　　The principle and application of weighing sensors

　　A weighing sensor is a conversion device used to convert weight or pressure signals into electrical signals. The weighing sensor adopts a metal resistance strain gauge to form a measurement bridge, which utilizes the principle that the metal resistance wire elongates and becomes thinner under tension, and the resistance increases, that is, the effect of the metal resistance changing with the stress (strain, which is the change in size)

　　The construction principle of weighing sensors. Metal resistors have the property of obstructing the flow of current. Generally speaking, the thinner the metal wire, the higher its resistance value. When a metal resistance wire is stretched or contracted by external force, its resistance value will increase or decrease within a certain range. Therefore, when the metal wire (or film) is tightly attached to the object being measured, and the object is stretched or contracted by external force, the metal resistance wire (film) will also expand or contract proportionally, and its resistance value will change accordingly. A weighing sensor is a device that measures weight signals by attaching metal resistance strain gauges to a metal weighing beam.

　　In the entire fixed value packaging control system, the weighing sensor is a key component that affects the measurement accuracy of the electronic scale, and the gyl-3 strain gauge weighing force sensor is selected. Four resistance strain gauges form a full bridge circuit. Under constant bridge pressure u, the sensor output signal is proportional to the gravity acting on the sensor and the bridge voltage supplied to the bridge. Moreover, changes in the bridge voltage u directly affect the measurement accuracy of the electronic scale, so it is required that the bridge voltage be very stable. After amplification, the output of the millivolt level sensor becomes a voltage signal output of 0-10v, which is sent to a v/f converter for a/d conversion. The frequency signal output from its output terminal is added to the counting and input terminal t1 of the microcontroller 8031 timer 1. Timer 0 is used for counting and timing inside the microcomputer, and the timing time of Timer 0 is set by the required A/D conversion resolution.

　　The count value of Timer 1 reflects the measured voltage, which is the weight of the material. At the same time as displaying, the computer also determines the fixed value based on the set value and the measured value. Compare the measured value with the given value, take the difference and provide PID operation. When the weight is insufficient, continue feeding and display the measured value. Once the weight is equal to or greater than the given value, the control interface outputs a control signal to control the external feeding equipment to stop feeding, display the final measurement value, and then issue a response command to indicate that the bag has been loaded and the weighing of the lower bag can be carried out.
