Explosion-proof weighing module can reduce the influence of "static uncertainty" of multi-fulcrum balance of weighing platform by adjusting the stress consistency of sensors, and ensure the stability of weighing platform support, so as to ensure that the bearing capacity of the center of gravity of weighing platform does not deviate, and achieve the accuracy of weighing instrument and relevant metering performance requirements. The weighing module has been compensated in many ways, including output sensitivity compensation.

The working principle of weighing module and the way of strain gauge bridge assembly, the data acquisition system consists of lower computer hardware and upper computer software, the software adopts LabVIEW programming technology, the weighing module obtains the radial pressure on the tilting table, the strain gauge under the tilting table generates strain due to the force, the lower computer obtains data signals, and through the serial communication module, the lower computer and the upper computer data acquisition system transmit instructions and data and process the collected signals. The information is transmitted to users by the upper computer panel. This system has the functions of data acquisition and processing, real-time data display and storage, post-processing of data and monitoring of working temperature.

The weighing module is a multi-channel weighing sensor. The sensors can meet the measurement requirements of different ranges by adjusting the distance between them. Its main function is to obtain the radial pressure of the table, realize the conversion of the local strain of the weighing module to the electrical signal, and then collect and process the electrical signal by using the data acquisition system.

The weighing sensor uses the compensation network based on radial basis function neural network to complete the nonlinear error compensation of the sensor; In the lower limit region, a digital filter is used to complete the nonlinear error compensation. In the middle area, the weighing sensor does not compensate, and at the same time, the selection of subsection compensation is completed by using the adaptive selection network. The piecewise compensation model of nonlinear error is established to obtain good compensation effect.

Weighing sensor is a kind of mass (weight) measurement method that converts mass (weight) into electricity through the stressed structure. The output electric quantity signal and the input quality (weight) signal have a single value linear correspondence; It has the required accuracy and high sensitivity; It has good frequency response characteristics and less inertia; Little influence on the state of the weighed object; Able to work in poor environmental conditions; Good stability, reliability and long service life.

The anti-roll weighing sensor is accumulated through the junction box and transmitted to the weighing instrument, which displays the weight of the material in the current weighing in real time through A/D conversion. The displayed weight data is transmitted to PLC through serial communication, and the PLC compares the collected weight of the weighing module with the weight set in the touch screen (or computer) of the electronic scale to control the action of the whole reaction kettle. It adopts high-performance configuration software, has a complete Chinese interface, and has real-time data display, flow and temperature control curves, alarm and operation records, complete production reports and other management functions.

The weighing module takes the single chip microcomputer as the CPU of the system. The external circuit needs display circuit, keyboard input, power supply, communication interface, sensor and alarm. The sensing element is made of piezoelectric material, and the piezoelectric effect of charge is generated on the surface of the piezoelectric material after being stressed. This charge is amplified and transformed by charge amplifier and measuring circuit, and then it becomes the electric output proportional to the external force. Piezoelectric sensors are used to measure force and non-electric physical quantities that can be converted into force.

In order to realize the static weighing measurement of large containers and hoppers in industrial environment, weighing module integrates weighing sensor, load transmission device, limit and overload prevention, and can be easily connected with various mechanical equipment. On the basis of traditional resistance strain sensor, combined with modern microelectronics technology and microcomputer technology, control functions are added, including weight display, quantitative feeding, unloading, field equipment control, alarm signal display, formula setting and process monitoring.

Stainless steel weighing module is also a detection device, which can sense the measured information and transform the sensed information into electrical signals or other required forms of information output according to certain rules, so as to meet the requirements of information transmission, processing, storage, display, recording and control, and is usually composed of sensitive elements and conversion elements. Among them, the sensitive element refers to the item that can be directly sensed in the sensor, and the conversion part refers to the part of the sensor that can convert the output of the sensitive element into an electrical signal suitable for transmission and measurement.
