Partial discharge detection acoustic emission sensor GD40

for machine monitoringfor metal structure inspectionmeasurement

Description
GD40 is a passive piezoelectric acoustic emission sensor designed for use in noisy industrial environments. It provides a narrow-band resonant response at 35 kHz and includes a 1.7 m integral cable with a side-mounted double-core BNC connector. The SUS-304 stainless steel case and ceramic sensing face offer reliable coupling and environmental protection (IP68). The sensor suppresses common-mode noise to improve detection of high-frequency events.

Features

• Stainless steel case (SUS-304)
• Ceramic sensing face
• Integral 1.7 m cable with double-core BNC connector (side exit)
• Magnetic saddle hold-down mounting option

Applications
GD40 is suitable for detecting partial discharge in high-voltage equipment, acoustic emission from metal cracks and other high-frequency phenomena, especially in high-noise conditions. Typical uses include field inspections, condition monitoring and laboratory testing where a compact, waterproof sensor is required.
