How pressure and temperature affect instrument selection
Technical guidance on separating normal conditions, design limits and material compatibility.
Normal conditions and design limits are different
Selection should record both the normal operating point and the maximum condition the instrument may experience.
Materials and seals must match the process
Temperature and pressure affect body, lining, seal, connection and enclosure decisions. Compatibility must be reviewed against the real medium.
Share the complete operating envelope
A useful enquiry includes pressure, temperature, flow range, ambient conditions and installation constraints rather than a single nominal value.
