Thông tin sản phẩm
- The LDM41A is an optoelectronic distance measuring device for industrial applications with an analogue interface (4 mA to 20 mA).
- It works contact-free on the principle of comparative phase measurement (amplitude modulation) and facilitates precisely accurate measurement of distances.
- 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
