DT-2239A Digital Stroboscope Product ID: DT-2239A
DT-2239A
Digital Stroboscope
The model DT-2239A is a microprocessor circuit design, high accuracy, digital readout, light duty STROBOSCOPE/TACHOMETER that is ideal for inspecting and measuring the speed of moving gears, fans, centrifuges, pumps, motors and other equipment used in general industrial maintenance, production, quality control, laboratories and as well as for schools and colleges for demonstrating strobe action.
Features:
The digital stroboscope measures the speed by simply aiming the beam to the object, adjusting and synchronizing the flash rate such that a still picture is seen. The xenon lamp is very bright to allow room light operation at long distance. Ideal for checking rotating fan, motor, pump, conveyer and robot. Used widely in auto and fan maintenance, production, packaging and laboratory

The stroboscopic principle, also known as the flash synchro-tachometer principle, is a method used to measure whether a continuously cyclically moving object is slowly moving or fixed. The principle is used to study objects that rotate, reciprocate, oscillate or vibrate. The rotation of mechanical parts and rotating body objects such as vane fan motors are common examples of observations. The simplest form of observation is to adjust the speed of the stroboscopic meter using a rotating disk with evenly spaced holes placed in insight between the observer and the rotating target. The speed is adjusted so that it becomes synchronized with the motion observation system, which can be slowed down or stopped. Illusions are the persistence of vision due to differences in time, often referred to as the flicker effect. The light emission of the stroboscope can be easily and quickly controlled by adjusting the variable resistor. Make the flash frequency adjusted so that it is a cycle speed equal to or a unit counts lower or higher than the object's cycle speed, at which point objects that rotate the object will all be seen as stationary in sync, or moving or forward or backward, depending on the flash's frequency.
