Leak detection hydrophone sensor HP-3010A

monitoringcommunicationfor pipes

Product Overview The HP-3010A hydrophone sensor is a miniature hydrophone manufactured using a semiconductor-based MEMS technology platform. It is designed for underwater acoustic signal detection where small size, light weight, and consistent response are required. The sensor features a wide 5kHz–100kHz bandwidth, high sensitivity, and a built-in preamplifier with 40dB gain. Thanks to its compact footprint, HP-3010A can support deployments where space is limited and where multiple hydrophones may be needed to form an array.
