8880-DFF定向接收机

The 8880-DFF cable, pipe, and directional fault finder offers utility locators three active frequencies -- 815 Hz, 8 kHz, and 82 kHz -- ensuring adequate signal is applied to buried utilities in any environment. Multiple active frequencies allow the user to accurately locate with a minimum of "ghosting" to adjacent lines while maintaining the ability continue locating past faults and around conduit bends. Passive frequencies identify "live" and charged lines by their naturally occurring electromagnetic fields. The 8880-DFF offers one passive frequency - 50/60 cycles - allowing line locating without the use of a transmitter.

 

Updated transmitter functions include improved transmitter induction, dual frequency coupled induction at 8 kHz and 82 kHz, and automatic impedance matching for direct connections. The 2.6 watt transmitter has the ability to simultaneously apply an 815 Hz and 82 kHz frequency to a utility. From one transmitter setting the user can locate the main line as well as other services by "lighting up" the entire site. This set-and-forget feature saves you time and money by reducing the need to repeatedly relocate the transmitter. All functions are accessed via weather-proof membrane buttons and both user input and transmitter status are verified with audible responses.

 

The ergonomically designed and balanced 8880-DFF receiver provides instant push-button depth up to 15 feet and current measurement to identify the target utility in crowded easements. Proximity cues to the tracing signal are given to the user through either peak or null tone modes while the backlit digital display provides both relative and actual signal strength.

 

Line faults can be quickly and simply located when used with the included "A-frame" ground return probe. The receiver's backlit digital display provides instant directional feedback and guides the user forward and back along the line to the precise location of the fault.

 

Conduit pinches can be located using the optional Sonde accessory. Operating on active frequencies of 815 Hz or 8 kHz, Rycom Instruments® Sondes are pushed into non-pressurized conduits and pipes until they reach the point of pinch or blockage. Traceable 20 feet in the air and 10 feet in cast iron, the 8880-DFF receiver will identify the precise location of the line blockage.
