| Acoustic Emission | Acoustic emission instruments and fault detectors are used to detect changes and monitor conditions in mechanical, electrical and process systems. Fault detectors can pick up changes in bearings, gearboxes or other rotating machinery due to wear or load changes. Fault detectors are also useful for detection of leaks or changes in process component such steam traps, piping, valves or pressure vessels. Shorting, corona discharges or arcing in electrical power distribution system can also be detected using acoustic detection instruments. Faults or features within a mechanical system provide specific acoustic or vibrational responses. If a break, deformation or other failure occurs in a piece of equipment, sensitive acoustic emission sensors can detect the high frequency burst given off during the event. Monitoring acoustic emissions can also access the location and severity of a fault. The acoustic emission technique is particularly useful in determining the structural adequacy of tanks and pressure vessels. | ||
| Condition Monitor / Fault Detector | Condition monitors and fault detectors measure and record critical parameters and find faults in electrical, mechanical, optical or other systems. For example, in an electrical system, an arching circuit breaker is a type of fault. In a mechanical system, a failed roller bearing is a type of fault. Both mechanical and electrical faults produce characteristic sounds, which fault detectors discover by using air or structure-borne acoustic detection techniques. | ||
| Flaw Detector | Flaw detectors are instrument or systems that detect and measure flaws in materials. | ||
| Corrosion Instrument | Corrosion instruments measure or monitor corrosion. | ||
| Leak Detector | Packaging defect and leak detection instruments are suitable for detecting holes, leaks, cracks, defective seals, channel leaks, contaminated materials, missing product or closures. | ||
| Material Condition Tester | Material condition testers evaluate material properties or conditions such as hardness, residual stress, strength, modulus or density. | ||

| Form Factor: | |||
| Your choices are... | |||
| Bench / Rack / Cabinet | Devices sit atop a bench or desktop, or are mounted in a rack or cabinet. | ||
| Crawler | NDT crawlers and scanners are inspection tools that automatically travel down pipelines or up tank walls while scanning nondestructive probes. Also, a device that moves a probe across a surface to map flaws or thickness variations such as a tank bottom scanner. Scanners, crawlers or trackers are used in regions too small, long or dangerous for an operator to access or navigate manually. | ||
| Monitoring System | Devices are monitors or monitoring systems used to continuously detect or measure flaws, thickness or corrosion. | ||
| Portable / Hand Held / Mobile | Devices are portable, handheld or mobile. | ||
| Other | Other unlisted or proprietary form factors. | ||

| Air / Structure Borne? |
Air and structure-borne detection methods find faults in electrical and mechanical systems based on the detection of acoustic signals. These signals can be airborne, travel through the air or reside only within a solid structure or mechanical system. There are many applications for air or structure-borne ultrasonic detection or inspection methods.
| ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Electromagnetic Acoustic Resonance? | Electromagnetic acoustic resonance (EMAR) uses a non-contact electromagnetic transducer to impart a signal for resonant acoustic analysis. The non-contact, EM-induced signal produces a pure resonant response. Mechanical vibration from surrounding machinery does not influence the ultrasonic signals in the materials or parts being inspected. Localized or wide acoustic fields can be generated, depending what features need to be isolated and measured. Small surface or subsurface flaws or anomalies can also be isolated. Specifically, the entire part can be resonated for elastic stiffness and structural integrity assessments. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Digital Imaging System? | Digital imaging and tomography systems create 3D images of patients or products by capturing 2D cross-sectional images and applying mathematical or computed reconstruction techniques. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
