Fluke 820-2 Strobe Light
Determining the speed of rotating equipment can be difficult, but the Fluke 820-2 LED Stroboscope simplifies the process by allowing you to diagnose the stopping mechanism without actually stopping or touching the machine. Whether you are trying to diagnose oscillations, slippage, or unwanted distortion, the 820-2 LED Stroboscope is the perfect modern tool for troubleshooting, process or product research, or new developments.
The Fluke 820-2 Stroboscope is a digital LED tool for diagnosing moving mechanical parts. It works on the basis of the strobe effect, which creates a visual illusion that the observed rotating object is stationary with intermittent flashes of light. As a source of pulsating light, the stroboscope uses a flash lamp consisting of seven LEDs that create a light stream with a high intensity.
Applications of the Fluke 820-2 are effective in such areas as: Determining the speed or frequency of rotating machinery without stopping or touching it. Detection of parasitic oscillations, various defects, distortions or slippage. Determination of factory serial numbers or other markings on fast-moving parts. Using the Fluke 820-2 stroboscope for diagnostics without contact with the object, you can in many cases replace a laser tachometer, which requires a reflective strip to be attached to the rotating part. The main settings of the Fluke 820-2 are made using the SETUP mode, which is activated by pressing a button. It is not necessary to calibrate the tachometer: you can work with factory settings. However, independent pulse generation allows you to take into account the features of the objects of study and their motion characteristics when measuring. In this case, in the settings of the Fluke 820-2 stroboscope, you can select the required number of flashes, the frequency of which can vary from 30 to 300,000 per minute, set the pulse width in microseconds and degrees, pulse delay, phase angle degree, external pulse divider coefficient, external trigger front. The multi-level liquid crystal display, designed for 6 digits, allows you to display a large amount of information, facilitating the process of setting up the Fluke 820-2. During the measurement, the results are displayed in digital form in the main area of the screen. The display also shows the battery charge level, when it decreases, the device notifies the operator of the need to replace the power source. The flash frequency can be changed without entering SETUP, synchronizing it with the rotation frequency of the object using the "×2 and ÷2" button system. Equipped with an ergonomic case, the Fluke 820-2 fits comfortably in the hand. By directing a stream of pulsed light from an LED lamp to an object, you can observe the measurement results on a display located on the other side of the light source. It is worth buying a Fluke 820-2 strobe light, the price of which fully corresponds to its characteristics, if in your work you have to diagnose various malfunctions in the operation of mechanisms, the downtime of which is undesirable.
