LDM301A
The LDM301A measures distances to targets up to 3000 m away with a precision down to the centimeter. It is able to detect the speed of moving objects with high accuracy. Operated without a reflector, the LDM301A convinces with a range of 300 m on almost each surface.

LDM301A
In addition to the large working range, the LDM301A is characterized by very short measuring times down to 0.1 ms. The compact design of the device, the easy set-up and the standard interfaces RS422 or RS232 allow for easy installation and operation. The status of the device can be monitored via LED display during operation. The integrated heating is automatically controlled and ensures reliable operation at temperatures as low as -40°C.
Applications
- Process monitoring in steel and rolling mills
- Fill level measurement
