### 4. Functionality

The SETPt100/1615 operates on the principle of the temperature-dependent resistance of platinum. As temperature increases, the electrical resistance of the platinum element rises in a predictable, nearly linear manner. This resistance change is measured by a connected instrument (such as a temperature transmitter, controller, or data acquisition system) and converted into a temperature reading.

Working Principle:
- The platinum sensing element is embedded within a ceramic tube that provides both mechanical support and electrical insulation.
- The sensor is connected via fine platinum or nickel leads to external circuitry.
- The measurement system applies a small, controlled current through the element and measures the resulting voltage drop.
- Using the standardized resistance-temperature relationship defined by DIN IEC 751, the system calculates the corresponding temperature.

Use Cases and Applications:
- Industrial process monitoring and control systems
- Laboratory temperature measurement setups
- Calibration and reference temperature sensors
- HVAC and building automation systems
- Environmental monitoring and test chambers
- Embedded temperature sensing in machinery and equipment
- Integration into thermowells, probes, or sensor assemblies for custom applications

Compatibility:
- Compatible with all Pt100 measurement circuits (2-, 3-, or 4-wire configurations).
- Works with temperature transmitters, PLC analog input modules, and digital thermometers supporting Pt100 input.
- Can be integrated into custom probe housings or sensor assemblies for specific industrial or laboratory applications.
