Product DescriptionProduct DescriptionRosemount 5301 Guided Wave Radar Level TransmitterIn the landscape of industrial process automation, accurate and reliable liquid level measurement serves as the backbone of operational efficiency, safety compliance, and cost optimization. From the high-pressure vessels of oil refineries to the corrosive tanks of chemical plants, the demand for measurement solutions that can withstand extreme conditions while delivering precise data has never been more critical. Emerson's Rosemount 5301 Guided Wave Radar (GWR) Level Transmitter emerges as a pioneering technology in this domain, redefining industry standards for liquid and interface level measurement across diverse sectors.As part of the acclaimed Rosemount 5300 series—joined by the 5302 (specialized for dual liquid level and interface measurements) and 5303 (designed for solid materials)—the 5301 is engineered specifically for liquid level and submerged interface applications. What distinguishes this transmitter from conventional measurement tools is its ability to maintain exceptional accuracy regardless of process disturbances such as turbulence, foam, vapor, or varying fluid properties. Leveraging Time Domain Reflectometry (TDR) technology, the 5301 eliminates the limitations of differential pressure transmitters or ultrasonic devices, which often struggle with temperature fluctuations, density changes, or acoustic interference.1.Core Technology: Time Domain Reflectometry (TDR) ExplainedAt the heart of the Rosemount 5301's performance lies Time Domain Reflectometry (TDR), a proven measurement principle that has revolutionized guided wave radar applications.1.1 The Science of TDR MeasurementThe operational sequence of the Rosemount 5301 follows a precise four-step process that translates electromagnetic signals into actionable level data:Pulse Transmission: The transmitter generates low-energy, nanosecond-duration microwave pulses (operating at 1.2 GHz for optimal penetration of low-dielectric media) that travel down the immersed probe. This low-frequency design is particularly advantageous for measuring hydrocarbons and other fluids with low dielectric constants, a challenge for many high-frequency radar devices.Signal Reflection: When the microwave pulses encounter a boundary between media with different dielectric constants (e.g., air and oil, or oil and water), a portion of the signal energy reflects back toward the transmitter. The intensity of this reflection is proportional to the difference in dielectric constants—greater contrast results in stronger reflections, while minimal contrast (such as between two similar hydrocarbons) requires the 5301's advanced signal processing to detect.1.2 Advantages Over Conventional Measurement TechnologiesThe TDR principle inherent in the Rosemount 5301 addresses key limitations of traditional level measurement methods:Immunity to Process Variations: Unlike differential pressure transmitters, which require accurate density data and are affected by temperature changes, the 5301's measurements are independent of fluid density, viscosity, or temperature. Reliability in Challenging Environments: Ultrasonic transmitters often fail in dusty, vapor-rich, or foamy conditions due to signal attenuation. The 5301's probe-guided signals bypass these issues, as the physical waveguide ensures signal propagation directly to the measurement point.Low-Maintenance Operation: Capacitance level sensors require frequent calibration and are prone to drift in corrosive environments. The 5301's non-contacting measurement (relative to the probe surface) and robust probe materials minimize drift and reduce calibration needs.2. Technical Specifications and Performance CapabilitiesThe Rosemount 5301's technical specifications demonstrate its ability to meet the demands of the most rigorous industrial applications. From extreme temperature ranges to high-pressure environments, every parameter is engineered to deliver consistent performance while adhering to global industry standards.2.1 Precision and RepeatabilityAccuracy is the defining characteristic of the Rosemount 5301, with performance metrics that exceed industry averages:Reference Accuracy: ±0.1 inches (±3 mm) or ±0.03% of the measured distance, whichever is greater. For fluids with a dielectric constant >1.8, accuracy improves to ±1 mm (±0.04 inches), while for lower dielectric constants (<1.8), it maintains an impressive ±2 mm (±0.08 inches). This level of precision ensures compliance with strict inventory management and process control requirements.2.2 Environmental and Process TolerancesThe 5301 is built to withstand the harshest industrial conditions, with specifications that reflect its robust design:Temperature Range: The transmitter operates reliably from -320°F (-196°C) to 752°F (400°C), covering applications from cryogenic liquid storage (e.g., liquid nitrogen) to high-temperature chemical reactors.Pressure Rating: At 100°F (38°C), the 5301 handles pressures up to 5,000 psi (345 bar), and maintains 3,320 psi (228.9 bar) at 482°F (250°C). This high-pressure capability makes it suitable for refinery columns, High pressure boilers, and offshore oil production facilities.2.3 Dielectric Constant CompatibilityA key advantage of the Rosemount 5301 is its ability to measure fluids with extremely low dielectric constants, a challenge for many radar technologies:Minimum Dielectric Requirements: Coaxial probes or single probes installed in bypasses can measure fluids with dielectric constants as low as 1.2, while other probe configurations handle dielectric constants from 1.4 upward. Interface Measurement Capability: The 5301 excels at measuring interfaces between two liquids, even when the dielectric contrast is minimal. Its advanced algorithms distinguish between reflections from adjacent layers, making it ideal for water-in-oil separation tanks or chemical mixing processes.SpecificationMeasurement principleBased on the principle of time-domain reflectometryMeasurement range50mAccuracy±3mmRepetitiveness±1mmSignal Output4-20mAOperating temperature-196℃ to 400℃ (-320°F to 752°F)Operating pressureVacuum to 345 bar (5000 psi)Power supply42.4VCompany Profileabout usMain productKeRui (WeiFang) Automation Equipment Co., Ltd. is specialized in industrialautomation instrument development, production and sales, technical servicesand supporting equipment supply of specialized companies.
