paperless recorder

/Paperless recorders are widely used in various industrial sites such as metallurgy, petrochemicals, building materials, paper, food, pharmaceuticals, heat treatment, and water treatment. The recorder records the collected data/computed data based on time in the storage system inside the instrument without consuming any common recording facilities such as paper, pen and ink. The stored data recorded inside the instrument is simulated through calculation and then displayed on the LCD screen/digital Tube. Commonly used LCD screens are widely used for display. The LCD screen can display digital display, bar graph display, curve display, alarm list, etc.
Functional features of paperless recorder
◆Penless and paperless recording, the daily maintenance workload is very small and the operating cost is low
◆The imported inch* dot matrix high-brightness graphic LCD display has clear picture performance Features such as stable colors, wide viewing angles and long service life
◆Using high-speed and high-performance microprocessor, the screen response time is less than seconds, which can realize road signal collection, recording, display and road alarm at the same time
◆Using large-capacity flash memory chip Store historical data and never lose data when power fails
◆ Fully isolated universal input can input multiple signals at the same time without changing the module through software configuration
