There are various types of electric heating furnaces widely used in factories, mines, and research institutions for heat treatment, drying and solidification, temperature experiments, and other constant temperature heating. Electric heating furnaces can be divided into two types: 1. Natural convection furnaces; 2 electric blast furnaces; The temperature control range of the touch screen digital paperless recorder is from room temperature to thousands of degrees. During the temperature control process, it is necessary to record temperature changes at any time, and an effective data recording method is essential. Use a temperature regulator or measuring instrument with communication function to record data in a flash memory card
Choosing a regulator with good performance and communication function is the key to electric heating furnaces. The intelligent temperature regulator improves the temperature control effect, thereby achieving rapid temperature control, shortening the production cycle, saving energy, and improving product quality. Easy to use, with significant effects, it widely replaces traditional temperature regulators, making temperature control more effective and saving energy.
Touch screen digital paperless recorder control function:
The structure of the touch screen digital paperless recorder consists of an upper computer and a lower computer.
1. Upper computer: Touch screen digital paperless recorder, which displays the current temperature, current device position, and current status on the flowchart of the touch screen paperless recorder. It can be switched by touching the button, clicking the start button to start the motor, move the crucible up and down, and open and close the furnace door. Combustion control. Simultaneously record all data on CF cards and USB drives, and print curve reports.
2. Lower computer: The temperature regulator performs programmed PID adjustment based on the measured value and set value, controlling the thyristor to regulate the electric heating furnace, thereby ensuring the stability of the temperature inside the furnace.
Historical curve, data, alarm query: Temperature history screen:
On this screen, you can query the historical temperatures involved in actual control and record the temperature data of each channel separately. The values marked on the vertical axis are temperature values, and the values marked on the horizontal axis are time values. When querying, temperature data before and after time periods can be queried by moving time forward or backward, or by directly inputting time period data after querying historical curves. The alarm history screen records the relevant historical alarm content of the electric furnace. Click on [S] to query in the lower right corner of the function screen. The touch screen displays the current start time. Modify the start time of the query to: year/month/day/hour/minute/second; Change time span: hour/minute/second settings; Click the [Confirm] button, and the system will immediately display historical curves and data reports; Alarm report; Suggest keeping the time span as short as possible to improve data query speed.
4. There are three ways of data processing:
There is a PC graphic reading software available; Micro printer; Upload an Excel spreadsheet;
External CF card for touch screen to store data; Comes standard with a 1GB electronic hard drive. Expandable CF card with 1-4GB storage and recording space; Data can be printed into reports and curves using a micro printer; Alternatively, data can be stored on a CF card and copied to a PC using a card reader to open the data using graphics software; You can also use the serial COM2 port to backup Excel spreadsheet data to the upper computer. CF card: [AL] data packet is an alarm report; The DL packet is a data report; Save data source files by year/month/day/hour. The data saved is encrypted and must be read using dedicated Yudian PC graphics software.
