IP68 waterproof design and double sealed sensor further reduce the safety risk caused by leakage and increase the service life in humid environment

The new circuit and firmware are upgraded, and the dynamic range is increased by 25%. It has advanced functions such as waveform display and intelligent diagnosis, so that a large number of range measurements can be easily completed.

Inherit the classic and focus on the experience

According to the “customer’s choice” ranking of the world-famous industrial control website Control1 in 2020, abb liquid level products rank first in the magnetostrictive category.

In the 1970s, K-TEK brand instrument won the favor of users all over the world with its excellent performance and flexible customization experience, and became the memory of a generation of instrument people. Its unique magnetostrictive liquid level transmitter, with a number of patents, flexible installation methods and stable performance in the face of harsh working conditions, has been in the forefront of high-end liquid level measurement instruments for a long time, replacing many kinds of traditional liquid level measurement methods, providing customers with an ideal experience of “installing it and forgetting it”.

In 2010, abb completed the acquisition of K-TEK. ABB’s global R & D platform and 100 years of production and operation experience make K-TEK series products even more powerful.

Basic principle and structure of ABB magnetostrictive liquid level gauge

Magnetostrictive level gauge based on the principle of vibration wave acquisition under the excitation of magnetic floating ball, has unique technical advantages compared with traditional radar, ultrasonic and other liquid level products under complicated conditions such as high temperature, strong corrosion, steam, foam, emulsified layer and liquid interface. Weak vibration wave collection requires sensitive and reliable sensors and software and hardware algorithms to deal with various interference sources. Technical breakthrough and long-term function polishing are essential.

1. The electronic device generates low-energy current pulses at fixed intervals.

2. With the fixed cycle current pulse excitation, a magnetic field is induced around the magnetostrictive line in the probe rod.

3. The induced magnetic field interacts with the magnetic field of the magnetic float to produce torsional stress wave. The torsional stress wave propagates from the position of the magnetic float to both ends of the magnetostrictive line at a known speed.

4. The patented sensing element used in the transmitter component converts the received mechanical torsion into an electronic return pulse.

5. The microprocessor-based electronic device measures the elapsed time (flight time) between the start pulse and the return pulse and converts it into a position measurement proportional to the float level.

ABB’s new generation magnetostrictive LMT series products have achieved leapfrog upgrading on the basis of the classic generation magnetostrictive product K-TEK at100 / 200, so that the product stability and use experience have reached a new height, especially the response ability to severe working conditions has been greatly improved. ABB magnetostrictive liquid level gauge has entered the era of 2.0.
