Digital temperature controller
Summary
XMT digital temperature controller uses nowadays the most advanced monolithic microcomputer as mainframe,reduce peripheral assembly,and improve the reliabilityIt adopts the control method of vague theory combined with traditional PID control, and make the control process with the advantage of rapid responsesmall overshoothigh steady state precision. It is intelligence temperature controller with the function of high performancehigh reliabilitycomplete input,its function is suitable to all the occasion needed temperature measurement and control,also be compatible with other industrial parameter measurement and control.
It adopts modular structure,further improve overall performanceThe meter is operated with 4-keys,dual row 4-LED display for displaying the measurement value and set value or measurement value and output value, with manual /automatic switch and setting itself functionwith characteristic of small volumelow power consumptionconvenient operationsteady and reliable of runningThey are now widely used for the automatic control system over the area of machinery, chemical, ceramics, light industry, metallurgy, petrifaction, heat treatment industry.
