Binocular laser triangulation sensors (series LD2)

 

Binocular laser triangulation sensors, series LD2

Binocular laser triangulation sensors, series LD2:

A special series of sensors for working with complex surface relief. Owing to two sensors symmetrically located relative to the laser beam, the binocular sensor is able to work with a deeper relief without signal loss.

 

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.
