Communication function

(Optional) RS-485 interface, with local and remote communication functions (requires centralized monitoring software, RS-485/RS-232 converter, requires one COM port and one USB port of the PC); up to 16 devices can be connected simultaneously, and the cumulative cable length is up to 800M

PC software usage environment: IBM PC compatible machine, CPU above PII, memory above 128M, Simplified Chinese windows2000 or Simplified Chinese operating system

Control method

Anti-integral saturation PID

Curve observation

With SRAM with battery protection, it can maintain the set value, measured value and sampling time of the device, and can swipe on the touch screen to observe historical data.

Data collection

1. Curve display output - directly save the curve display interface or any interface required by the customer as a BMP file and transfer it to the U disk.

2. USB function - with a large-capacity U disk, a controller automatically saves the experimental data according to the sampling period. Users can insert the U disk at any time to check the data export and generate CSV format files (non-graph). The sampling period is 8 seconds, 30 seconds, and 1 minute. The maximum storage time is 46 days, 173 days, and 347 days, respectively.

3. Connect the printer (optional) - connect to the industrial micro printer. Set the number of prints according to the time to print the verification date, measured temperature and test humidity.

4. Connect the PC (optional) - Connect the centralized monitoring software to record the test data. The curve is automatically displayed in the PC and directly output to the printer. The PC can be used as a remote end point to realize remote monitoring.
