DT-366 Stroboscopes

Series DT-366 LED Stroboscope

The DT-366 is a portable, battery-powered stroboscope that utilizes super bright CREE High-Powered LED lamps. The DT-366’s LED array provides a bright, stable strobe light over a wide measurement range with a lifetime far exceeding xenon-lit stroboscopes. Combined with large, backlit LCD display, operation is simple with the 8 button keypad and quick rate-adjustment dial. Phase shift, flash duration, plus flash rate all are easily viewed and adjustable. The unit can function by user altered flash frequency or from a remote sensor’s signal input which will automatically adjust the stroboscope to the corresponding process fluctuations. Containing a rechargeable lithium battery, a single charge is able to last up to a full 12 hours of operation.

The DT-366 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, 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.

  • LED technology greatly extends operation life and eliminates need to replace burned out bulbs
  • Backlit LCD display aids usage while operating in dimly lit areas
  • Easy adjustment with flash dial combined with x2/÷2 and fine tuning +/- buttons enables precise flash setting
  • Fast-charge rechargeable battery provides exceptional, long-term usage reliability
  • Adjustable Flash Pulse duration achieves sharper images for detailed inspection
  • Phase shift (in degrees of delay time) enables visual analysis of rotating or reciprocating objects through all points of motion/time/angle
  • Flash rate may be synchronized with process speed with input from sensor or controller
  • 1/4-20 UNC connection for permanent mount applications (remove trigger handle)
