Description

The GH150/1 is a specialized piezoelectric acoustic emission sensor designed for structural health monitoring in high-temperature industrial applications. Its core utilizes a high-stability ceramic sensing element housed within a stainless Invar steel body, providing excellent thermal stability and resistance to thermal expansion mismatch. The sensor’s wideband frequency response captures a broad spectrum of acoustic events, from low-frequency stress waves to high-frequency crack propagation signals.

Engineered for permanent installation or temporary testing, the sensor features a magnetic base for secure mounting on ferromagnetic surfaces and an IP68 sealing rating for protection against dust and prolonged water immersion. The integrated 3-meter shielded cable with a BNC connector ensures reliable signal transmission to compatible preamplifiers and data acquisition hardware, making it suitable for integration into industrial PLCs, dedicated AE systems, and predictive maintenance networks.

Key Features

High-temperature piezoelectric ceramic sensing element for stable operation up to 350°C.
Stainless Invar steel case and contact surface for superior thermal and corrosion resistance.
Broad frequency response range (60 kHz – 400 kHz) for comprehensive acoustic emission analysis.
IP68 protection grade ensures reliable performance in dusty, wet, and harsh industrial environments.
Integrated magnetic base (Hold-down H20) facilitates quick and secure installation on steel structures.
Side-exit BNC connector on a 3-meter integral cable simplifies field wiring and connection.
Optimized sensitivity (>73 dB) ensures high signal-to-noise ratio for early fault detection.

Frequently Asked Questions

What is the maximum continuous operating temperature for the GH150/1 sensor?

The QAWRUMS GH150/1 is rated for continuous operation in environments ranging from -20°C to +350°C. Its stainless Invar steel housing and ceramic sensing face are specifically engineered to maintain structural integrity and stable piezoelectric performance at these extreme temperatures, making it suitable for permanent installation on hot surfaces like boiler shells or process pipelines.

Does this sensor have a built-in preamplifier, and what type of connector does it use?

No, the GH150/1 does not have a built-in preamplifier. It is a passive piezoelectric sensor that outputs a raw high-impedance signal. It features an integrated 3-meter cable terminated with a standard BNC connector, which is designed for direct connection to an external preamplifier or compatible data acquisition system with a BNC input.

How is the sensor mounted, and is it suitable for outdoor or harsh environments?

The sensor includes a magnetic hold-down mount (H20) for quick attachment to ferromagnetic surfaces. For non-magnetic surfaces, adhesive or mechanical clamping can be used. With an IP68 protection rating, the sensor is fully sealed against dust and prolonged water immersion, making it robust enough for harsh outdoor and industrial environments, including those with high humidity, dust, or occasional washdowns.

What frequency range does this AE sensor cover, and what is its primary application?

The sensor has a resonant frequency of 150 kHz and a usable frequency response from 60 kHz to 400 kHz. This wideband range allows it to detect various acoustic emission events, from low-frequency stress waves to high-frequency crack growth. Its primary application is structural health monitoring and early fault detection in high-temperature industrial assets such as pressure vessels, power plant equipment, and pipelines.
