"You won't see any 'signs' unless you measure above 10kHz" - The reason bearing abnormalities manifest at high frequencies.

Did you know that abnormalities in the bearings of rotating machinery actually appear most quickly in the high-frequency range above 10 kHz? Despite signs appearing 3 to 6 months before a failure, many sites are unable to measure these signals. This document clearly explains the necessity of high-frequency measurements from both the perspective of actual measurement data and diagnostic techniques.

basic information

■ Wireless vibration sensor that does not require wiring work - It uses a battery-operated wireless sensor, eliminating the need for wiring. ■ Automatic measurement once a day for near-continuous monitoring - Since measurements are taken automatically and regularly, manual measurement work is not required. ■ Can be retrofitted, ideal for small-scale starts - Easy to expand retroactively, allowing for reduced initial costs. ■ High-frequency response (17kHz) detects early abnormalities in bearings - Early abnormalities in bearings often appear in the high-frequency range, which is why we focus on high-frequency response. ■ Long battery life design of approximately 5 years - Despite being a compact sensor, it ensures battery life. ■ Easy operation and diagnosis through a dedicated app - Provides visualization of equipment status and abnormal diagnosis. ■ Technical support by our "certified vibration diagnosis professionals" - One-stop support from consideration of introduction to aftercare, compliant with ISO 18436-2 for mechanical condition monitoring diagnostic technicians (vibration).
