4. Functionality
The 5B47-J01 module functions as a precision signal conditioner for Type J thermocouples. It accepts the low-level millivolt signal generated by the thermocouple, applies cold-junction compensation to correct for reference junction temperature, linearizes the nonlinear thermocouple response, and amplifies the signal to a standardized 0–5 V output.
Operation Principle:
1. The thermocouple connected to the input terminals generates a voltage proportional to the temperature difference between the measurement junction and the reference junction.
2. The module’s internal circuitry measures the ambient temperature at the input terminals (cold junction) and compensates for it electronically.
3. The thermocouple signal is then amplified and linearized according to the Type J thermocouple curve.
4. The conditioned signal is output as a 0–5 V DC voltage corresponding linearly to 0°C–760°C.
Use Cases and Applications:
- Industrial process monitoring and control
- Laboratory temperature measurement systems
- Data acquisition systems (DAQ)
