The MP-24 is a transformer-coupled hydrophone. This vibration monitoring solution has four 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.
- Minimal sensitivity-change with depth
- Acceleration noise-canceling configuration
- Easy method to check polarity
