Magtech™ MLT Level Transmitter – Magnetostrictive

Advanced Magnetostrictive Technology For Precision Measurement

The Rosemount™ Magtech MLT Magnetostrictive Level Transmitter represents Emerson’s highest standard for non‑invasive and direct‑insertion level measurement. Designed for applications demanding precise monitoring under extreme pressure and temperature conditions, the MLT merges smart digital electronics with the well‑proven magnetostrictive sensing principle. This transmitter detects the magnetic field within a float and instantly converts it into an accurate output signal, providing continuous level data to the control system. The system ensures exceptional repeatability and resolution, far surpassing mechanical or guided wave alternatives in harsh environments. Whether installed internally within piping or externally mounted to a magnetic level indicator, the MLT delivers seamless, reliable performance tailored for industrial precision and safety compliance across critical operations.

Durable Design For Harsh Industrial Environments Globally

Engineered for environmental extremes, the Rosemount MLT operates efficiently within a stunning temperature range from ‑200 °F to 750 °F (‑129 °C to 399 °C), offering resilience where conventional devices would fail. Its stainless‑steel construction ensures high corrosion resistance and compatibility with aggressive media such as acids, hydrocarbons, solvents, and cryogenic fluids. The transmitter’s compact housing resists vibration and mechanical shock, enabling installation on reactor vessels, high‑pressure separators, or steam boilers without optical degradation or signal shift. Advanced sealing techniques prevent fluid ingress under high pressure, maintaining long‑term reliability. Global maintenance teams favor the MLT because of its mechanical robustness and ability to preserve calibration accuracy for years with minimal intervention—ideal for asset reliability programs and continuous production environments.

Flexible Integration With Modern Control Architectures

Connectivity is central to the MLT’s digital intelligence. Emerson equipped this magnetostrictive level transmitter with universal communication protocols—4‑20 mA with HART® and Foundation™ Fieldbus—to ensure it fits seamlessly into existing plant infrastructures. Operators can configure and monitor the instrument locally through its integral display interface and tactile push‑buttons, or remotely through process control networks. Built‑in diagnostics continuously evaluate device health via HART messaging, notifying users instantly of any abnormal condition. These features facilitate predictive maintenance, drastically reducing downtime compared with legacy level monitoring systems. The modular design simplifies calibration and firmware updates, guaranteeing long‑term system scalability for modern digital plants pursuing IIoT and smarter automation platforms.

Specific Industrial Applications Demonstrating Exceptional Versatility

The Rosemount MLT serves a wide array of industries with remarkable flexibility and reliability:

• Oil & Gas Production: monitors separator levels, wellsite storage vessels, and hydrocarbon interface boundaries under extreme pressure and temperature conditions.
• Chemical Processing Plants: maintains level control in aggressive fluid reactors, distillation columns, and solvent tanks using corrosion‑resistant housings.
• Power Generation: assures feedwater boiler monitoring and condensate tank management with immunity to thermal stress fluctuations.
• Pharmaceutical and Food manufacturing: provides precise liquid measurements in pressurized sterile tanks without invasive contact, aiding clean‑in‑place cycles.
• Cryogenic Gas Facilities: delivers reliable measurement for storage of liquefied nitrogen or oxygen at temperatures near ‑200°F.

These specialized applications illustrate the MLT’s adaptability—from heat‑intensive refinery operations to ultra‑low‑temperature research systems—proving it an indispensable solution for complex industrial measurement challenges.

Seamless Compatibility With Magtech Magnetic Indicators

The MLT Magnetostrictive Transmitter is expressly designed to integrate with Emerson’s Magtech Magnetic Level Indicator (MLI), creating a powerful dual‑instrument solution. When mounted externally to the MLI chamber, it captures the precise position of the magnetic float without contacting the process fluid, achieving true non‑invasive measurement. This unique configuration is especially advantageous in hazardous or toxic applications where process isolation is essential. Combining visual indication with electronic transmission offers operators both local readability and remote monitoring—a perfect synergy of safety and efficiency. By merging these technologies, Emerson has provided industry with an intelligent, maintenance‑free system capable of high‑accuracy measurement in high‑pressure and high‑temperature conditions, further reinforcing Emerson’s legacy of instrumentation excellence.
