| M72 Double sensor PSD analog
Implemented into this double sensor is a second receiver for highest accuracy. In this manner a resolution from 0,0001 mm to 0,001 mm (0.004 mil to 0,04 mil) is reachable.
For distinct structures, scratches, pale to dark transfers and tinned surfaces this fast laser sensor is particularly suited.
By light point interpretation with two receivers, falsifications on pale-dark transfers and on interferences will be substantially better centralized. Like this, much higher accuracies are achievable than with a single sensor.
Like nearly all our sensors, also the M72 works according to the principle of triangulation. The measuring rate of 10 kHz (sampling frequency 54 kHz) and the response time from 0.1 ms to 67 ms are adjustable.
The small light point diameter (0.3 mm) (0.1 in.) enables the recording of tiny units.
Three variations with measuring ranges of 0.5 mm, 2 mm and 4 mm (0.02, 0.07 and 0.16 in.) are obtainable.
Due to the separated evaluation electronics, it was possible to minimize the sensor head. Also included in delivery is a 2 m (78.7 in.) long connection cable.
Preferred areas of application: • changing pale-dark transfers
• distinct structures, scratches
• tinned surfaces
• mirroring surfaces
• attendance check
• recognition of position
• measuring length, angle, thickness
• verify material property
   
This sensor was developed especially for diode measuring. It was to be examined, whether the tinned IC-legs are bent. The tolerance limit was set to 0.1 mm (0.004 in.). In the same cycle, it was to be determined, if the previously roughened, black body is too deeply scratched. |
