LDE LASER TRIANGULATION SENSORS

 

LASER TRIANGULATION SENSORS

LDE SERIES

 

General information

The sensors are intended for non-contact measuring and checking of position, displacement, dimensions, surface profile, deformation, vibrations, sorting and sensing of technological objects as well as for measuring levels of liquid and bulk materials.
The series includes 12 sensors with the measurement range, from10 to 2500 mm and the base distance from 230 to 1 mm.  The Series is divided into 3 groups. The first group includes the sensors with large bases and short measurement ranges, second group includes sensors with medium bases and ranges and the third group is the sen-sors with long ranges.
There are two options of laser mounted in the sensor, RED or BLUE laser. The use of blue lasers instead of conventional red lasers greatly enhances capabilities of the sensors, in particular, for such uses as control of high-temperature objects and organic materials. Custom-ordered configurations are possible with parameters different from those shown below.

■■ Large-base and long range laser sensors

■■ Measuring ranges from 10 to 2500 mm

■■ Linearity ±0.1%

■■ Resolution ±0.01%

■■ Sampling rate up to 9.4 kHz

■■ RS232/RS485/Ethernet/CAN +4...20 mA/0...10V
