SI-JET
SI-JET spray jet control systems use light barriers to monitor the density, symmetry and cone angle of the spray leaving a nozzle, inline.
SI-JET systems check the spray jet in transmitted light with three light barriers or three fibre-optic bundles built into a transmitter and a receiver unit. How much the jet attenuates the light indicates its density, and the differences between the channels indicate symmetry and cone angle, so blocked or incorrectly set nozzles are detected in time. Compressed-air connections integrated in the transmitter and receiver keep the system insensitive to dirt.
For the same task there are also the single-channel SPECTRO-1-FIO-JC and two-channel SPECTRO-2-FIO-JC fibre-optic sensors, and L-LAS-TB-…-AL-SC systems that record the jet profile with a laser light curtain. The fibre-optic versions can be used inside and outside potentially explosive atmospheres. The systems monitor nozzle faults on the line while spraying is in progress.
