Technical Data Description
Operating temp: - 20 ...+   60 degree C The roughness sensor has a built in infrared light source.  Scattered light reflected from a rough surface is analyzed and the roughness factor is calculated in absolute or relative units. Some applications may need calibration.  Due to the sensitivity and high sample rates it is advised that the surface sensor be mounted firmly avoiding any environmental light.  The roughness sensor is a one dimensional instrument.  Circular movement over the probe changes measurement results.

Technical Description
To obtain the relative roughness size R, customer must apply the next formula:
Sr - intensity of reflected component    
Ss - intensity of the scattered component
k scaling coefficient
The scaling coefficient k can be any number. To provide the optimum range-resolution relation, for machined surfaces k is recommended to be 100.
