Leak detection acoustic emission sensor W500/3

monitoringfor composite and concrete structure inspectionfor metal structure inspection

Description
The W500/3 is a miniature acoustic emission sensor designed for medium- and high-temperature monitoring. It has a resonant frequency of 260 kHz and a broadband response from 40 kHz to 600 kHz, making it suitable for detecting and monitoring crack growth and structural damage in pressure vessels, storage tanks, pipelines, composite materials and metal structures. The sensor features a stainless-steel case, ceramic face, and an integral BNC cable with side connector.

Applications
