Condition Monitoring Stroboscope

Condition Monitoring Stroboscope PCE-LES 303UV-385

SKU : PCE-LES 303UV-385
Category : Stroboscopes

Analysing the movement of rotating machines is quick and easy with our stroboscope. The Condition Monitoring Stroboscope is equipped with 3 high-power UVA LEDs, which together generate a light intensity of 317 μW/cm² at a distance of 30 cm. The Condition Monitoring Stroboscope allows you to set the flash frequency in both FPM and Hz. The Condition Monitoring Stroboscope is pocket-sized and also mains-independent thanks to the rechargeable battery.

Analysing the movement of rotating machines is quick and easy with our stroboscope. The Condition Monitoring Stroboscope is equipped with 3 high-power UVA LEDs, which together generate a light intensity of 317 μW/cm² at a distance of 30 cm. The Condition Monitoring Stroboscope allows you to set the flash frequency in both FPM and Hz. The Condition Monitoring Stroboscope is pocket-sized and also mains-independent thanks to the rechargeable battery.

The Condition Monitoring Stroboscope is operated intuitively using the 10 keys, allowing quick adjustments to be made. The phase shift allows the observation point to be moved variably. The pulse width can be used to set the duration and therefore also the intensity of the flash frequency. The display brightness can be selected in the settings menu, as can switching off the display after a period of inactivity, which extends the battery life. The Condition Monitoring Stroboscope is supplied with a USB-C charging cable in a service bag.

When input trigger mode is activated, the device synchronises the flash frequency of the LEDs based on the input trigger signal provided (or with the output trigger signal). A rising or falling edge of the signal to be synchronised can be selected. In output trigger mode, the Condition Monitoring Stroboscope generates a PWM signal with the selected frequency, the selected duty cycle and the selected phase shift.

Route measurement mode allows you to use a number of predefined settings for frequency, duty cycle and phase shift and navigate from one point to the next without having to manually set the values at each point. The device allows the storage of up to 15 routes with a maximum of 10 machines per route and a maximum of 5 points per machine.

Condition Monitoring Stroboscopes are indispensable tools for monitoring and inspecting production facilities, e.g. in the printing and textile industries but also for general maintenance and inspection tasks in all industrial sectors. They also enable non-contact speed and vibration measurement: if the flash frequency of the Condition Monitoring Stroboscope matches the movement frequency, the measured object appears stationary.
