4. Functionality
The MDTPT3401 functions as a temperature signal conditioning module for Pt100 sensors. It converts the resistance change of the Pt100 element, which varies with temperature, into a proportional voltage output. The module’s internal circuitry linearizes the Pt100 response and scales it to a ±5 V analog signal, where each degree Celsius corresponds to 1 mV.
Operating Principle:
- The Pt100 sensor is connected to the module via 2 or 3 wires.
- The module excites the sensor with a precise current source.
- The resulting voltage drop across the Pt100 element is measured and converted into a temperature value.
- The temperature is then linearly mapped to the output voltage range (–5 V to +5 V).
Use Cases and Applications:
- Industrial process monitoring and control
- Laboratory temperature measurement systems
- HVAC and environmental control systems
- Machine and equipment temperature supervision
