ABB Magnetostrictive Level Transmitter LMT200
Overview
The ABB LMT200 is a magnetostrictive level transmitter engineered for accurate, continuous level measurement in a wide range of industrial applications. Where ABB’s LST300/LST400 ultrasonic transmitters measure level from above the process surface, the LMT200 uses a float-and-probe magnetostrictive principle, delivering real-time level data with the exceptional precision that comes from direct mechanical coupling to the liquid surface rather than acoustic echo.
Seven Star LLC supplies the ABB LMT200 to storage tank, chemical reactor, and oil and gas process operators across Oman and the wider GCC as an experienced supply partner for genuine ABB instrumentation. Every unit is supplied on request with manufacturer documentation, and supported locally with probe-length and mounting guidance.
Operating Principle
The LMT200 uses a float with a built-in magnet that moves along a probe as the liquid level changes; a magnetostrictive pulse traveling down the probe interacts with the float’s magnetic field, and the transmitter precisely times the returning pulse to determine level position. This allows highly accurate level detection without any moving parts inside the instrument itself – only the external float moves, while the sensing electronics remain static. Accuracy reaches ±0.01% of full scale (or 1.27 mm, whichever is greater), with repeatability of ±0.005% of full scale and an update rate of 10 measurements per second, giving the LMT200 measurement performance that rivals far more expensive continuous-level technologies. The LMT200 is designed to external-mount onto ABB’s KM26 magnetic level gauge, adding electronic transmission to a proven visual indicator rather than replacing it.
Built to operate in harsh environments, the LMT200 is ideal for monitoring liquids in storage tanks, chemical reactors, and oil and gas processes. It features robust construction and high resistance to temperature, pressure, and corrosion, making it a dependable choice for mission-critical operations where measurement stability cannot be compromised.
Engineering Design of the ABB LMT200
The LMT200 supports HART communication protocol, enabling seamless integration with existing process control systems, and offers multiple mounting options with easy installation and minimal calibration requirements. Whether dealing with hazardous chemicals, high-temperature liquids, or sensitive process media, the LMT200 delivers consistent results across a wide range of demanding process conditions.
Its non-contact measurement capability – in the sense that the sensing electronics never touch the process fluid directly – ensures minimal maintenance and long-term performance stability, a key advantage over contact-based level technologies in aggressive or fouling process media. Process temperature is rated from −195.5°C to 426.6°C (−320°F to 800°F) with options, covering everything from cryogenic storage to high-temperature process vessels, while ambient temperature is rated −40°C to 85°C. The sensor tube and probe are 316/L stainless steel, the enclosure is cast low-copper aluminum with powder coat or 316 stainless steel, and standard probe lengths run from 304.8 mm to 15.24 m (1 to 50 ft), with 90-degree variants available up to 7.62 m (25 ft) for tight installation clearances. Floats are engineered with a minimum of 75 grams of buoyancy and are available in titanium, Monel, Hastelloy C, stainless steel, or coated plastic to match the process fluid’s specific gravity and chemical compatibility.
