A RESONANCE MEASURING WIRE TENSION MONITOR FOR HIGH-ENERGY PHYSICS

The design, construction, and operation of a wire tension monitor is p resented. The technique used is unique in that the electric force is u sed to excite the wire into harmonic resonance. The amplitude of the m ire is in turn monitored using the variation of the oscillating wire's capacitance measured by a resonance circuit. Finally, the resonance i s found electronically using phase lock loop techniques. Wire tension is measured to an accuracy of 0.3% with this device.
