As automation advances in production equipment abnormalities and product inspections, "visual" judgments using X-rays and images are generally well-known. However, the "sensory inspection" methods, such as auditory and tactile assessments—traditionally performed by skilled technicians—based on "sound and vibration" seem to be less recognized. At Elmek, which has over 40 years of experience in the automation and development of judgment systems based on "sound and vibration," we offer measurement and judgment systems that can accommodate various cases, utilizing our analytical know-how built on extensive experience and years of technology. 【Case Examples】 - Production Equipment Abnormality Monitoring: Detecting abnormalities in real-time, 24/7 - Smart Audit Device IoT: Automatic notification to responsible personnel when an anomaly occurs - Meat Processing Hard Bone Inclusion Detection: Hard bones during meat processing can be detected through sound and vibration - Engine Comprehensive NVH Judgment: A trusted system used worldwide - AI Sound and Vibration Judgment System: Easy recording with a newly developed impact sound inspection tool, with AI sound and vibration judgment on-site If you review our catalog and find it helpful for solving your challenges, please feel free to contact us for inquiries or consultations.

• Non-destructive testing

Sound testing and product shipment inspection (for cracks and fissures), which have relied on the sensory judgments of skilled workers and simple machines, can now be automatically and more accurately assessed by AI. This eliminates the risk of human judgment, enhances work efficiency, improves productivity, addresses labor shortages, and reduces costs. Additionally, by combining this with the sound testing device developed by our company, it is possible to collect reproducible data without variation, regardless of who operates it. Furthermore, as the AI learns from the image pattern data of past good and defective products through deep learning algorithms, the accuracy of the assessments improves, enabling advanced judgments that surpass human recognition capabilities. We also offer "custom" systems tailored to various measurement needs of our customers, both hardware and software, so please feel free to consult or inquire with us. 【Measurement Examples】 ■ Product shipment sound testing ■ Infrastructure maintenance non-destructive testing ■ Medical and physiological analysis and research ECG analysis / fracture assessment, etc. *For more details, please refer to the PDF materials or feel free to contact us.

The "Smart Monitoring Device (Constant Abnormality Monitoring System)" continuously monitors important production equipment to prevent the occurrence of defective products due to equipment abnormalities. It captures changes in sound and vibration, sending alerts to the control device, the room's PC, and mobile phones. Once notified, you can easily verify the abnormal sound by ear with simple operations. The issued alerts are recorded in the alarm log with timestamps, with minor alerts displayed in orange and major alerts in red. 【Features】 ■ Constantly monitors production equipment abnormalities through sound and vibration ■ Effective in sensory inspections ■ Trend viewer displays long-term changes ■ Issues alerts categorized as minor and major ■ Sends control signals to PLC and notifies via email to PC and mobile *For more details, please refer to the PDF document or feel free to contact us.

We will introduce a case study of a measurement system. This is a system that monitors the structure of a ship's hull. It regularly measures data such as vibrations of the ship while sailing, adding GPS location data, and keeps a history of the ship's condition and location information. It can be used for maintenance inspections of the ship's motor and other components. *For more details, please refer to the related links page or feel free to contact us.

The outer circumference of railway vehicle wheels is fitted with iron tires, but when emergency brakes are applied and the wheels stop rotating while sliding on the rails, part of the tire becomes flat due to friction. When there is a flat spot, a vibration occurs with a "thud" each time the wheel rotates, resulting in a very uncomfortable ride. The "Wheel Flat Detection" system detects this during the passage of the train and reports it to the center. 【Basic Configuration of the Product】 ■ EC2320: USB AD Converter ■ Computer: Windows 10 ■ Input Box: ELMEC manufactured ■ Vehicle Detection Sensor Input Circuit: 3 channels ■ Acceleration Sensor: 4 channels ■ Charge Amplifier: 4 channels ■ Flat Detection Software: Custom Software *For more details, please refer to the related link page or feel free to contact us.

How do you determine the wear of bearings and gears in rotating machines? It goes without saying that sudden failures of servos and gears in robots and other machinery must be absolutely avoided. Early replacement of parts is essential for improving work efficiency and reducing costs. We recognize and analyze patterns that deviate from the normal vibration pattern of steady-state conditions and issue alarms. Our company is committed to preventive maintenance through this approach. [Features] - Automation of deterioration assessment of gear components using grease methods and sound analysis - Compatibility with low-volume, high-variety production systems - Extension of operational time by estimating the rise of the bathtub curve - Analysis and assessment using 1/3 octave analysis and wavelet analysis according to the target *For more details, please refer to the PDF document or feel free to contact us.

This document introduces examples of measurement systems that determine the presence of hard bone contamination in meat products. In many meat processing centers, all meat is inspected using soft X-rays to check for the presence of bone fragments. However, if bone fragments are embedded within fat, they cannot be distinguished. Our analysis shows that when bone fragments are sliced with a meat slicer, a specific frequency range (sound/vibration) changes. By attaching a vibration sensor to the bearing section of the rotating blade, we can capture this slight change in vibration and determine the presence of bone fragments through FFT 1/3 octave analysis.

The system converts sound and vibration data recorded by a tapping device into a single color image classified by frequency, time, and intensity using a proprietary auto-wavelet. By applying deep learning to this, it enables automatic judgment of sound and vibration AI. In the system, by initially training it with healthy and multiple unhealthy data, it can automatically classify as healthy, unhealthy 1, unhealthy 2, and make OK/NG judgments. Additionally, we also offer simple machine learning (ML) AI. 【Overview】 ■Issues - Variability among individuals - Time-consuming data sharing, organization, and analysis ■Solutions - Accurate judgments without variability - Easy data sharing, organization, and analysis through PC processing *For more details, please refer to the PDF materials or feel free to contact us.

The characteristics of sound and vibration that were not visible in conventional waveform data are converted into a "color image on the time axis that shows specific frequencies and sound pressure levels" using our unique analysis method. This technique enables spectral analysis of sudden and non-stationary acoustic and vibrational changes over time, making it useful for phenomenon analysis and research in various fields. Additionally, beyond visual judgment, combining this with our AI image recognition system allows for automatic judgment, which was difficult with FFT analysis and octave analysis. 【Measurement Examples】 Product shipment impact sound inspection (cracks, fractures) Impact sound inspection of concrete and exterior walls in infrastructure Noise analysis due to aging deterioration of gearboxes Impact sound analysis of golf balls for research and development Crack detection in semiconductors Medical and physiological applications (ECG, fracture detection), etc. 【Features】 ■ Visualization of sound and vibration ■ Possible visual judgment ■ Automatic judgment possible in combination with AI image recognition system ■ Usable for analysis and research in various fields *For more details, please refer to the PDF document or feel free to contact us.
