Manual stroboscopes RT-Strobe Pocket LED
Applications:
Determination and testing of the speed of rotation or frequency of vibrations of the rotating or
vibrating systems without interrupting the production process. At places difficult to access, particularly
sensitive systems, as well as for recognising unwanted vibration resonances. Suitable for inspection
of motors, turbines, pumps, fans, centrifuges, paper and film manufacturing, vibrating table, shaking and
vibrating sieves.
Principle of measurement: the stroboscope works with infinitely variable light frequency. For testing, it
is aimed at the object and the flashing frequency is adjusted by pressing the control keys. If the flashing
frequency of the stroboscope matches the frequency of the test object, it appears as if it were not moving.
The frequency displayed is equal to the speed of rotation of the object.
Execution: device with state-of-the-art LED technology and great light intensity throughout its frequency
range, with multiple line LCD display, high setting accuracy and stability. Pressing the (M) key calls up the
setting menu in which the user sets the flash duration in microseconds or degrees, and the delay time
between the internal trigger signal and the flash in milliseconds or degrees.
