ABB Application Note - ABB LM80 Laser Level Application in Salt Industry
Summary
The LM80 Laser Level Transmitter provides highly accurate, reliable measurement for industrial materials, such as salt pellets. This technical guide details the successful application of the transmitter in challenging environments—specifically a salt plant where metal support beams and material variation previously hindered readings. It is designed for professionals requiring precise level monitoring, offering superior performance compared to traditional ultrasonic or radar systems in complex settings while maintaining durability against dust buildup.

LM80 Laser Level Transmitter Salt Industry Application
Measurement made easy The LM80 Laser level transmitter has been applied successfully at a salt plant in the Midwest of the United Sates. The application involves measurement of salt in pellet form. The customer had previously tried to use ultrasonic and radar transmitters unsuccessfully in the application.
In this particular application the bins have support beams that caused the ultrasonic and radar signal to detect the beams instead of the product after the bin was 30% empty. As a result 70% of the bin measurement was not accurate. Additionally the bin filled with a peak in the middle and emptied with slump in the middle. Even in the area with no metal beams this “Peaking and Slumping” caused poor performance from the ultrasonic and radar transmitters.
An LM80 was mounted on top of the bin and aimed to avoid the metal supports. The narrow width of the laser beam allowed for positioning the laser beam between the metal supports. The results were excellent, the LM80 responded with the correct measurement, verified with a tape measure. Dust density was not an issue for the LM80 in the pellet application however measuring salt when it is fine can sometimes present a problem due to high dust levels. For those applications where dust becomes too thick ABB Guided Wave Impulse Radar transmitters positioned to avoid the metal supports can be used.

Frequently Asked Questions
What is the LM80 suitable for in challenging environments?
The LM80 Laser level transmitter was successfully used for measuring salt in pellet form.
Why did previous ultrasonic and radar systems fail in salt measurement?
Support beams caused signals to detect the metal instead of the product, especially when the bin was 30% empty.
What alternative device is recommended for high-dust level applications?
For very thick dust levels, ABB Guided Wave Impulse Radar transmitters positioned away from supports can be used.
Does the LM80 perform well with various salt conditions?
It performed excellently in pellet form; however, fine salt dust can still present a problem due to high dust levels.
