Different versions have different measurement ranges.10K version: 1K ohm-100K ohm;20K version: 2K ohm-200K ohm;50K version: 5K ohm-500K ohm;100K version: 10K ohm-1000K ohmModbus RTU Command Please refer to : '' NT28B16 modbus rtu protocol''NTC sensor specifications:Product Name: 5*25mmNTC Waterproof ProbeTotal length : 50CMResistance value: 10K/20K/50K/100K(optional)Resistance accuracy: ±1%Resistance B value: 3950 ± 1%Temperature range: -20 ° C -125 ° CWire size: 2651 26# parallel line temperature 105 °CPlug model: XH2.54-2PNote:1 This module does not have an NTC sensor. The NTC sensor needs to be purchased separately (10K/20K/50K/100K B3950 1%);The module's measured resistance value is 1%, and the theoretical temperature range is -273s~200°C. The final temperature measurement accuracy and temperature range are determined by NTC thermistor.2 There are four different versions, be sure to use the corresponding sensor (10K/20K/50K/100K B3950 1%), otherwise the temperature will not be accurateRS485 bus wiring diagram:
