주요 이점 및 장점
Versatile Seal Selection: The STR800 supports a vast array of seal types to match specific process requirements. From flush flange seals for standard tanks to sanitary seals for pharmaceutical grade clean-in-place (CIP) environments, the system is engineered for maximum application flexibility.
Enhanced Capillary Durability: To protect the critical fill fluid and ensure long-term reliability, the STR800 offers ruggedized capillary protection. Options include stainless steel armor and PVC-coated stainless steel armor, preventing mechanical damage and environmental corrosion in harsh field conditions.
Exceptional Thermal Stability: Remote seal systems are notoriously sensitive to temperature fluctuations in the capillaries. The STR800 utilizes advanced compensation algorithms to account for density changes in the fill fluid, ensuring that your level or pressure reading remains accurate even as ambient temperatures change throughout the day.
All-Welded Meter Body: The transmitter features a welded meter body design, which minimizes potential leak points and enhances the vacuum rating of the assembly. This is particularly critical for vacuum distillation applications where air ingress must be prevented at all costs.
Modular Architecture: Consistent with the SmartLine family, the STR800 electronics and display are modular. You can replace the communication module or upgrade the display in the field without disturbing the delicate capillary system or the process connections.
Integrated Diagnostics: The transmitter monitors the health of the remote seal system. It can detect issues such as a ruptured diaphragm or a significant loss of fill fluid, providing maintenance alerts before the measurement fails completely.
