4. Functionality
The MDTPT360x functions as a temperature signal conditioning module. It accepts input from a Pt500 or Pt1000 resistance temperature detector, measures the resistance corresponding to the sensed temperature, and converts it into a standardized analog voltage output of ±5 V.
Operating Principle:
1. The connected RTD sensor changes resistance with temperature.
2. The module’s internal circuitry excites the RTD with a constant current source.
3. The resulting voltage drop across the RTD is measured and converted into a temperature value using a precise linearization algorithm.
4. The temperature value is then scaled to a ±5 V analog output signal, where 0 V typically corresponds to the midpoint of the configured temperature range.
Use Cases and Applications:
- Industrial process control and monitoring
- HVAC and building automation systems
- Laboratory instrumentation and test benches
- Environmental monitoring and climate chambers
- Machine temperature supervision and predictive maintenance
- Integration with PLCs, DCS, or SCADA systems for temperature feedback loops
