MEASUREMENT VOLUME Laser surface velocimetry: Built for precision Non-shift, base systems Polytec LSV Laser Velocimeters use a modified laser Doppler technique to measure the speed of material passing by the sensor. The beam of a single laser diode is split into two beams. These beams are superimposed on to a moving surface at an angle φ, relative to the optical axia. As the two beams overlap, constructive and destructive interference occurs, generating a static pattern of light and dark fringes within a specified measurement volume called the depth of field. The fringe spacing, Δs, a key...

LSV-A-110 Connection Box The connection box is completely wired for instant operation and contains a full terminal block, an universal power supply and LAN connector. LSV-A-120 Air Wipe With Quick Exchange Window A front-mounted, aerodynamically optimized air wipe unit keeps the sensor's optical window free of dust and steam. For cleaning or replacement, the quick release window can be easily exchanged. LSV-A-124 Measurement Installation Kit The C-Frame accessory kit allows an easy integration into the housing of a c-frame of any thickness gauge. A built-in cooling plate keeps the sensor...
