the change in the resistance value.
The weighing method is composed of a number of weighing sensor signals through the junction box and then connected to become a signal, resistance changes inside the microprocessor, can diagnose itself, each has its own address, the instrument can monitor each sensor output online and intelligent processing, not only greatly improve the reliability of the Weighing system, And it can easily solve some analog sensors difficult to achieve such as sensor online monitoring, off-load detection and other requirements. Coupled with its own unique high-precision high-speed A/D conversion technology, comprehensive sensor digital compensation technology and remote high-speed explosion-proof communication capabilities, the performance is greatly beyond the analog sensor, thereby improving the stability of the system.
