2 General Description 

 
The laser measuring devices of the series LE are optical sensors, with which larger 
distances can be measured without contact and serviceable for controller. The 
measuring system consists of the real measuring device with laser light source, 
receiving optics, electronic evaluation and data interface as well as a reflector. The 
device sends out a modulated light beam which is reflected by the reflector. From the 
phase difference of the sent and received light beam the distance is measured 1000 
times per second. Thus the LE is suitable also directly for the position feedback in 
controller loops. 
 
According to the requirements the laser distance measuring devices of the series 
LE-200 Interbus-S are configured either directly over the Interbus-S or with the PC-
programming software "TRWinProg".
