ASG History (cont.)
Alliance Sensors Group is a recently formed company that traces its lineage back 70 years to the
founding of Schaevitz Engineering by Herman Schaevitz in 1942. He built Schaevitz Engineering
into the premier name in LVDT position sensing technology before retiring in 1976 and handing
over the company to his son Howard. As chairman and CEO, Howard A. Schaevitz guided
Schaevitz Engineering for more than a decade, building it into one of the world's largest
manufacturers of position sensors for the industrial and aerospace markets.
In 1986, Schaevitz Engineering was sold and in 1989, Howard Schaevitz departed the firm. In
1994, Howard Schaevitz and several former Schaevitz employees founded Macro Sensors, the
second generation of Schaevitz sensor businesses, to make improved LVDT-based products. In
2005, Macro Sensors was sold and eventually both Howard Schaevitz, CEO, and his son Harold
Schaevitz, a sales engineer, left Macro Sensors.
In 2012, Howard A. Schaevitz and Harold G. Schaevitz formed Alliance Sensors Group as a division
of H.G. Schaevitz LLC, the third generation of Schaevitz sensor companies, with Harold Schaevitz
as CEO. One of the first actions of the new company was to acquire from Everight Sensors
Corporation the heavy duty LVDTs and support electronics products designed specifically for the
electric power generation industry.
