MP-25 High-Sensitivity Hydrophone

PRODUCT DETAILS

The MP-25 is a transformer-coupled hydrophone. This vibration monitoring solution has eight piezoelectric crystals connected in an acceleration-canceling arrangement with each crystal operating in the high-sensitivity bender mode. The crystals and transformer are permanently molded in a durable polyurethane case. This sealed unit has a thermoplastic resin outer case with easy access ports for polarity testing. The Sidewinder version does not have the outer case.
