Superior Signal Company is a U.S.-based manufacturer that specializes in smoke-generating devices and ultrasonic instruments. Its history traces back to the early 1950s when it designed military and ship distress signals for government agencies, and in 1954 it developed a civilian-safe smoke with no explosive materials. Based in Old Bridge, New Jersey, about 35 miles south of New York City, the company produces equipment used to observe air flow and to test smoke-control and exhaust systems across a range of industrial and building applications. In 1991 it broadened its product line with the AccuTrak line of ultrasonic leak detectors, designed for plant maintenance tasks such as locating leaks, assessing bearing wear, and monitoring HVAC systems. The business emphasizes service and support alongside domestic manufacturing, and it remains a family-owned operation producing most of its equipment in the United States.
