4. Functionality
The Pt100Sim26 functions as a precision resistance substitution device that emulates the electrical characteristics of a Pt100 RTD sensor. Each of the 26 selectable positions corresponds to a specific resistance value that matches the resistance of a Pt100 sensor at a defined temperature point (e.g., 0°C = 100.00 Ω, 100°C = 138.50 Ω, etc.).
Operation Principle:
- The user selects one of the 26 preset resistance values via a rotary switch or selector mechanism.
- The selected resistor network is connected to the output terminals, providing a stable and precise resistance equivalent to the Pt100 sensor at that temperature.
- The connected measurement device (e.g., temperature transmitter, indicator, or controller) interprets this resistance as a temperature input, allowing calibration or verification of its measurement accuracy.
Use Cases and Applications:
- Calibration of temperature transmitters, indicators, and controllers.
- Verification of measurement channels in process control systems.
