The domestic loss-in-weight scale instrument is generally controlled according to the reduction rate of the material weight in the weighing hopper, so as to achieve the purpose of quantitative feeding. Moreover, through fast charging, the feeding time can also be shortened, thereby increasing the The weighing accuracy of the weightless scale and its control accuracy. Therefore, through reasonable use, etc., we can achieve the desired use effect.

domesticWeightless scale instrumentIt is a weighing control instrument developed and produced for dynamic real-time batching equipment. Fully automatic control, continuous batching process does not require manual intervention. It can be widely used in plastics, food, chemical and other industries that require continuous weightless batching control.

Technical parameters of domestic weightless scale instrument:

1. Automatically obtain the maximum flow

2. The display accuracy of the instrument is 1\/100,000

3. Support multi-instrument online proportional continuous and constant speed batching

4. Automatic judgment and alarm for bridge erection

5. Material level automatic control

6. One sensor input, one analog input to control the target flow

7. High-precision dual-channel 16-bit DA analog output, output test and correction function

8. Analog output supports customization

9. RS232\/485 optional serial port, support PROFIBUS bus communication

With the continuous development of technology, the domestic weightless scale instrument adopts advanced analog signals to complete the weighing task. The specific parameters and operating characteristics are as follows: the signal processing inside the weightless scale instrument is a digital signal, but the input is still 420mA, and the control device The digital communication technology is used between the control device and the upper computer. At present, the widely used instruments in the market include DCS system, PLC system and FCS system, etc., and the application characteristics of these three are different.

Secondly, the domestic weightless scale instrument uses the DCS system to carry out specific weighing operations, which is conducive to the guarantee of accuracy. The most critical point of its use lies in the function of communication. It can also be said that the data highway is the backbone of the distributed control system DCS. Its task is to provide a communication network between all parts of the system, so the design of the data highway itself determines the overall flexibility and safety. Today, the DCS system of the weightless scale instrument is gradually moving towards a high-tech, high-level stage.
