The Optical Flux Plume System uses a sensor mounted opposite an LED light source. A sponge pad is mounted above the Flux Plume Sensor assembly to absorb the flux spray during Plume Sensing operation.
The flux head is positioned below and between the two sensors and the signal is first measured before the flux is fired. This measurement is held in a “sample and hold circuit”, while a second measurement is taken during flux firing.
The two readings are then compared, and the difference is used as a measurement of the Flux Plume. Threshold levels can be set at to provide an error message when the Flux Plume Reading is out of the threshold range.
