Input type: 2/3/4 wire PT100 or tungsten rhenium/B/R/S/N/K/J/T/E thermocouple

Output mode: 2-wire system 4~20mA/HART5 current loop

Output resolution: 1uA

Data update cycle: 1.5 seconds - thermocouple 1 second -2/4 wire heating resistor 1.5 seconds -3 wire heating resistor

Thermocouple cold junction compensation accuracy (AT25 ℃): ± 0.2 ℃ (maximum)

Operating environment: -25~70 ℃~90% relative humidity

Special function: Can be matched with sensors to achieve ultra-high precision measurement.

When the thermocouple is input, an external compensation element can be connected to achieve real-time compensation.

Electrical isolation: Input output isolation voltage 1000VDC

Power supply: 12~42VDC

Accuracy (AT25 ℃ maximum):

Note 2: The total accuracy of the transmitter is: analog-to-digital conversion accuracy+analog-to-digital conversion accuracy. Please refer to the previous section on "About Accuracy" for the calculation method

Overall accuracy after using sensor matching function (transmitter+sensor)

Note 1: The sensors listed in the table are the most commonly used, stable, and representative sensors for various temperature ranges.

Note 2: The thermocouple matching function is a patented technology that needs to be completed before leaving the factory.

Note 3: The accuracy of the thermocouples in the table already includes the cold junction compensation accuracy and does not require additional stacking.

Note 4: Any incorrect or inappropriate calibration operation may to some extent compromise the accuracy listed in this table.
