Description

SONEL TDR-420 TIME DOMAIN REFLECTOMETER

TDR-420 time-domain reflectometer is designed to detect where faults in metal wires are. This time domain reflectometer is designed for electrical wholesalers and cable dealers, electrical installation companies, maintenance personnel at manufacturing plants and building personnel.

This time domain reflectometer meets the expectations of all those who have to accurately locate a fault and wire end in either power or telecommunications cables.

SONEL reflectometers are distinguished for their long operating range of up to 6,000 m (TDR-420), very low margin of error in measurement (in the order of 1%) and the ability to adjust both the velocity of propagation and the impedance of the cable which is under investigation. By using two cursors there should be no problem with determining both the distance to two faults and the distance between them.

The TDR-420 time domain reflectometer is equipped with a readable colour display that, due to its 320 x 240 pixel resolution, allows the fault location to be indicated even more accurately.

In the TDR-420 time domain reflectometer, a handy help function has been added to facilitate the interpretation of the result obtained during measurement. Thanks to this function, a user can quickly determine the type of anomaly that is present in the cable segment which is being examined, by comparing the displayed reflectogram with typical fault shapes.

In response to the customers needs the new TDR series model has been designed to operate in difficult environmental conditions. A unique casing with the IP67 ingress protection rating ensures that the time domain reflectometer is both waterproof and dustproof.

An additional advantage is the elastomer coating of the casing that prevents the time domain reflectometer from slipping out of the hands and provides protection if it should be accidently dropped.
