主なメリットと利点
Precision Displacement Technology: The DLC3010 utilizes a torque tube and displacer assembly to detect level changes based on Archimedes’ Principle. As the liquid level rises, the buoyant force on the displacer changes, rotating the torque tube. The DLC3010 senses this rotation with high resolution, providing a stable and accurate measurement even in turbulent or high-pressure conditions.
Dynamic Temperature Compensation: Variations in process temperature can significantly change fluid density, leading to level measurement errors. The DLC3010 can be integrated with a temperature sensor (RTD) to provide real-time density correction, ensuring the reported level remains accurate regardless of thermal fluctuations.
Easy Configuration and Calibration: Featuring a user-friendly setup, the DLC3010 can be calibrated using a handheld HART communicator or a PC with ValveLink software. The instrument allows for “dry calibration,” where the device is set up based on fluid properties and displacer weight without needing to fill the vessel, saving significant time during commissioning.
Advanced Diagnostics: Beyond simple level reporting, the DLC3010 monitors the health of the entire sensor assembly. It can detect issues such as a coated displacer, a leaking torque tube, or mechanical binding, allowing for predictive maintenance before a process failure occurs.
Flexible Fluid Management: The device allows operators to define and select various process fluids from a built-in library. This enables quick changes to the measurement parameters if the process fluid is updated, without requiring a complete hardware re-calibration.
Rugged and Reliable Design: The DLC3010 is built to withstand harsh industrial environments. Its electronics are housed in a robust, dual-compartment enclosure that protects sensitive components from moisture and corrosive gases, while the linkage-less internal design minimizes mechanical wear.
