Cable Locator and fault Pinpointer AR-027EM OWL general purpose:
- Pinpoint of cable faults by acoustic and electromagnetic methods
- Detection of cables (50/60 Hz mode) up to 6 m depth
- Survey the ground before the ground works (“Broadband” mode with frequency range between 0,05 and 2,0 kHz)
- Indirect measurement of the depth
- Detection the pipeline and utility lines intersection point (pipelines, power cables)
Overview
Cable locator Acoustic mode – fault Pinpoint (receiver АR-027 + acoustic sensor АS-227):
- Vsualization of acoustic sensor spectrum with the possibility of frequency choosing with minimum background noises;
- Storage of 30 signal level with a graph displayed;
- Graphic visualization (moving chart) of sequence measurements with the step of 1-2 seconds for determining max and min signal level and the place of it;
- Protection from random acoustic noise;
- Intuitive control system;
- Choice of bandwidth within the frequency range – in 8 levels of the limit “above” and “below”;
- Two-segment indication of frequency spectrum adopted (and “filtered”) signal;
Cable locator Electromagnetic mode (receiver АR-027 + electromagnetic sensor EMS-247):
- Detection distance up to 50 m;
- Filters 50(60), 100 (120), 512,1024,8192, 32768 Hz or “wide strip”;
- Operation with headphones;
- Operation without headphones (signal is transmitted to the built-in radiator);
Cable locator Step-Voltage mode for sheath fault pinpoint (receiver АR-027 + step-voltage sensor SVS-117):
Searching of cable faults at shorting of its armoring to the ground. Searching of outer insulation defects of metal pipelines (water, gas) at trenchless laying.
The receiver can be operated not less than 20 hours without recharging and replacing batteries (4x AA)!
The high sensitivity. The gain channel up to 100 dB!
