Stroboscope
High performance hand-held stroboscope for machine inspections
The SKF TKRS 41 is designed for general maintenance tasks and with its standard operating mode is streamlined for fast and straightforward usage. The professional mode can be activated for more demanding applications, for example when enhanced input signal modification is needed to trigger the stroboscope with machine signals. For convenience, the “SLOW” function can be used to examine all parts of the rotating machine in slow-motion.
High brightness & operating time – Powerful array of 118 LEDs delivering up to 8 000 lux of luminescence for usage in almost any environment
Slow mode – Frozen images rotate in slow motion and support convenient inspection
Portable and sturdy – Lightweight aluminium housing with integrated battery and rubber bumper strips for use in industrial environments
Easy operation – Ergonomic and intuitive controls allow quick setting of the correct flash rate
Automatic laser synch – Build-in laser speed measurement, with automatic synchronization of the flash rate, eliminates the need to search for the right frequency
Professional input signal modulation – Machine input signals can be used and modulated to trigger the stroboscope
Typical applications
The SKF TKRS 41 is a portable, high-performance stroboscope for visual inspections. It is suitable for general maintenance in challenging industrial environments and the input trigger can be used for advanced inspections in production processes and testing equipment.
General maintenance – Inspection of running machines for visible damages, such as fan blades, shafts, couplings, belts, chains, gears, etc.
Paper production – Setup and control of paper production quality during operation
Textile industry – Installation and inspection of production processes such as spindles or weaving patterns
Printing industry – Check of printing quality during production
Test equipment – Analysis of materials and components during fast movements such as analysis of resonance behaviour
