NT28B16 can be used to measure temperature with NTC, and it can also be used to measure common resistance value. 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 ohm
Modbus RTU Command Please refer to : '' NT28B16 modbus rtu protocol''
NTC sensor specifications:
Product Name: 5*25mmNTC Waterproof Probe
Total length : 50CM
Resistance value: 10K/20K/50K/100K(optional)
Resistance accuracy: ±1%
Resistance B value: 3950 ± 1%
Temperature range: -20 ° C -125 ° C
Wire size: 2651 26# parallel line temperature 105 °C
Plug model: XH2.54-2P
Note:
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 accurate
