1. ATLAS Wire Tension Measurement system

2. ATLAS Wire Tension Measurement system
The system uses electrostatic force to excite mechanical oscillation around the wire fundamental harmonic resonance
The oscillation amplitude is sensed by measuring the capacitance variation in the wire-tube system
Changing the high voltage modulation frequency  mechanical resonance curve
Fully operated by a PC LabVIEW program
