ST-328 Xenon Stroboscope Array

The ST-328 is a permanent mount stroboscope array utilizing bright high powered xenon style lamps. The ST-328’s xenon light array provides a bright, stable strobe light over a wide measurement range. The ST-328 arrays are available in several standard sizes from 10” (260 mm) to 71” (1800 mm) in length. Custom sizes are available upon request. The arrays are easily mountable on production equipment. An optional mounting adapter kit is available to aid in array installation. An integral or remote control enclosure is available to program the unit. If selecting the separate, external control enclosure, communication is via a 9.8’ (3 m) connecting cable. Operation is simple with the 6 button keypad and large, LED display. Flash rate is quickly adjustable via the control dial. The unit can work off user programmed flash frequency or from a remote sensor’s signal which will automatically adjust to corresponding process fluctuations.

The ST-328 is designed for speed and frequency measurements in the printing, packaging, textile, automotive, cable, mining, steel, chemical, optical, medical and shipbuilding industries in various applications.
