The PCE-LES 103: for non-contact measurement of rotational speed
Stroboscopes are often used for rotating or vibrating objects to determine rotational speed or vibration frequency. Typical areas of application include rotating industrial machinery, fans in air-conditioning and ventilation systems.
PCE Instruments has developed a new stroboscope, the PCE-LES 103. This state-of-the-art device enables precise measurements and inspections in various industrial applications. The PCE-LES 103 stroboscope features three powerful high-power LEDs that provide an impressive light intensity of 6160 lux at 30 cm and 1000 Hz. With its digital pulse width modulation and phase shift of -360° to +360°, the compact stroboscope guarantees extremely precise control of the light pulses.
The PCE-LES 103 stroboscope offers flexible application options thanks to its adjustable flash frequency in FPM (flashes per minute) and Hz, for example for the visual inspection of materials (textiles, coatings), non-destructive testing (NDT) and troubleshooting in high-speed automation processes using virtual slow motion. With a frequency measurement range of 60 to 300,000 FPM or 1 to 5000 Hz and a high accuracy of 0.003 % or ±1 LSD, it is ideal for testing ink densities and curing quality, making it an indispensable tool for professionals.
The intuitive operation of the device is a particular benefit. The clear 2.8-inch TFT colour display makes it easy to navigate through the menus, which are available in ten languages, including English, German, Spanish and French. The flash frequency can be quickly and easily adjusted using the x2 and ÷2 keys, allowing for rapid adaptation to different requirements.
The stroboscope also offers a long operating time of 4.5 hours at a flash frequency of 100 Hz and a display brightness of 70 %. The automatic power off can be set to between two and ten minutes and can be deactivated if necessary to ensure continuous use.
PCE Instruments has designed the PCE-LES 103 to be rugged, with an IP52 rating and to operate in a wide temperature range of -20 to 60 °C. Power is supplied via a 5 V DC, 2 A adaptor and the built-in lithium-ion battery with a capacity of 2200 mAh and a voltage of 7.4 V ensures a reliable power supply.
The PCE-LES 103 is also available in two UV versions – PCE-LES 103UV-365 and PCE-LES 103UV-385. The UV stroboscope PCE-LES 103 UV-365 covers a UV light range from 365 to 370 nm and the PCE-LES 103UV-385 covers a range from 370 to 385 nm. These UV stroboscopes are used, for example, to inspect printing webs during the production of pharmaceutical packaging and documents with security features (ID cards, banknotes, barcodes with invisible ink) that only become visible under UV light.
To summarise, the PCE-LES 103 series stroboscopes from PCE Instruments offer a combination of high performance, precision and ease of use that makes them indispensable testing tools for professionals in industry and research.
