IntroductionMagnetostrictive level transmitters offering accuracy, safety and reliablility even in the harshest environments

Index

ABB‘s patented AccuTrakTM series Magnetostrictive Level Transmitter are the only level transmitters in the world to be IEC 61508 certified for use in SIL2 and SIL3 rated control loops. With over 200,000 installations worldwide, the AT series Magnetostrictive Level Transmitter continues to provide the highest accuracy and repeatability for liquid level applications in the oil and gas, power generation, chemical, food and beverage industries and many more.

These transmitters are used extensively around the world to provide continuous level indication, and transmission of an analog and/or digital signal for monitoring or control. The unique design allows increasing level sensing resolution, which is more than 100 times greater than a conventional reed switch type device. The AccuTrak™ Magnetostrictive Level Transmitter versatility allows direct in-tank installation or externally mounted to a magnetic level gauge. HART, Foun-dation Fieldbus and Honeywell DE protocol options make our magnetostrictive level transmitters compatible with most control systems.

Principle of operationMagnetostrictive transmitter offers one of the most accurate two wire liquid level technology in the world

Magnetostrictive level transmitters are one of the 10 technologies currently being offered by ABB that are utilized to control level in liquids or solids processes. The K-TEK AT transmitter is part of the liquid measurement product line and has been manufactured by ABB for more than 20 years. The AccuTrak level transmitter is based on the magnetostrictive principle, which detects the position of the float by using “time of flight“ technology to calculate distance. The AccuTrak level transmitter is a custom engineered device, characterized above all by its accuracy, repeatability and reliability. ABB‘s Magnetostrictive transmitter provides the highest temperature and probe length capabilities, and reliability.

Torsional wave sensorABB‘s patented torsional wave sensor is constructed so that it only responds to torques. This design achieves a voltage from the sensor when the torsional stress wave is detected and ignores all longitudinal vibrations. The sensor provides a maximum transfer of the torsional energy and provides self-cancellation of most other vibration influences. The result is an extremely high signal to noise ratio. This allows our customers to use the AccuTrack Magnetostrictive Transmitter in extreme applications. The AccuTrak‘s patented sensor allows for longer lengths and a wider range of temperatures and pressures.

The AT200 and AT600 Magnetostrictive Level Transmitters are used as a direct enhancement for the KM26 Magnetic Level Gauge to create a complete level measuring system for a wide range of total and/or interface applications. The AT Transmitter detects the position of the float within the magnetic level gauge chamber and provides continuous level reading via common industry protocols such as 4-20 mA, HART, Foundation Fieldbus and Honeywell DE; while deriving its source of power from the control loop. The resulting non-contact level measurement is highly accurate.

The AT100, AT100S and AT500 Magnetostrictive Level Transmitters are highly accurate devices designed to be directly inserted into the process. The AT series transmitters feature the finest technology available for liquid level interface measurement and control. These transmitters provide two independent outputs: one for interface and a second for total level. Interface level measurement is available for specific gravity differential down to .003. Most commonly applied to oil and water separator interface, this technique has applications in many processes. Others include: HF acid/propane vessels, desalters and sumps.

Process vesselsABB transmitters are used extensively around the world to accurately measure level in process vessels. High accuracy, quick startup, easy installation or high reliability are two of the most common reasons for choosing this technology. With ratings to 800°F/427°C and 2400 PSI/165 bar, magnetostrictive level transmitters are suitable for almost any application. HART, Foundation Fieldbus and Honeywell DE protocol options make our magnetostrictive level transmitters easy to connect digitally to most control systems. Internal LCDs provide local indication in 4-20 mA, percentage or engineering units.

Storage tanksConcerns of high accuracy, low maintenance and reasonable cost leads customers to install flexible probe versions of the magnetostrictive level transmitters in their storage tanks. With the ability to be easily installed to a maximum of 75 ft./23 m, almost any liquid storage application can be handled. Some common liquids include water, acids, caustics, propane, ammonia, oils, fuels, chemicals or waste liquids. An optional internal 20 point linearization table allows the magnetostrictive level transmitter to provide accurate output in horizontal or round vessels.

KM26 Magnetic Level Gauge InstallationThe addition of a magnetostrictive level transmitter to a KM26 magnetic level gauge creates a complete level measuring system and helps eliminate numerous bridles and unnecessary connections in the process. The most common benefits to this solution include: quick startup, easy installation, low maintenance, no calibration, reduced cost and no contact with the process fluids. The KM26 and AT level system is the preferred solution over sight glasses, DP transmitters, liquid level displacers or other problematic level instruments.
