Description

The QAWRUMS W500/1 is a wideband passive piezoelectric Acoustic Emission sensor engineered for precise detection of transient stress waves generated by micro-cracks, impacts, friction, and material deformation. Its core piezoelectric element, coupled to a ceramic face, provides a flat frequency response centered around 500 kHz, ensuring high-fidelity signal capture for frequency-domain analysis.

Housed in a durable SUS-304 stainless steel case with an IP68 environmental seal, the sensor is built to withstand demanding conditions, including exposure to moisture, dust, and extreme temperatures from -20°C to 120°C. This robust construction makes it suitable for permanent installation on critical infrastructure such as pressure vessels, pipelines, rotating machinery, and composite structures for continuous health monitoring.

Key Features

Passive piezoelectric design ensures stable, low-noise operation without requiring an external power supply.
High sensitivity (>65dB) enables detection of subtle acoustic emission events indicative of early-stage material failure.
Rugged SUS-304 stainless steel housing and IP68 rating provide exceptional durability and environmental protection.
Ceramic sensing interface offers optimal acoustic impedance matching for efficient energy transfer from the test structure.
Wide operating temperature range (-20°C to 120°C) supports deployment in diverse industrial and outdoor settings.
Integral 1.2-meter coaxial cable with BNC connector simplifies installation and connection to data acquisition systems.
Optimized for Non-Destructive Testing (NDT), structural health monitoring (SHM), and materials research applications.

Applications

Continuous structural health monitoring (SHM) of bridges, wind turbine blades, and pressure vessels.
Non-Destructive Testing (NDT) for crack detection and leak location in pipelines and storage tanks.
Machinery condition monitoring to detect bearing faults, gear mesh issues, and cavitation in pumps.
Materials research and composite structure testing to study failure modes and acoustic emission signatures.
Laboratory analysis of surface displacement and frequency response in mechanical components.

Frequently Asked Questions

Does the QAWRUMS W500/1 sensor require external power?

No, the W500/1 is a passive piezoelectric sensor. It does not require an external power supply. The piezoelectric element generates a voltage signal directly in response to mechanical stress waves (acoustic emissions). This signal is output via the BNC connector to an external data acquisition system or preamplifier.

What is the recommended mounting method for this AE sensor?

For optimal acoustic coupling, the sensor should be mounted directly onto the test surface using a suitable couplant (e.g., grease, epoxy). The flat ceramic face ensures good contact. For temporary setups, a magnetic hold-down can be used. Ensure the mounting surface is clean and smooth to maximize signal transmission and sensitivity.

What type of data acquisition system is compatible with the W500/1's BNC output?

The sensor's BNC output is compatible with any data acquisition (DAQ) system, oscilloscope, or acoustic emission analyzer featuring a standard BNC input. Since the sensor is passive, the connected system must provide appropriate input impedance (typically 50 ohms or 1 MΩ) and sufficient gain to condition the typically low-level AE signals for analysis.

Can this sensor operate in high-temperature or wet environments?

Yes. The W500/1 is housed in SUS-304 stainless steel with an IP68 waterproof rating, making it resistant to dust and prolonged immersion. Its specified operating temperature range is -20°C to 120°C, allowing for deployment in many harsh industrial, outdoor, or process monitoring environments.
