FLASHPHONE Digital Acoustic/Ballistic Cable Detector

FlashPhone Digital Acoustic/ballistic detector is designed to pinpoint the exact location of primary fault location when combined with a capacitor impulse discharge unit (thumper). During the flashover at the fault both a magnetic and acoustic signal is generated. There is a time delay between these two signals and the FlashPhone displays this signal as a number.

The closer you get to the fault will show a decrease in the number that is displayed. The magnetic signal bar graph shows intensity (magnitude) of the magnetic field generated by the thumper into the cable fault. It also can be used to locate the correct cable route when the maximum bar deflection is indicated. The microphone is designed to be used with an earth probe for soft ground conditions and the flat ground contact can be used on concrete or asphalt.

The FlashPhone unique combination design of seismic and electronic sensor technology, plus microcomputer technology and digital signal processing is the key to its superior performance and high sensitivity. It is well suited for use with impulse discharge  units with low Joule energy capabilities.
