Detailed Description
Model: W279879 Weighing XK3120 Series Display Control System is dedicated to belt weigher, quantitative Feeder (commonly known as mixing balance), and zero gravity scales, spiral scales of measurement control instrumentation, is a machine-control instrument. With my company in a dynamic measurement and weighing ingredients multi-site services and product development manager, adopted advanced microelectronic technology, electromagnetic compatibility (EMC) technology, high-precision A / D converter, Chinese-menu interface. Products with high accuracy, anti-interference capability, performance is stable and reliable, convenient operation and maintenance characteristics. The products are widely used in mining, metallurgy, cement, chemicals, tobacco, and road construction industries in a variety of raw materials and ingredients of the dynamic measurement control system. Weighing principle □ Weighing bridge with the belt weighing sensors detect the weight of the materials, sensors gun belt conveyor speed signals, and signal and send weighing instruments, weighing instrument to receive the speed signal and Weight signals are processed by the cumulative quantity of materials and transient flow. □ configuration characteristics: 0.56 inches of the digital display, an external micro-printer, desktop or disk can be loaded. □ Features : ● 24 △ Σ high-precision A / D converter High-precision, high-speed, low temperature, greatly improved measurement accuracy; ● automatic zero The need for the user operation, automatic calculation and promptly update 0:00; ● automatically correct range Offers pegged yards calibration chain code calibration and in-kind calibration; ● programmable features User-programmable to meet a variety of user requirements instrument; ● selectable analog output Transient flow for the transmission signal, the output signal PID; ● programmable switching output User-programmable output signal switching to provide a variety of information or trigger various auxiliary equipment; ● multi-level password protection To provide different levels of users can change the password protection; ● super anti-jamming capability There belt weigher surrounding noise interference sources, XK3120 made in the design of this full consideration, instrumentation using multiple filtering techniques, input and output photoelectric isolation, resistive and capacitive filtering, transient voltage suppressors, and other overvoltage protection Anti-jamming hardware technology, as well as various digital filtering, data validation and reset the watchdog of software such as anti-jamming measures, with superior resistance noise or other interference capability. ● humane man-machine interface Employ a variety of configurations, users can select various grades in accordance with the configuration; ● adapt to a wide range of power A global industrial power, in AC85-264V voltage used in many countries in the world are able to normal. □ instrument function: ● can show that the total volume, flow, settings, PID output value, speed, weight and other data; ● with manual PID output function can be directly in the panel motor speed regulation; ● 4-20 mA flow settings input; ● 4-20 mA output instantaneous flow; ● accumulated by tons of output pulse form; ● with Kuiliao, overloading, belt deviation, weight, speed, etc. fault alarm messages; ● group can be found on the production; ● control feeder commitment; ● built-in real-time clock and calendar; ● impact of the clock input to the speed control function, in the absence of installing speed sensors or speed sensor damage circumstances, could be replaced by speed sensor, as usual weighing instruments; ● with power protection, even in the case of power failures, instrument parameters guarantee decade not lost; ● RS232/RS485 communication interface with a standard communication protocol is ASCII code and two optional Modbus RTU-can be convenient and DCS (Centralized Control) network operating system, the use of Modbus RTU-standard communications protocols, and easily connect Kingview Monitoring Software , the settings can be entered easily complete remote monitoring, saving labor; ● instrument settings with long-term compensation, the sensor sensitivity signal transmission distance from the length and temperature change; ● can access a variety of measurement speed sensors, such as optical, electromagnetic, 2 (c) line grounding switch; gun position sensor can be installed at its option, can be installed in the back belt, the cylinder axis, the electrical axis ; gun gun round diameter sensor output and the output frequency can be freely chosen, speed sampling magnification can be arbitrary, even in very low speed can be very precise measurement of velocity; ● YHL series can connect large screen display, remote display of total volume and instantaneous.
