The electronic scale comes with an RS-485 (MODBUS-RTU) interface, while the serial communication port of the PC is an RS-232C interface, and the two need to communicate with each other through the SC-09 adapter cable. Electronic scales use the RS-232C standard to transmit signals using the voltage difference between the signal line and the common ground, a unidirectional transmission method; the RS-485 standard uses the voltage difference between the signals of the transmission line to transmit, a differential transmission method. the SC-09 cable realizes the conversion between these two different signal transmission methods.

Explosion-proof floor scale is weighed or loaded on the scale platform, under the action of gravity, the scale platform will gravity transfer to the load cell, resulting in deformation of the elastomer attached to the load cell, then the elastomer strain beam on the strain resistor and the bridge circuit to lose equilibrium, the output is proportional to the weight value of the electrical signals, the linear amplifier will amplify the signals, and then converted to digital signals by the A/D conversion of the weight instrumentation within the microprocessor to process the weight signal and directly display the number of weight. The microprocessor in the weighing instrument processes the weight signal and displays the weight directly. With the configuration of a printer, the weighing data can be printed; with the configuration of a computer, the weighing data can be directly input into the weighing management system for comprehensive management.

Explosion-proof floor scale explosion-proof grade ExibllCT4/5 ExiaIICT6, welding using carbon dioxide bonded welding continuous weld, cavity fully sealed, the overall surface chemical process. The standard structure of the floor scale, with four sets of adjustable feet, easy to install. Four high-precision and high-strength sensors with 200% overload resistance (made of alloy steel, superior performance and strong impact resistance). Waterproof junction box with high-precision potentiometer. Zero tracking range, zero setting (power on/manual) range, can be set separately.

Explosion-proof weighbridge is mainly a weighing instrument, PLC as an auxiliary control system, computer human-machine interface to display the proportioning parameters (formula) and monitoring and recording of real-time data, weighing instrument according to the set formula to open the weighing valve of the electronic scales, according to the weighing of the fast and slow with the amount of lead time, the weighing instrument detects the weighing of weighing scales to reach the set value, it will be subtracted from the amount of lead time, then close the feed valve. The advance amount can be corrected by human or automatically, so that the weighing instrument can control the electronic scale to reach the set target value every time.

Explosion-proof weighbridge consists of three basic units: weighing platform, load cell, and weighing instrument; the load cell part includes weighing instrument, weighing platform and signal cable. It adopts RS485 interface to communicate with digital load cell, and it can be adjusted manually/automatically for bias load (four-corner adjustment), address and read data of single sensor automatically, and modify the sensor number on the spot automatically. It can realize the processing of data, such as: display, calibration, sending, storage, printing and other functions.

Explosion-proof weighbridge will weigh objects placed on the load-bearing scales, there will be a certain gravity on top of the load-bearing scales, by the scales will be subjected to the distribution of force transmission to the various load cells, in the sensors, the original gravity signal through the deformation of the strain gauges of the force is transformed into an electronic signal, and then drive the electronic signals to the junction box for the organization of the convergence of the weighing instrument through the collection and processing of specific weighing information, after which the weighing value can be displayed. The weighing information is collected and processed by the weighing instrument, after which the weighing value can be displayed. In addition, the weight indicator can be connected with the computer, and the data information can be sorted out by the tool software, which is convenient for users to analyze the data and store the relevant work.
