Small long chart paperless recorderCan input signals such as standard current, standard voltage, frequency, millivolts, thermocouples, thermal resistors, etc. It has sensor isolation distribution output, relay alarm output, transmission output, flow accumulation, temperature and pressure compensation, historical data transfer, printing, and remote communication functions. According to user requirements, its data storage capacity can be configured to 256M, which can meet the data storage requirements of any industrial site. Especially through the use of USB drives to retrieve data recorded by instruments, compared with other methods such as IC cards, it has the advantages of large data storage capacity, convenient and reliable use, and is suitable for practical on-site use.
The design function and development of the small long chart paperless recorder maintain universality with the color medium long chart paperless recorder. The basic functions are consistent, the volume is reduced, the cost is lowered, and new technologies such as data space (RAM) expansion paging access management and code space (ROM) expansion switching are used.
Small long chart paperless recorderIt mainly consists of industrial emblem processor, A/D converter, read-only memory ROM, random access memory RAM, display controller, LCD display, keyboard controller, alarm circuit, clock circuit and other parts. Using a single-chip microprocessor as the core Collect and process various data The recorded data can be sent to the random access memory (RAM) for storage Or it can be sent to the liquid display screen for display, or as needed Zoom in or out freely For the convenience of operators to observe the status of the recorded signals. At the same time The recorded signal can be compared with the set upper and lower limit signals, and once it exceeds the limit, an alarm signal will be issued.
The characteristics of the small long chart paperless recorder:
1. No paper, no ink, no mechanical rotating parts No need for daily maintenance. High precision and reliability Good universality and strong functionality.
2. There are various types of input signals that can be used in conjunction with thermocouples, thermal resistors, and various transmitters that can generate standard DC current and voltage signals.
3. It can display trend curves, data, reports, real-time bar charts, etc., and can realize the selection and cyclic display of single channel/multi-channel curves, bar charts, numbers, etc.
4. The input signal can be configured or programmed, and can achieve temperature and pressure compensation, flow integration, and PID control, with alarm function.
5. There are high-capacity chips that can store measurement data And it can be stored in semiconductor memory or floppy disk.
6. The stored data can be processed and analyzed in various ways through the human-machine interface It can also be analyzed and processed using software on a PC High reliability and easy to use Meets the requirements of modern informatization.
