SPECIFICATIONS
INPUT
Thermocouple Type J; Range: 0 to 600 °C (32 to 1112 °F)
Thermocouple Type K; Range -50 to 1000 °C (-58 to 1832 °F)
Thermocouple Type T; Range: -50 to 400 °C (-58 to 752 °F)
Thermocouple Accuracy: 3 °C (5.4 °F)
Pt100; Range: -200 to 530 °C (-328 to 932 °F); α= 0,00385; 3 wires;
PT100 Accuracy: 0.7 °C (1.3 °F); according to IEC-751 standards;
Thermistor NTC, 10 kΩ @ 25 °C; Range: -30 to 105 °C (-22 to 221°F);
Accuracy: 0.6 °C (1.1°F);
Maximum error in the interchangeability of NTC sensors: 0.75 °C (1.35 °F). This error can be eliminated through the offset parameter of the controller.
Note: For the NTC thermistor option, the sensor comes with the controller. Its operating range is limited to -30 to +105 °C (-222 to +221 °F). It has cable of 3 meters in length, and can be extended up to 200 meters.
