MODWTA75-03/WTA-75-03-03/WTA-75-03 belt weighing integrator BELT WEIGHING INDICATOR weighing monitor MODWTA75-03/WTA-75-03-03/WTA-75-03 belt scale metering controller is a new generation high performance control instrument developed by our company, which focuses on the advantages of domestic and foreign related products, adopts the latest single chip microcomputer technology and various anti-interference measures, and develops a new type of dynamic material metering and control instrument with full Chinese character liquid crystal display. It can be used in various forms of dynamic metering control, such as metering belt scale and quantitative feed belt scale, chain plate scale, spiral cutter scale, disc scale, rotor scale and punching plate Flowmeter, and can also be used for steady flow and material level control of weighing bin. II. Characteristics :: Excellent metering and batching control 1. high precision ∑-△A/D conversion ,1,000,000 internal code, high speed sampling 200 times per second, meet dynamic measurement. 2. two-way (main road, auxiliary road) intelligent PID adjustment output, parameter self-tuning, make the control more reliable. 3.[ instantaneous flow output ],[ running state output] and [cumulative pulse output] functions. 4.[ speed regulation / constant speed] operation mode selection ;[ closed loop / open loop] measurement control mode selection with or without speed sensor. 5.[ scale given] function, can be set online, more practical. 6.[ moisture input] function to automatically deduct moisture from materials for trade settlement. 7. the [data recovery] function, once the parameter is modified by mistake, the "one key" recovery (password is controlled by the administrator). 8. speed automatic calibration, automatic dynamic peeling, weight calibration, physical running material calibration and calibration test function. 9.RS-485 communication interface; optional support DeviceNet、ModBus、ProfiBus and other communication protocols. 10. A distributed batching metering control system is formed by connecting the instrument analog quantity, digital quantity interface or communication interface with the DCS、PLC or upper computer system. 11. The instrument keyboard, external signals (ports) and upper computer communication can be operated in a variety of ways. 12. With belt deviation, skid, motor shutoff, material shutoff and other alarm monitoring, output functions, belt scale monitoring and protection. 13. Material blocking monitoring function, when the occurrence of SCR output control signal directly drive the silo wall vibrator, with the relevant alarm switch output. 14. Software algorithms and hardware design for inverter control enhance system stability and reliability while improving system cost-performance. 15. A wealth of alarm output switches (flow upper limit alarm, flow lower limit alarm, load heavy alarm, load light alarm). :: One weighing sensor is connected to a variety of sensors and can be connected to standard 4~20 mA (0~10) current type output integrated sensors. 1 main speed sensor ,1 auxiliary speed sensor input. :: Super-industrial standard design industrial grade components, wide voltage and wide temperature range for harsh industrial environment.
