Kelebihan Teknikal Teras
-
High Sensitivity for Density Applications: The 249 series is engineered to react to extremely small changes in specific gravity. This high resolution makes these sensors ideal for monitoring fluid density or interface levels where the difference in weight between two liquids is minimal.
-
Heavy-Duty Pressure Ratings: These sensors are built for extreme process conditions, with available ratings up to CL2500. This ensures structural integrity and safety in high-pressure steam, chemical, or oil and gas applications.
-
Low-Friction Mechanical Design: To ensure a precise response to low-level signal changes, the sensor utilizes a knife-edged driver bearing. This design minimizes mechanical friction, ensuring that displacer movement is translated accurately to the torque tube and controller.
-
Maintenance Efficiency: The torque tube, which is the critical sensing element, can be replaced without the need to remove the entire torque tube arm. This modular approach significantly reduces downtime and labor costs during routine maintenance or part replacement.
-
Customized Depth Control: By utilizing different displacer stem lengths, the sensing element can be positioned at the exact depth required by the process, bypassing internal vessel obstructions or targeting specific fluid zones.
