TREX-СН серии термометр

TREX-CH series thermometer 1.easy operating, auto-tuning 3.economic 4.fuzzy control 5.PID control Widely used in refrigeration, food machinery, plastic machinery, washing machinery(automatic control system).Features: High accuracy and easy operation. Self diagnoses sensor abnormal and overstep scale prompts function. Various input types are available, including thermocouple, thermal resistance and linear signal etc.. Various alarm mode combination. Power-free alarm function. Create a new unique AI adjust mode via combining PID arithmetic and fuzzy control theory, which enable the controller to meet a variety of control system requirements. No overshoot, strong resistance to interference.
