Electronic Film-Tension Sensor for Analyzing Film-Transport Problems

Richard Dull

One of the most accurate electromechanical position-sensing instruments available is a compact tension transducer in which the vagaries of film-handling equipment are revealed for meticulous scrutiny. As a result of the well-planned mechanical construction of this transducer, its casual use is surprisingly free of the errors in angular relationships and random friction excesses generally associated with informal testing. This makes it an invaluable adjunctive aid to the development engineer, who normally cannot afford the time and cost involved in special fixturing for transistory or small-run physical testing. Nominal tensions can be instantly meter read, while transient disturbances of significant bandwidth (with respect to film-transport systems) are readily tabulated with the aid of slight additional instrumentation.
