Recently, Hongrun Instruments has launched several new touch-type paperless recorders. The product series released this time includes “NHR-8700C Series 32-channel touch color paperless recorderâ€, “NHR-8200C series touch intelligent controllerâ€, “NHR-8300C series 8-channel touch adjustment paperless†Recorder, "NHR-8300C Series 8-Channel Touch Thermostat" and "NHR-8600C Series 8-Channel Touch Color Flow Paperless Recorder".
From the function point of view, the touch-type paperless recorder series launched this time has the following technical features:
1. Adopt new large-scale integrated circuit, international famous brand components and new switching power supply design; adopt reliable protection and strong anti-interference design for input, output, power supply and signal.
2, the overall appearance of the streamlined design, small and light, changing the cumbersome shortcomings of the old-fashioned recorder. The rear cover signal terminal adopts the German Phoenix 5.08 pitch plug-in terminal.
3, product dimensions 185 * 154 * 156mm, opening size 138 * 138 * 156mm; 7-inch imported 800 * 480 dot matrix TFT high-brightness color graphics LCD display, LED backlight, clear picture, wide viewing angle. With a 7-inch 800*480 dot matrix four-wire resistive touch screen, the touch is good.
4, using high-speed, high-performance 32-bit ARM microprocessor, built-in embedded operating system, the screen response time is less than 0.3 seconds.
5, large-capacity FLASH flash memory chip storage historical data, power loss will never lose data; every 6 sets of curve display can be freely combined, custom curve color, rich bar graph display, built-in GB2312 second-level Chinese character font, support Chinese character pinyin input , Chinese character number, unit custom combination input.
6, with USB data transfer function, support USB2.0 format interface dump and backup history, support FAT / FAT32 file system type, Windows can identify history files.
7, support standard MODBUS RTU protocol RS485/RS232 communication mode, support MODBUS
TCP/IP protocol Ethernet output, support iFIX, KingView, MCGS, PCAuto and other popular professional configuration software; can be connected to a micro printer, you can choose to manually print data, curves, automatic timing print data, to meet the needs of users on-site printing.
8. It can realize 12-channel switch quantity alarm output or 12-channel analog quantity change output, and the combined quantity of switch quantity and analog quantity output ≤12.
At the same time, for the different types of recorders introduced this time, they also have the following characteristics:
1. Intelligent controller - powerful software, flexible setting method, can realize artificial intelligence control, cascade control, ratio control, valve position control, heating / cooling control, combustion control, double impulse control, three impulse control, Digital input/output control.
2, regulator / thermostat - with real artificial intelligence calculations, no manual tuning parameters, temperature control accuracy of 0.1 ° C, no overshoot, undershoot, reaching the international advanced level, can be applied to industrial furnaces, electric furnaces, ovens , testing equipment, shoe machinery, injection molding machinery, packaging machinery, food machinery, printing machinery and other industries.
3, flow meter - using high-speed, high-performance 32-bit ARM microprocessor, built-in embedded operating system, screen response time is less than 0.3 seconds, instantaneous flow and cumulative flow calculation accuracy of 0.07 ‰, the overall accuracy of 0.2% FS. It has 8 sets of independent flow accumulating functions. The unique software password lock of the flow meter ensures the user's configuration safety; it has the power-down recording function to prevent power-off and stealing steam; the steam metering adopts the automatic judgment of saturation to overheating, which can be changed according to the nature of steam. Realize the automatic compensation of density; provide the function of reporting the report, class report, daily report and monthly report when the accumulated flow rate; the compensation model follows the industry standard of flow measurement.
Single substance is silvery white shiny metal, high hardness, high melting point, normal temperature is not eroded by air, chemical properties are relatively stable. Mainly used to manufacture filament and high speed cutting alloy steel, superhard mold, also used in optical instruments, chemical instruments. China is the world's largest reservoir of tungsten.
