LEDAER UTD/UFD Series
Intelligent Displacement Level Transmitter: The Industry Standard for Extreme Industrial Environments
📌 Overview
The UTD/UFD Series is a precision instrument designed for the most demanding liquid level and interface measurements. Operating on Archimedes’ principle of buoyancy, it translates the change in buoyant force on a displacer into a high-accuracy electronic signal via a rugged torque tube system. This series is the industry standard for high-pressure vessels where extreme stability and reliability are non-negotiable.
✨ Key Features & Advantages
High-Precision Interface
Excels at tracking liquid-liquid interfaces (e.g., oil-water) with density differences as small as 0.08 g/cm³.
Extreme Pressure Rated
Standard models handle 6.3 MPa, with custom high-pressure versions reaching a massive 42 MPa.
Thermal Master
Reliably operates from cryogenic -196°C to superheated +450°C applications.
Durable Isolation
The torque tube design isolates the sensor from process media, ensuring a long, maintenance-free life.
