"Abnormal noise detection is possible just by registering normal sounds and vibrations" Abnormal Noise Checker
"From unstable sensory testing to quantified stable testing" Achieving setting-free and low-cost solutions by specializing in pass/fail judgment!
Unlike conventional multifunctional analysis devices, we have achieved a setting-free and low-cost solution by specializing in pass/fail judgment. By simply registering normal sounds and vibrations as master data, it is possible to determine abnormal sounds. (The threshold for judgment can be set arbitrarily.) 【What the Abnormal Sound Checker Can Do】 - Inspection of motor dents and fluctuating sounds - Detection of abnormal sounds and vibrations in gears and bearings - Can be integrated into existing devices 【Features】 (1) Easy Operation - Abnormal sound judgment is possible by simply registering normal sounds and vibrations as master data. * In practice, confirmation of sound and vibration data is necessary. (2) Traceability - Inspection data can be saved to a USB memory. - Data can be transferred to external devices via Ethernet. (3) Inline Compatibility - Equipped with general-purpose input/output for trigger signal input and judgment result output. (4) Low Cost - Achieved low cost by narrowing down functions. - Can be integrated into existing devices.
