LDM51A-x Lumos

The LDM51A-x Lumos is a hardier version of the LDM51. The LDM51A-x Lumos provides non-contact measurements up to 100m with no additional reflectors required. Fast measurements are also possible because of the high measuring frequency (100 Hz). The LDM51A-x has a stainless steel housing with water cooling capabilities, which was designed to withstand harsher conditions, such as outdoor areas, steel plants, paper mills, etc. 

Operating Principle:

Impulse back-mixing

Features:

• Contactless laser distance measurement on nearly every type of surface
• Stainless steel housing with water cooling capabilities
• Reliable operation in outdoor applications under high common light influence
• Measuring even on extremely bad reflecting targets (coal, rubber, rust)
• Riskless usage due to eye-safe visible laser beam (Laser class 2, EN 60825-1:2007)
• 3 programmable digital output lines
• Freely programmable and scalable analogue interface (4 … 20 mA)

Application:

• Plant automation and process technology under very harsh conditions
• Positioning applications in transportation and logistic
• Distance measurement in mining, building, forestry and material-handling technology
• Machine-observation and –positioning in metal industry e.g. rolling-mills, de-coiler
• Long term observation of buildings and technical installations, e.g. churches, tide gates, docks
• Position and height detection in crane applications
• Level measurement in silos and heaps on materials like sand, earth, feed, cereals, cement
• Thickness, length and width detection of hot metal slabs
• Hot metal detection
• Diameter of steel coils
• Distance measurement on hot glowing steel with temperatures over 1300 °C
