Description

The GH150 Acoustic Emission Sensor utilizes a piezoelectric sensing element housed in a stainless Invar steel body with a ceramic face, engineered for minimal thermal expansion and high mechanical integrity. Its wide frequency response captures a broad spectrum of acoustic emission events, from low-frequency crack propagation to high-frequency leak signals, making it suitable for precise fault detection.

Designed for permanent installation in harsh industrial settings, the sensor features a built-in magnetic base for secure mounting on ferromagnetic surfaces and an IP68 protection rating against dust and water ingress. The integrated 3-meter cable simplifies routing in high-temperature zones, such as those found in power generation, petrochemical, and heavy manufacturing facilities.

Key Features

  • Engineered for continuous operation in environments from -45°C to +600°C
  • Constructed from thermally stable stainless Invar steel and a durable ceramic sensing face
  • Delivers high sensitivity (>60dB) across a 50 kHz to 600 kHz frequency band
  • IP68-rated enclosure ensures reliable performance in dusty, wet, or corrosive conditions
  • Integrated 3-meter high-temperature cable and BNC connector for straightforward system integration
  • Built-in magnetic base facilitates quick and secure mounting on steel structures
  • Optimized for use with standard PAS/PAV series acoustic emission preamplifiers
  • High-value build for critical industrial monitoring applications

Applications

  • Continuous acoustic emission monitoring in high-temperature pipelines and pressure vessels
  • Structural health and crack detection in industrial furnaces, reactors, and boilers
  • Fault and leak detection in power plant steam lines and turbine components
  • Condition monitoring of high-temperature processing equipment in petrochemical and steel plants
  • Integrity testing and monitoring of nuclear power plant primary circuit components

Frequently Asked Questions

What is the maximum continuous operating temperature for the GH150 sensor?

The GH150 is rated for continuous operation in environments ranging from -45°C to +600°C. Its construction using stainless Invar steel and a ceramic face ensures minimal thermal expansion and maintains sensor integrity and calibration stability across this extreme temperature range.

Does this AE sensor have a built-in preamplifier, and what is required to connect it to a data acquisition system?

No, the GH150 does not include a built-in preamplifier. It features a standard BNC connector output. For operation, you must connect it to a compatible external preamplifier (such as a PAS or PAV series unit) which conditions the high-impedance AE signal before input to your data acquisition system or analyzer.

How is the GH150 sensor mounted in the field?

The sensor features a built-in magnetic base at its mounting end, allowing for quick and secure attachment to ferromagnetic surfaces like steel pipelines or vessel walls. For non-magnetic surfaces or more permanent installations, mechanical hold-down clamps (included) can be used to secure the sensor body.
