    "No product fully meets the high pressure range requirement of 15000 psi; Rosemount 3051S and SITRANS P320/P420 come closest but still fall short.",
    "Rosemount 3051S excels in accuracy and temperature range, making it suitable for custody transfer and high temperature applications, but lacks explicit certifications and corrosion resistance details.",
    "Output signal support with 4-20 mA and HART protocol is strong across all products, supporting remote diagnostics and maintainability to some extent.",
    "Certification and corrosion resistance information is generally lacking, representing a potential risk area for customers requiring compliance with industry standards.",
    "Long-term stability data is not explicitly provided for any product, making it difficult to fully assess suitability for applications requiring minimal drift."
