spool is empty, the event is detected automatically thanks to the tape sensors. The tape
replacement procedure must be performed manually by the operator. The measurement tape
is one of the main parts of the system.
TAPE SENSORS
The two tape sensors are used by the instrument software to detect the amount of tape on the
un-roll and roll-on spools.
LIGHT SOURCE
The light source integrates groups of LEDs of different light wavelengths. It is one of the main
parts of the system.
DETECTOR
The detector detects what amount of light passes through the measurement tape. A special
algorithm is used to calculate the black carbon concentration using the information from the
detector and the flow-meter.
FRONT PANEL DOOR
The front panel door can be opened which allows the access to the instrument for tape
replacement or chamber cleaning.
DISPLAY and TOUCH-SCREEN
The display and the touch-screen are the main user interfaces of the instrument. Using this
interface the operator can perform all necessary operations for proper functioning of the
instrument.
