Strainsense Enterprises, IncFounded in 1973 by former U.S. Steel Research project engineer Ronald S. Vranka, Strainsense Enterprises designs and manufactures custom load cells and force-measurement systems for research, testing, and industrial applications. The McKeesport company pioneered digital load-cell calibration systems and still builds its products in the USA, while also providing ASTM calibration and repair services for equipment from any manufacturer. Son Layne Vranka became president in 1992, and many employees have remained with the company for more than 25 years.MCKEESPORT, PA
Spectron SensorsSince its founding in 1947 as Spectron Glass Laboratories, Spectron Sensors has built its identity around American-made sensor engineering in Long Island, New York. The company first produced neon signs before shifting to electrolytic tilt-sensor work for Sperry Gyroscope in 1948, then developing proprietary technology for demanding aerospace, military, and industrial applications. Its staff works directly with customers’ engineers on custom sensing solutions, including equipment designed for extreme environments.HAUPPAUGE, NY
TensitronTensitron has been an American instrument maker since 1935, when physicist Dr. Erwin J. Saxl founded the company’s predecessor to solve industrial tension-control problems. Now part of family-owned KTC Instruments, the Pittsburgh operation preserves that engineering heritage by making precision tension meters for manufacturers and maintenance teams worldwide. Its in-house ISO/IEC 17025:2017-accredited laboratory also calibrates the instruments it builds to NIST-traceable standards.PITTSBURGH, PA
Stein Seal CompanySince 1955, Stein Seal Company has designed and manufactured custom seals and precision components for demanding aerospace, nuclear, marine and industrial equipment. The privately owned company has grown from five employees in rented space to more than 200 employees and over 100,000 square feet at its specialized manufacturing facility, with engineering, repair and dynamic testing capabilities under one roof. Its Pennsylvania operation holds ISO 9001:2015 and AS9100D certifications, along with NADCAP approvals and FAA and EASA repair-station certifications.336412KULPSVILLE, PA
