The pole explosion-proof Electronic scale is a new type of electronic weighing technology developed by integrating modern microelectronics and microcomputer technology on the basis of traditional resistance strain sensors The resistance strain gauge weighing sensor consists of a base with four weighing elastic bodies forming the sensor body. Resistance strain gauges are attached to the elastic bodies along the axial direction and perpendicular to each other. When the sensor is subjected to pressure, the elastic bodies undergo slight deformation, and the strain gauges attached to them also undergo slight deformation. The implementation of networked production management for explosion-proof electronic scales requires structural layering, including management layer, control layer, and equipment layer. The management layer (composed of various departments of the enterprise such as production scheduling, material management, financial management, chief engineer, general manager, etc.) can be connected to the next level control network through a central switch to monitor the entire control system, extract production data, and analyze reports. The control layer (composed of engineers and operators) can realize the programming, data analysis, and storage of the entire control system; The equipment layer (production site) includes weighing instruments, 1/0 modules, and fieldbus. The collection and conversion of various signals are completed by the weighing instruments and 1/0 modules, while the controller implements the processing of the logic control loop. The control mode after using the weighing instrument is the core of the entire control system.

The weighing scale adopts a scale body, which is vertically fixed with support rods. The end of the support rod far away from the scale body is fixedly installed with a weighing instrument, and the bottom of the scale body is equipped with a support mechanism; A circular level is fixedly installed on one side of the upper part of the scale body, and the support mechanism adopts four weighing sensors evenly distributed along the circumference of the bottom of the scale body. The weighing sensors are all installed at the lower part of the scale body, with expansion and contraction parts freely penetrating the scale body and support parts located at the bottom of the scale body. The connection end and the expansion and contraction end are fixedly connected to the operating part, and the expansion and contraction end is rotatably connected to the support part. The expansion and contraction end is threaded to the connection end and the scale body; The operating component drives the connecting end to rotate, so that the telescopic end drives the supporting component to move in the vertical direction. There are four stepped holes uniformly arranged along the circumference of the scale body, each of which is vertically arranged. The upper end aperture of each stepped hole is smaller than the lower end aperture, and four expansion members are correspondingly set in each of the four stepped holes. There are threads on the inner wall of the large diameter section of each step hole of the weighing scale, and each expansion piece is equipped with a vertical rotating screw set in the corresponding step hole and a sleeve set on the screw. The upper end of the screw is fixedly connected to the operating part, and the sleeve is connected to the screw thread. The outer wall of the sleeve is equipped with threads and connected to the large diameter section of the corresponding step hole. After the sleeve passes through the step hole, it is connected to the supporting part for rotation.
