Tensitron History

Tensitron, formerly known as Saxl Instrument Company, was established in 1935 by Dr. Erwin J. Saxl, a well-known physicist. He designed instrumentation for the developing mechanized textile industries that could precisely measure tension, thereby providing a way to ensure product quality and consistency. Dr. Saxl was the inventor of, and held numerous patents on, the first tension meters.

As technology advanced, so did Tensitron's instruments. By the late 1940s and into the 1950s Tensitron had already designed and offered specific instrumentation to such diverse industries as: Wire, Filament, Paper Converting, Coil Winding, Aviation, and both Government and Civilian research facilities worldwide. Subsequent years saw the introduction of instrumentation for Fiber Optics, EDM Manufacturing, Aerospace, and other technologically demanding industries. Today, whether you're working in high temperature, high torr environments or simply needing to meet stringent ISO and QS requirements, Tensitron is here to help.
