The weighing module thus overcomes many shortcomings of traditional analog signals, such as easy interference and attenuation, and greatly improves the reliability of the weighing system. Weighing module has become a necessary device in process control, which has been applied to almost all weighing fields, from the weight measurement of large storage tanks and hoppers and the control of cranes to the mixed distribution, automatic detection in production process and the control of powder feed.
020-34563445The weighed weight or load of the weighing module is placed on the platform of the carrier. Under the action of gravity, the weight is transmitted to the weighing module through the carrier, so that the elastic body of the weighing sensor is deformed, and the bridge of the strain gauge attached to the elastic body is out of balance, and an electrical signal proportional to the weight value is output, which is amplified by a linear amplifier. Then it is converted into a digital signal by A/D, and the weight signal is processed by the microprocessor (CPU) of the weighing instrument, and then the weight data is displayed directly. After the printer is configured, the weighing data can be printed and recorded. If the computer is configured, the weighing data can be input into the computer Weighing system for comprehensive management.
The weighing module is insensitive to the change of the position of the force and the influence of the interference force, and the stress distribution in the elastic strain-sensitive area only changes with the magnitude of the force. The technological properties of the elastic working area are good, including good machining, pasting and sealing installation processes. It has low profile structure, convenient installation and good interchangeability. The low profile structure can enhance the anti-unbalanced load and make the working state stable.
