Laser Doppler Sensor LMC-L-XXXX-XXX / LMC-LB-XXXX-XXX 

High accurate, contact less measurements of length and speed - the fastest and state-of-the-art laser on the market

Laser doppler sensors of the LMC-L-XXXX-XXX / LMC-LB-XXXX-XXX series are used for detecting length and speed, controlling synchronized processes and for securing quality during several production processes.

The Laser-Doppler-Technology is detecting und evaluating diffuse light on moving materials. Therefore this technology offers many advantages for controlling ongoing production processes of continuous material.  Because of the non-contact measurement, there are no typical fault sources, such as mechanical slip or abrasion. Based on the very high update rate of 0.04 ms, detected materials will be recognized in real time and highly accurate measured. Detecting can be managed on all diffusely reflecting surfaces up to 1,300 °C temperature on the surface.

Laser Doppler MesssystemThe sensors are characterized by their compact design, a long lifetime and their easy use. The adapters and protective housings allow an easy and safe installation of the sensors at the production lines. The sensors work reliable under harsh environmental conditions.

The sensors of LMC-L-/LB series can show the detected values on a simple display. Moreover the sensors can be integrated easy in control systems with the help of standard interfaces.
