When the weighing module is used, the technical and economic indicators such as its structural form and measurement characteristics should be correctly selected according to the selection principle to achieve the best performance-price ratio. After the weighing instrument is installed, it needs to be adjusted by sections and randomly. One of the main tasks is to adjust the load distribution of multiple weighing modules, that is, to adjust the stress consistency of sensors.
020-34563445Weighing modules are a method of mass (weight) measurement that converts mass (weight) into electricity by means of a force structure. The output electric quantity signal and the input mass (weight) signal correspond linearly to a single value; have the required accuracy and high sensitivity; have better frequency response characteristics and less inertia; have little influence on the state of the weighed object; can work under poor environmental conditions; have good stability, reliability and long life.
The output voltage signal of the weighing module is accumulated and transmitted to the weighing instrument through the junction box, the weighing instrument displays the weight of the material in the hopper in real time through A/D conversion, and the weighing instrument transmits the displayed weight data to the Weighing system through the serial communication, the weighing system compares the collected weight of the indicator with the weight set by the touch screen (or the computer), and then controls the whole action of the reaction tank weighing. The computer can dynamically display the working status of the kettle dosage, print the weighing data in real time and store the historical data records, which is convenient for users to monitor the working status of the kettle weighing and find the historical data.
The weighing module sends weighing data to the upper computer, adopts high-performance configuration software, develops monitoring program with reliable operation, easy to learn, practical and stable, with full Chinese interface, real-time data display, weight and temperature control curves, alarms and operation records, as well as complete production reports and other management functions, and embeds the ingredient intelligent automatic control module. The upper industrial control computer serves as the human-machine interface.
