The use of paperless recorders in the field of industrial automation

Paperless recorders in the field of industrial automation, recorder products are mainly used in the field of process parameters such as temperature, pressure, flow, liquid level display, recording and control. With the development of electronic technology, new paperless recorder products show more and more obvious advantages.

(1) No mechanical moving parts, less maintenance during use: As the paper recorder needs the servo drive mechanism to drive the movement of the stylus pen and the recording paper, mechanical aging will occur for a long time, causing paper jams, stylus pens to be adjusted, etc. Problems; and paperless recorder data recorded in the electronic chip and through the LCD display to read through data, so these maintenance problems do not exist.

(2) Data can be transferred to a computer for further data storage and analysis: Historical data stored in the memory chip (without power loss) stored in the paperless recorder can be used with U disk (some companies adopt Floppy disk or CF card, it is a bit troublesome to read the data) Copy the historical data through the USB data port on the instrument, and then use the analysis software provided by the paperless recorder manufacturer to read and analyze the data in the U disk.

(3) Universal input signal function: Due to the advancement of chip technology, the new paperless recorder products have a variety of standard on-site instrument signal direct access, versatile features, such as 0 ~ 5V, 1 ~ 5V, 0 ~ 10mA , 4 ~ 20mA (two-wire system), 4 ~ 20mA (active), Cu50, PT100, resistance (0-400Ω), B, S, K, E, J, T and other signals can be directly connected, software settings You can. Eliminates the need for temperature transmitters, on-site instrument power supplies, and more.

(4) Large-capacity, long-term data recording function: Due to the development of new memory chip technology, large-capacity memory chips are getting smaller and smaller and their capacities are getting larger and larger. This improves the data storage capability of the paperless recorder. It is possible, for example, that our color paperless recorder has an internal storage capacity of 248M and a recording time of up to 10 years (recording interval is once every 4 minutes).

(5) Communication function: Most of the paperless recorder products also have communication functions and can form data communication networks with industrial computers.

(6) Print function: Some paperless recorder products also have a built-in printer driver, which can directly connect external micro-printer printing history or real-time data reports, curves, etc.

(7) Chinese position number, logo: Domestic new paperless recorder products have built-in Chinese character library, which can set Chinese position number, logo, etc.

(8) PID adjustment, alarm, signal transmission and other auxiliary functions In the field of industrial automation, recorder products are mainly used in the field of process parameters such as temperature, pressure, flow, liquid level display, recording and control. With the development of electronic technology, new paperless recorder products show more and more obvious advantages.
