The Ultran GroupFounded in 1977 as Ultran Laboratories, The Ultran Group develops ultrasonic transducers, inspection systems, and application solutions for nondestructive testing and medical therapy. The State College company pioneered non-contact ultrasound in the late 1990s, creating a way to transmit ultrasound through air for inspecting uncured materials and production-line parts without physical contact. Its later piezoelectric composite and phased-array developments support applications ranging from composite and battery-cell inspection to emerging medical treatments.STATE COLLEGE, PA
Sensaras LLCFounded in 2013, Sensaras LLC designs and manufactures ultrasonic liquid-level sensor systems from Long Island, building on ultrasonic expertise that began in the region in the 1970s. The company develops customized sensors for demanding applications, including semiconductor chemical monitoring and military programs, and has earned multiple military contracts since 2014. Sensaras moved into a new facility in 2019 and powers its operation with solar panels that can also send electricity back to the grid.BOHEMIA, NY
NDT International, IncOperating under the same ownership and at the same location since January 1971, NDT International, Inc. designs and supplies nondestructive testing instruments and provides related technical services. The West Chester company began as a manufacturer’s representative and supplier of ultrasonic personnel, later developing patented monitoring equipment and instruments used by nuclear facilities and the U.S. Navy.
