Cable Path Search Signal Transmitter

 

I. Main Features

Due to adopt the intermittent 15 KHZ sine signal amplitude modulation, in detecting the path of the buried cable and buried depth, which can effectively restrain power frequency interference and the same frequency interference of TV line frequency, improve the efficiency of the field detection.

Because of the amplitude modulation technology, this transmitter is not only suitable for the traditional differential beat receiver but also for the direct amplifier double voltage detection path receiver.The signal output power of this equipment is large, which can make the detected path distance reach more than 10km, which fully satisfies the buried path search work of all kinds of overlength laying cables of most enterprises.

 

II.Technical Data

1. Output power：When the load resistance for 10 Ω, output power greater than 30 w, and continuously adjustable.

2. Working frequency：15kHz

3. Working mode: intermittent (repeat cycle: 1Hz/ s), constant amplitude, amplitude modulation (modulation frequency: 400-1000hz) and Equiamplitude output are suitable for beating receiver, and amplitude modulation output is suitable for direct amplifier double voltage detection receiver

4. With automatic overheat and overload protection function, it can work for more than 8 hours continuously.

5. Working powder：AC 220V ±10%,50Hz.

6. Environment：temperature -20～50℃，The humidity is less than 95%.

 

 

Acoustic Magnetic Digital Display Synchronous Located
