БКИ серии регулятор температуры

CHB Series Intelligent Temperature Controllers CHB Series Intelligent Temperature Controllers use computer chip as the main control unit. The controllers have perfectly designed circuit, mature control program, digital PID and self-tuning function, fuzzy control mode etc, which endows the equipments with advantages of high measurement accuracy, correct and stable temperature control, strong anti-interference and simple operation. They are widely used in chemical, ceramic, light, metallurgical, petrochemical and plastic industries as substitution of traditional pointer meter. 1.
