Instruments, although the use of computer control systems has squeezed out some of the recorder market, are still widely used in many small and medium-sized devices, and it can be predicted that they will not be completely replaced by computers for a considerable period of time. At present, the widely used mechanical paper recorders have a series of problems, such as large daily maintenance workload, high operating costs, poor reliability, inflexible application, and inability to process and utilize information.
Paper recorder has large maintenance work
Therefore, many paperless recorder manufacturers have been committed to using new technologies to improve the performance of recorders, such as microcomputer technology, thermal head technology, inkjet technology, etc. Since the 1990s, with the development of ultra large scale integrated circuit technology and liquid crystal graphics display technology, major automation instrument manufacturers abroad have begun to develop a new generation of recorders - paperless and note free recorders. Its appearance has aroused great interest from domestic users and instrument manufacturers, and also indicates the arrival of the paperless recording era. The paperless recorder with 8 channels was thus developed.Around 1992, many foreign companies launched Data acquisition recorder, among which the more representative ones were the Datavis A paperless recorder from Hartmann Laon (H&B) in Germany and the paperless recorder from Panny&Giles Teletrend in the UK. Teletrend's paperless recorder 2 has a standard size of 144 × 144mm and comes with a 3.5-inch disk drive that is fully compatible with PCs. It is easy to transfer or save data from the table to the disk, and can store working data from one day to 640 days (depending on the recording interval). It has four channel bar charts, digital display, and medium range trend curve display functions. The working mode of the paperless chart recorder can be selected through software configuration. Its biggest feature is the use of a color oscilloscope tube as the display, which has color display function.
H&B's Datavis A paperless recorder (³) adopts a small 72 × 144mm casing and a monochrome LCD graphic screen with a resolution of 92 × 200 as the display. It allows four channels of standard signal input and also has three major functions: bar chart display, digital display, and historical trend display. Complete configuration and normal operation under German, English or French prompts, with standard communication interfaces.
China paperless recorder is developing fast
The development of paperless chart recorders in China was carried out at about the same time as that in foreign countries. The National Engineering Research Center of Industrial Automation of Zhejiang University took the lead in investing a large amount of manpower and material resources in the development of paperless recorders in the early 1990s, and completed the development work in June 1994. It entered the field trial phase, began mass production in 1995, and put it on the domestic market. 8 channels data recorder has been invented since then.

Wide applications of paperless recorders
The paperless recorder with 8 channels inputs, as a new generation recorder combining microprocessor technology, ultra large capacity storage, and graphic LCD display technology, has very obvious characteristics:
High reliability
Traditional paper recorders always rely on servo drives and transmission mechanisms, making them the instruments with the highest failure rate and the largest maintenance workload among all secondary instruments; The paperless and note free recorder makes the recorder a fully electronic instrument, without any mechanical transmission components inside, and its reliability will be greatly improved.
No need for daily maintenance on 8 channels industrial paperless chart recorder
Ordinary recorders cannot do without paper and pen, which are consumables that need to be replaced frequently, increasing the daily maintenance workload. Paperless recorders with 8 channels inputs completely eliminate paper and pen, making it impossible to replace them, greatly reducing the workload of instrument workers.
Daily operating costs are zero
The daily operating costs of ordinary recorders include two major parts: one is the replacement of paper and pen, which account for a considerable part of the cost, such as the latest inkjet recorder launched in the market, which requires the replacement of two inkjet heads and one box of recording paper per year, totaling about 2000 yuan; The second is the replacement and maintenance of mechanical movable components. And paperless and note taking devices do not require money to replace paper and pens, and the lifespan of electronic components is much longer than that of mechanical movable parts. Within the normal service life, there is no need to spend money to replace their electronic components.
Functional Diversity
This is obvious. As mentioned earlier, the 8 channels paperless chart recorder is a product that combines CPU, ultra large capacity storage, and liquid graphics display technology. It has functions that are unparalleled by ordinary recorders:
a. High resolution bar shaped display function
b. Digital display function with large font size
c. Convenient and highly precise curve recall function
d. Compression and amplification function for displaying curves
e. Extremely friendly configuration interface
f. Create conditions for data reprocessing, processing, and utilization, such as conducting system analysis, modeling, etc
High Performance but with low price cost
Due to its strong functionality and no need for daily operating costs, its comprehensive usage price is much lower than that of ordinary recorders.
Due to its numerous advantages, chartless recorders have attracted great attention from users, and it can be predicted that they will be widely accepted by users in the near future.
