Temperature controller is a measurement device used on temperature control. Thermocouple-type and resistor-type temperature controllers measure temperature electronically, obtaining the temperature change from the sensor and sending the measured data to the electronic processor. The output device will then control the temperature variation within a specific range. Delta’s DT series temperature controller has fast output response, accurate PID parameter auto-tuning, support Modbus communication protocol and is built-in with various output types, allowing different systems to reach a stable control status very quickly. Besides, all series are complied with international installation dimension and CE, UL international safety approvals.
