Vacuum Leak Test Systems
Vacuum leak testing is the principal leak test method for testing parts that could have leakage from an external source into their housings and casings. Parts like underwater sensors or housings, outdoor electrical housings, sealed components, and components associated with vacuum sources are all prime candidates for vacuum leak testing. Operation of instruments that supply vacuum to test parts instead of pressure works in a similar, yet essentially opposite, manner as pressure decay testing.

Hydrophones
Piezo is a critical element in producing a hydrophone for military and commercial underwater listening applications. Hydrophones utilize piezoelectric elements to detect sound pressure waves produced by underwater vessels, animals, and the environment. Hydrophones must have a flat frequency response that is proportional to the magnitude of the sound pressure wave. CTS piezo elements provide this critical function in hydrophones by providing excellent frequency response and high coupling factors necessary in hydrophone applications. CTS materials provide excellent electrical properties for hydrophone applications while allowing the ability to form the piezo element to the desired mechanical structure for the hydrophone.
