Thickness Measurement System

The system refers to non-contact laser thickness measurement equipment and is intended for precise measuring of thickness of sheet materials such as tapes, boards, plates, and so on. It is a stand-alone software and hardware system that contains laser sensors and an indication device.

System parameters can be changed for a specific task.

Thickness Measurement System. Specification

Power supply, V 220 (±10 %) for AC network with frequency of 50 (±1) Hz
Power consumption, W 10
Operating conditions:
  Ambient temperature, °С +1...+35
Relative humidity, % 65 (at 25°С)

Note: System parameters can be changed for a specific task.


The system can support an unlimited number of thickness control points. Each control point is one sensor mounted according to Scheme #1 (Figure 1, left) or two sensors mounted according to Scheme #2 (Figure 1, right).

According to Scheme #1 (one sensor for one point), the material thickness is a difference between the distance from the base surface on which the material is located, and the distance to the upper surface of the material measured by a sensor. The sensor position is calibrated relative to the base surface.

According to Scheme #2 (two sensors for one point), the material thickness is a difference of distances to the material surfaces measured by each of the sensors. The position of sensors is calibrated relative to each other.
