| 2. Rotational fixture |
| Circumference Gauge is designed to be used with the rotational fixture. Miniature servo motor & drive will be used to rotate sample at 1000 rpm (approx.), speed can be set through the software. |
Measurement data such as circumference and ovality depend upon the rotation of the sample. |

| 3. PC with suitable configuration |
| PC with suitable configuration is used along with a though beam sensor from Keyence. Sensor has measurement accuracy of 5 micron. User friendly s/w software is made using SCADA. Circumference is found measuring diameter of the cigarette. |

| 4. Laser Beam |
| The red laser beam emitted from the visible laser diode in the transmitter is converged into a parallel beam by the transmitter lens. When the laser beam is interrupted by a target, a shadow with an era proportional to the target size is projected on the receiver. The one-dimensional CCD image sensor scans and calculates the shadow area and position at a 780 c/s sampling rate to measure target dimension or position. |
