Industrial Usage Thermometer Digital Display Temperature Controller

-Thermal resistance or thermocouple input and measuring range both can be set freely.

--Software adjust zero and full scale, temperature measuring of cold-end alone, amplifier constant-zero, display accuracy is better than 0.5%FS.

--The method of fuzzy theory with the traditional PID make the temperature be controlled quickly and smoothly.

--The method of advanced PID parameter self-tuning saves a third time as compared with ordinary instrument.

--The output signal is optional: relay output, DC12V driver solid state relay, 4-20mA current

--Alarm output: two circuit user-defined alarm output.

1) Upper limit bias alarm: if settting value is 150 °C, when alarm value was been set 2 °C and alarm return difference is 1 °C, then alarm system starts to alarm when temperature rised to (150+2) °C, and stop to alarm when temperature returned to (150+2-1) °C.

2)Lower limit bias alarm: if settting value is 150 °C, when alarm value was been set 2 °C and alarm return difference is 1 °C, then alarm system starts to alarm when temperature returned to (150-2) °C, and stop to alarm when temperature rised to (150-2+1) °C.

3)Upper limit absolute value alarm: if settting value is 150 °C, when alarm value was been set 152 °C and alarm return difference is 1 °C, then alarm system starts to alarm when temperature rised to 152 °C, and stop to alarm when temperature returned to (152-1) °C.

4) Upper limit absolute value alarm: if settting value is 150 °C, when alarm value was been set 100 °C and alarm return difference is 1 °C, then alarm system starts to alarm when temperature rised to 100 °C, and stop to alarm when temperature returned to (100+1) °C.
