Description

Stroboscope Non Contact Tachometer Rotational Speed Tester 60-40000RPM/FPM
I . Introduction:
The stroboscope is a rotational speed measuring instrument that makes use of the persistence of vision (when the light source flashing at the set frequency is synchronized with the rotational speed of the object, a relatively static visual persistence phenomenon occurs). When observing an object rotating at a high speed or moving, by adjusting its flickering frequency to be close to and synchronizing with the rotation or moving speed of the measuring object, the measured object looks be moving slowly or static although moving at a high speed, this optical phenomenon of persistence of vision makes it easy to observe the motion of high-speed moving objects with the naked eyes. In this way, it is possible to measure the rotational speed of various types of rotating objects without contact, as well as to detect the motion state and surface defects of the object. Its application is very wide, such as various types of rotors, gear meshing, vibration equipment diagnostics, textile, printing,
production lines and other high-speed rotating object surface defects and motion trajectories.
II. Performance features:
* The advanced technologies such as micro-computer technology (CPU), software frequency generator and
anti-jamming technology are applied to conduct non-contact measurement of rotation speed, as well as to inspect the status of moving objects and detect defects on the surface.
* Large LCD with backlight ensures clear readings and no parallax.
* Two adjustment ways: single-step adjustment (coarse/fine adjustment) and continuous adjustment (coarse/fine
adjustment) for easy measurement.
* With data storage function, it can store 10 commonly used stroboscopic data, which can be called up at any time, very convenient and quick.
* There are special backlight and flash control switches, saving battery power.
* The power supply uses four AA 3.7V lithium-ion rechargeable batteries (14500) to ensure long-lasting power. When the voltage is lower than the specified voltage, it will automatically prompt.
* 60 high-brightness LED flash heads, double the brightness and more convenient to use (observe).
* The structure is sturdy and exquisite. The whole machine adopts durable and high quality electronic components. The outer casing is made of light weight and hard ABS+PC engineering plastic. It has beautiful appearance, convenient carrying and simple operation.
