The Shimpo ST-5100 is a portable, light-weight stroboscope with trigger light activation that utilizes 21 super bright CREE High Powered LED lamps. The ST-5100's LED array provides a bright, stable strobe light over a wide measurement range with a lifetime far exceeding xenon-lit stroboscopes. Unique to the ST-5100 is an auto-speed detection laser that translates speed sensed directly over to the flash rate of the LED's, simplifying operation. Containing a rechargeable lithium battery, a single charge is able to last up to a full 5 hours of operation. The ST-5100 is designed for speed and frequency measurements in motion and vibration analysis applications. It is ideal for predictive and preventive maintenance applications such as: motors; shafts; roto-gravure printing; extruders; blow molding; wire lettering and striping; engraving; pulse jets; water jets; fans; cams; gear teeth; belt inspections; fuel injectors; vibration analysis; audio speaker analysis; spindle spinning; cutting blade timing and sharpness; plus many more in the printing, packaging, textile, automotive, cable, mining, steel, chemical, optical, medical and shipbuilding industries.
