4. Functionality
The SETPt100/2815 operates on the principle of the temperature-dependent electrical resistance of platinum. As temperature increases, the resistance of the platinum element rises in a predictable, nearly linear manner. The ceramic tube serves as both a mechanical support and an electrical insulator, ensuring that the platinum wire or thin-film element remains stable and isolated from external conductive materials.

Use Cases and Applications:
- Industrial Process Control: Integration into temperature probes for monitoring process fluids, gases, or surfaces.
- Laboratory Measurement Systems: Used in precision temperature calibration setups or reference sensors.
- HVAC and Environmental Monitoring: Embedded in air or surface temperature sensors for climate control systems.
- Automotive and Aerospace Testing: Suitable for component temperature monitoring in controlled environments.
- Scientific Instrumentation: Incorporated into analytical instruments requiring stable and accurate temperature feedback.

Compatibility:
The SETPt100/2815 is compatible with all standard Pt100 measurement circuits, including 2-wire, 3-wire, and 4-wire configurations, depending on the assembly. It can be connected to temperature transmitters, PLC input modules, digital thermometers, or data acquisition systems that support Pt100 RTDs per IEC 60751.
