The function of the stroboscope

A stroboscope, also known as a strobe still or tachometer, strobe light, etc., can emit brief and frequent flashes of light. Adjust the flashing frequency of the stroboscope so that it is close to (or synchronized with) the rotational (or motion) speed of the object being tested. Although the object is moving at high speed, it appears to be moving slowly or relatively stationary. By utilizing this visual persistence phenomenon, the human eye can easily observe the surface quality and operating conditions of the high-speed moving object, and the flashing frequency of the stroboscope is the rotational speed or motion frequency of the object being tested (such as a motor). It is also possible to use a stroboscope to analyze object vibration, observe the movements of high-speed moving objects, and take high-speed photographs.

The duration of the flash of the strobe and the relative brightness of the light will affect the clarity of the image. The longer the duration of the flash, the more blurry the image.

It is recommended that the flash brightness of the stroboscope be about 4 times the brightness of the surrounding environment.

2.1 OverviewPT-L02C High Brightness Fixed LED Strobe for Printing Machine

The PT-L02C LED fixed strobe is a new generation of new energy strobe developed by our company. Internally, high-performance microcomputer processing units and efficient program processing methods are used to achieve high-precision flicker; Using LCD screen to display data, human-computer interaction is more convenient and intuitive; Adopting efficient energy conversion chips, the energy output is more stable and reliable; Using imported LED chips, it has the characteristics of environmental protection, long service life, high brightness, and low overall heat generation; Adopting an array style LED bead arrangement, the brightness is high and uniform.

This stroboscope is suitable for industries such as printing, papermaking, textile, steel cold rolling, large generators, aluminum foil, and machinery manufacturing.

2.3 Main technical indicators

• Working power supply: AC220V~240V, 50-60Hz
• Trigger frequency range: 50.0 times/minute to 24000.0timesAdjust the accuracy 0.1 times per minute

1.00Hz ~ 400.00Hz， Adjustment accuracy 0.01Hz

• Strobe accuracy: ± 0.01%;
• Frequency display: LCD display screen
• Working mode: internal triggering and four external triggering modes
• Adjustable strobe units: f/m, Hz, m/min

• Internal triggering method

  The internal triggering method refers to the provision of a strobe signal inside the strobe, which can be controlled by adjusting the flashing frequency through the buttons located on the strobe control panel.

  3.2 External triggering mode

  The external triggering working mode is provided by external sensors such as photoelectric eyes, Hall switches/proximity switches, photoelectric encoders, gear sensors, etc. The stroboscope flashes according to the frequency of the signal to achieve automatic tracking function. External triggering modesingle pulse、Zhou Changbiao、encoder、gearFour ways of working.

  insingle pulseIn working mode, the stroboscope flashes once it detects an external signal, usually when the frequency of the printed pattern motion is consistent with the frequency of the signal detected by the sensor. For example, using a color code sensor (photoelectric eye) to detect the color code of printed patterns. After passing through each pattern, the sensor detects a signal and the strobe flashes once to achieve automatic tracking.

  When the signal detected by the strobe is not consistent with the operating frequency of the pattern, it can be selected according to the different connected sensorsZhou Changbiao、encoderandgearpattern.
