Considerations
Temperature Range: Some sensors may have a limited operating temperature range (e.g., 0–85°C), which may not be suitable for all environments.
Medium Compatibility: Ensure the sensor material is compatible with the fluid or gas being measured to prevent corrosion or damage.
Accuracy Requirements: Depending on the application, the sensor's accuracy (e.g., ±1.0% FSO) may be sufficient or may require a more precise sensor.
