    液位,高溫料位測距傳感器 LDM42A-V

    液位,高溫料位測距傳感器 LDM42A-V

    液位,高溫料位測距傳感器 LDM42A-V

    It distinguishes itself through high precision as well as high independence from the surface of the measuring object. The red, visible laser beam allows for easy alignment. The sister model LDM42A has been further developed for fast distance measurements on white surfaces.

    • Distance measurement and determination of position
    • Diameter measurement of rolls / coils 
    • Fill level measurement 
    • Position control 
    • Monitoring of safety-relevant parts 
    • Monitoring of lifting plants / lifting height measurement and positioning of elevators
    • Monitoring and positioning of cranes and conveyor systems
      • Millimeter precise measurement on various surfaces 
      • Long range reflector-less distance measurement 
      • With additional reflectors on the target object measurements over 100 m 
      • Operation in extreme ambient temperatures with high precision and range
      • High supply voltage range between 10 V and 30 V DC with low power consumption 
      • Safe operation through laser class 2 
      • Easy adjustment through visible laser beam 
      • One connection cable for supply voltage, serial data interface, switching and analog output 
      • Customized parameterization via PC 
      • Display of measured values in meters, feet, inches and others due to free scaling
      • Robust, compact housing, easy to install, protection standard IP 65
    • Measuring range1
