To achieve networked production management, the explosion-proof electronic scale needs to carry out structural stratification, including management layer, control layer, and equipment layer. The central switch is connected to the control network at the next level 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 instrument, 1/0 module and fieldbus, etc. The acquisition and conversion of various signals are completed by weighing instrument and 1/0 module, and the controller realizes the processing of logic control loop. The control mode after the weighing instrument is used as the core of the entire control system.
020-34563445Explosion-proof Electronic scales are based on the traditional resistance strain sensors, combined with modern microelectronics technology, micro-computer technology integration and the development of a new type of electronic weighing technology, resistance strain gage load cell, by the base of four weighing elastomers constitute the main body of the sensor, in the elastomers on the axial adhesive resistance strain gages perpendicular to each other, when the sensor is subjected to pressure elastomers for a slight deformation, the strain gages affixed to the top, the elastomers are deformed, the elastomers are deformed. When the sensor is pressurized, the elastomer deforms slightly, and the strain gauges pasted on it deform slightly.
Explosion-proof electronic scales to achieve networked production management, the need for structural layering, including management, control layer, equipment layer. Management (composed of various departments such as production scheduling, material management, financial management, chief engineer, general manager, etc.) can be realized through the central switch to connect with the next level of the control network, so as to monitor the entire control system, extraction of production data, analysis reports. Control layer (composed of engineers, operators) can realize the programming of the entire control system, data analysis and storage; equipment layer (production site), including weighing instruments, 1 / 0 modules and fieldbus, etc., a variety of signal acquisition, conversion by the weighing instruments and 1 / 0 modules to complete the controller to achieve the logic of the control loop processing, the use of the instrument after the control mode as the control system. The control mode after using the weighing instrument is the core of the whole control system.
