Selection Suggestions and Precautions
Selection Suggestions:
- Confirm exact pressure range requirement (–100 to +300 mbar g is standard for this model).
- Verify compatibility with the existing tank gauging system (especially Saab TankRadar / Rosemount).
- Ensure the intrinsically safe parameters match the system barriers and installation requirements.
- Check cable length and connection type needed for the installation.
Precautions:
- This is an intrinsically safe device — installation must comply with ATEX/IECEx requirements and local regulations.
- Only use approved barriers and follow entity parameter limitations (Ui, Ii, Pi).
- Protect the sensor from mechanical damage and excessive pressure beyond the rated range.
- Proper grounding and cable shielding are important in marine environments.
- Calibration and functional testing should be performed according to manufacturer and class society guidelines.
- When replacing, match the exact type (2967/B) and range to ensure system compatibility.
