4. Functionality

The SETPTF Pt100 Foil Sensor operates on the principle of the platinum resistance temperature detector (RTD). The electrical resistance of the platinum element changes predictably with temperature, allowing precise measurement when connected to a compatible temperature transmitter, controller, or data acquisition system.

- Working Principle:
The platinum element’s resistance increases linearly with temperature. The measurement circuit detects this change and converts it into a temperature reading based on the standardized Pt100 resistance-temperature relationship.

- Use Cases and Applications:
- Surface temperature measurement on machinery, pipes, or components
- Laboratory temperature monitoring and calibration setups
- Environmental testing chambers and climatic control systems
- Industrial process control and automation systems
- Electronics and semiconductor equipment temperature regulation
- Research and development applications requiring high accuracy and repeatability

- Compatibility:
The sensor is compatible with all standard Pt100 measurement devices, including:
- Temperature transmitters (analog or digital)
- PLC input modules with RTD support
- Data loggers and measurement systems
- Laboratory thermometers and calibration instruments
- Industrial controllers and monitoring systems
