SEEcure On-Line UV Monitoring
Lamp decay, poor condition of the reflector and general contamination will reduce the lamphead’s ability to provide economical curing. GEW’s SEEcure on-line UV monitoring ensures continued performance by providing a means to determine the onset and degree of deterioration. Given this information, maintenance can be scheduled-in for a convenient time and spare parts such as UV lamps can be obtained well in advance.
How it Works
A small optical device fitted in or around the lamphead senses UV output. The signal is processed and a proportional readout is displayed on the operator control panel, together with readouts for any other lampheads in the system. During manufacture the device is calibrated to establish a reference output for a new reflector and lamp and the displayed value is matched to the lamp power percentage.

The Operator Control Panel
Figure 2 shows a typical SEEcure operator control panel. The central column shows the lamp power (%) as set by the operator and the right-hand column “UV%” shows the readout from the UV monitor. In the example, the values for lamp power (%) and UV% closely agree for all but lamp six. Lampheads one through five are shown to be in good condition whereas lamphead six requires investigation.
