Laser triangulation sensors (series LD3)

 

Laser triangulation sensors, series LD3Laser triangulation sensors, series LD3:

A special series of compact sensors, developed for applications that require small size and weight of the device. 

 

The sensors are designed for use in automation systems and contactless measurement of different geometric parameters: thickness, straightness, inner and outer diameters, scanning the profile of objects with complex forms, determining the position of objects. On the basis of the sensors, a system of automatic control of different processes can be built. In addition, the sensor has the ability to connect the positioning signals from the machines for the realization of 3D scanning systems.
