Article: SFT Vibrating Wire Weighing Technology
By K-Tron Process Group
In the mid-1970s K-Tron revolutionized bulk solids feeding with its introduction of the first truly digital load cell specially designed for process weighing applications. Based on an innovative vibrating wire concept, the new digital technology soon proved to be a significant advance over the analog LVDTs and strain gauges then in widespread use.
In the three decades since its introduction, vibrating wire weighing technology has established a strong reputation in the process marketplace for its high accuracy, long term stability, and operational reliability.
This paper traces the evolution of vibrating wire weighing technology driven by application and economic needs. Specific applications involving dynamic weighing and their associated challenges will be discussed, as well as a comparison to competing technologies.
