Description

The GI150/5 is a piezoelectric Acoustic Emission sensor engineered for detecting transient stress waves generated by crack propagation, friction, or material deformation in metallic structures. Its integral 26dB preamplifier provides immediate signal amplification, outputting a conditioned signal compatible with standard 5V data acquisition systems and industrial PLCs, reducing external noise pickup.

Constructed with a full SUS-304 stainless steel body and a ceramic sensing face, the sensor delivers high mechanical durability and consistent sensitivity (>73dB) across an operating temperature range of -20°C to +60°C. The IP62-rated enclosure protects against dust ingress and light moisture, making it suitable for monitoring pipelines, pressure vessels, bridges, and rotating machinery in oil & gas, chemical, and power generation facilities.

Key Features

  • Certified intrinsically safe design for operation in explosive atmospheres
  • Integrated 26dB preamplifier powered by a single 5V DC supply
  • High sensitivity peak >75dB for precise detection of micro-cracks and partial discharges
  • All-welded SUS-304 stainless steel housing ensures long-term corrosion resistance
  • Wide frequency response from 60 kHz to 400 kHz captures a broad range of acoustic events
  • IP62 protection rating defends against dust and limited water spray
  • Lightweight 48g construction with SMA connector simplifies field installation
  • Includes a dedicated hold-down saddle mount for secure mechanical coupling

Applications

  • Continuous structural health monitoring (SHM) of pipelines, pressure vessels, and storage tanks
  • Early crack detection and fatigue monitoring in bridges, wind turbine blades, and aerospace components
  • Partial discharge (PD) detection and insulation fault monitoring in high-voltage electrical equipment
  • Process monitoring and leak detection in hazardous environments within oil, gas, and chemical plants
  • Machinery condition monitoring for bearings, gears, and pumps to predict mechanical failures

Frequently Asked Questions

What is the operating voltage for the built-in preamplifier?

The integrated 26dB preamplifier requires a single 5V DC power supply. This voltage powers both the sensor's piezoelectric element and the amplifier circuitry, providing a conditioned output signal ready for acquisition by data loggers, PLCs, or industrial monitoring systems.

How is the sensor mounted for optimal acoustic coupling?

For optimal performance, the sensor must be securely mounted using the included hold-down saddle mount to ensure consistent mechanical coupling to the test surface. Proper surface preparation (cleaning, possibly light grinding) and the use of a suitable acoustic couplant (e.g., grease or epoxy) are critical for efficient transmission of acoustic waves into the sensor.

Can this sensor be used in hazardous or explosive environments?

Yes, the GI150/5 is specifically designed and certified as intrinsically safe (IS) for operation in hazardous areas classified as explosive atmospheres. Its design limits electrical and thermal energy to levels below what is required to ignite a specific hazardous gas mixture, making it safe for use in oil & gas, chemical, and mining applications.

What type of cable is recommended for connecting the sensor?

The package includes a low-noise, flexible coaxial signal cable (RG178 or RG316). For extended runs or environments with high electromagnetic interference (EMI), it is recommended to use high-quality, shielded coaxial cables with proper grounding to maintain signal integrity and minimize noise pickup.
