Spray jet control using two-channel sensors

Two-channel spray jet sensor SPECTRO-2-FIO-JC

The transmitted light fiber optic of the SPECTRO-2-FIO-JC two-channel version of a spray-jet monitoring system suits it to use both inside and outside a potentially explosive atmosphere. In this process, two parallel directed white light beams (a collimation of the white light is achieved by a suitable attachment optic) is directed onto the spray jet and the light arriving on the side opposite the spray jet is focused by a receiver optical attachment onto the front surface of the receiving fiber optics. The beam attenuation compared to the state when the spray jet is not present serves as a measure for the density of the spray jet, while the ratio of the two signals provides additional information about the spray jet symmetry.

The evaluation is supported easily by the SPECTRO2-SPRAY-CONTROL-Scope parametrization and monitoring software.
