Advanced Signal Acquisition and Filtering Technology
Built on a proven design, and with Pathfinder SAF Technology™ at its core, the 8879v3 offers RYCOM’s most advanced signal acquisition and filtering technology. The 8879v3 cable & pipe locator offers a utility locator FrequencyFlex™ allowing users to adapt the system to their specific needs. Multiple active frequencies allow the user to accurately locate the cable and / or pipe with minimum interference and maintain the ability to continue locating past faults and around conduit bends. Passive frequencies identify “live” and charged lines by their naturally occurring electromagnetic fields. The 8879v3 offers multiple passive frequencies — 50Hz, 60Hz, Radio Frequency, Cathodic Protection Rectifier & CATV — allowing line locating without the use of a transmitter.
Updated transmitter functions include improved transmitter induction, multi-frequency coupled induction ranging from 8 kHz to 118 kHz, and automatic impedance matching for direct connections. The 5 watt or 10 watt transmitter has the ability to simultaneously apply an two frequencies 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 streamlines operation 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 8879v3 receiver provides instant push-button depth up to 7,6 meters 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 8879v3 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.
Conduit pinches can be located using the optional Sondes. Operating on active frequencies of 512Hz, 640Hz, 815 Hz, 8 kHz, or 33kHz Rycom Instruments® Sondes are pushed into non-pressurized conduits and pipes until they reach the point of pinch or blockage. Traceable 7,6 meters in the air and 3 meters in cast iron, the 8879v3 receiver will identify the precise location of the line blockage.
