8879-RF/CP电缆定位器

The 8879-RF/CP cable, pipe, and fault locator 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 8879-RF/CP offers two passive frequencies -- 50/60 Hz and your choice of RF (radio frequency) or CP (cathodic protection) -- 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 8879 receiver provides instant push-button depth up to 15 feet and current measurement to help identify target utilities 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.

 

The 8879-RF/CP can quickly and simply locate line when faults when used with the optional "A-frame" GRP (ground return probe). As the operator moves towards the fault the receiver will respond with rapidly peaking signal. When the "A-frame" is placed directly over the fault, the receiver will provide a null response.
