Principle
The instrument consists of Thermocouple, photoelectric switch selector, amplifier, A/D converter, monolithic microcomputer, keyboard, display, Communication interface, Data storage device, cold junction compensation and other parts. The photoelectric switch selector selects the corresponding channel signal, amplifies it through the signal amplifier, and then converts the analog signal into a data signal through the AD converter, which is processed by the monolithic microcomputer for data processing. The cold junction compensation circuit performs room temperature measurement to obtain the cold junction temperature value. The measurement signal and the cold junction temperature value are processed by the monolithic microcomputer to obtain the correct Measuring temperature value and display it on the display screen. The keyboard, Communication interface and Data storage allow data to be set up, stored and analyzed, and can also be connected to a computer for Data analysis through the Communication interface.
Applications
Lighting appliances, power tools, household appliances, motors, electric heating appliances, medicine, petroleum, chemical, metallurgy, electric power, R & D institutions, production lines, laboratories, Quality control departments
Steps
1. Connect the Thermocouple Sensor to the corresponding channel
2. Select the display interface through the 7-inch touch screen (such as real-time list, Linear dispersion chart, column chart, etc.)
3. Set the recording interval (HH: MM: SS, adjustable from 1 second to 24 hours)
4. Customize the channel name and Thermocouple type as required
5. Start recording, and the data is automatically stored in the file
6. Export the record file to Excel through U disk or Communication interface
7. Use the built-in analysis function for Linear dispersion analysis, set the X-axis and Y-axis coordinates, translate and zoom in and out Linear dispersion
8. View the alarm list and handle the alarm
Notice
• Ensure that the power supply is within the range of AC85-265V +/- 10% 50Hz/60Hz
• Operating Environment 5~ 40 ℃, 20%~ 80% RH (no condensation)
• The maximum voltage difference between channels is AC/DC 350V to avoid overvoltage use
• Thermocouple type needs to match settings to ensure measurement accuracy
• Record files support up to 64, each file 130,000 group of data, pay attention to storage space
• Make sure the USB stick or PC connection is stable when exporting files
• Relay output can be set with backlash and delay, which need to be adjusted according to the application
• The alarm buzzer can be set to silent, but it needs to be checked regularly that the alarm function is normal
• Modular expansion to ensure that the automatic identification function is normal
