5. SOR General description The measuring devices type LSPEED smartsensor are laser sensors based on the Doppler effect and are used for non contact measurement of length and velocity of surfaces with diffuse reflection They provide extremely accurate measurement without markings or rods This measuring equipment is thus particularly suitable for its use in process control and quality assurance It allows the optimization of cutting operations positioning and dosing in the case of flat or rope like material such as paper metal wood textile plates sheets wires and cables Function The measurement is non contact and therefore completely free of wear and tear is performed by scanning the product from a laser based measuring unit that projects a striated pattern on the object The measured object backscatters the laser beam into the measuring unit The frequency of the backscattered light is directly proportional to the measured object s velocity 1 2 TECHNICAL DATA Technical data of the LSPEED smartsensor are listed in the following Table 1 Speed measuring range dependend on type of sensor 2 m min 2400 m min Stand off distance depth of field 120 mm 5mm 10mm 240mm 10mm 20mm 58 rnm Table 1 Technical data uSPEED smartsensor 1 3 SCOPE DELIVERY The standard scope of delivery of the LSPEED smartsensor is Sensor head in the following uSPEED smartsensor Sensor cable Plastic screws an
