HT Instruments HT-5000 Intellingent Cable and Pipe Tracer System

Intelligent Cable and Pipe Tracer System

Professional system for finding grounding cables and pipes

Civil engineering work is accelerated, earth-moving machines are used efficiently and the risk of accidents is minimised thanks to the HT-5000 meter. This unit is especially designed to know the position and the depth of underground pipes and cables or cabling plans in a very quick and easy way. The model is composed by a Transmitter and a Receiver and the principle used is the propagation of a electromagnetic field inside a object crossed by a signal generated with a Direct coupling (finding energized or not energized objects with accessible parts) and Inductive coupling (signal spread by transmitter by integrated antenna) for finding of not accessible parts (e.g: earth-moving areas). The tracing can be performed also in Passive mode by the use of receiver only in order to locate cable or pipes crossed by 50/60Hz electrical current or radiofrequency signals. Both transmitter and receiver are designed with IP56 (protection by dust and water) for typical external “in field” environment and a wide number of optional accessories are available also for finding of non metal objects.

Direct coupling on cables and pipes. Direct galvanic coupling is practical for cables which are easily accessible and free of current. The method of connection is dependent upon the position and nature of the lines (e.g. insulation, cable conduit, accessibility of the cable ends)	Coupling by using special accessories The signal from the transmitter can be directly coupled into plug sockets, antenna connections and telephone jacks with the aid of a suitable adapter cable. In doing so, it is not necessary to disconnect the lines
Coupling via transmitter clamp In doing so, it is not necessary to disconnect the cables	Inductive signal coupling via integrated antenna of transmitter is highly recommended if unknown lines are to be located (e.g. at a construction site)
Surveying of an excavation work by using TX5000 and RX5000. make sure that a distance of at least 15 m is always maintained between the receiver and transmitter in order to prevent the coupling of the transmitter’s signal through the air	Signal coupling in non-metallic pipes by using of optional flexible probes
