1.3  Use as intended  

The sensor system is suitable only for non-destructive testing of 

round 

material

Diameter range:   see  2.4 Technical Data  
Smaller diameters and larger diameters may not be admitted into the 
sensor system under any circumstances. 
 
Material with a cross-section which is anything other than round may not 
be admitted into the sensor system under any circumstances. 

The sensor system may be operated only in conjunction with a suitable 
conveying mechanism and a lifting table. 

On no account may you convert or modify the sensor system arbitrarily, 
for reasons relating to safety. 

 

DANGER

Masses rotating at high speed pose a serious danger to your life if the 
machine is operated incorrectly.  
Never touch the rotating sensor components. 

 

NOTE

The information on operation, servicing and maintenance prescribed in 
these operating instructions must be followed strictly. 

 

1.4  Dangers posed by accessories 

Transport mechanisms, lifting table and external control equipment must 
not render the protective safety devices of the sensor system inoperable. 

1.5 Emissions 

See 2.6 Environmental conditions.
