The Yokogawa UT350-00 is a compact, two-wire ultrasonic level transmitter designed for non-contact, continuous level measurement of liquids in a wide range of industrial applications.
Key Features and Specifications
Measurement Principle: Non-contact ultrasonic (time-of-flight).
Mounting: Threaded or flange process connection (e.g., 2" NPT, G2, or various flanges).
Output Signal:
Analog Output: One 4-20 mA DC output (two-wire, loop-powered).
Digital Communication: HART® protocol is typically standard for configuration and diagnostics.
Power Supply: Loop-powered: 12.5 to 30 V DC, sourced directly from the 4-20 mA loop.
Display: Integral LCD display (standard) for local reading of level, distance, and diagnostics.
Measuring Range: Up to 5 meters (approx. 16.4 feet) for liquids. Note: The effective range can be less depending on the application conditions.
Accuracy: Typically ±0.25% of full scale under reference conditions.
Process Temperature: -40 to 80 °C (-40 to 176 °F) [Temperature at the transducer].
Process Pressure: Up to 3 bar (43.5 psi) at 80°C.
Enclosure Rating: Typically IP67 (NEMA 4X equivalent), providing excellent protection against dust and water ingress for outdoor and harsh industrial environments.
Key Features:
True two-wire design for easy installation and low cost of ownership.
Simple setup via the intuitive local interface or a HART communicator.
Built-in temperature compensation for stable readings in varying ambient conditions.
False echo suppression software to ignore fixed obstructions inside the tank.
