APPOINTMENT

The digital display of damages selector of the Universal-911 M-6 type intended for:

• detection of a lining route of power cables;
• detection of a lining route of current-carrying pipelines (gas pipelines, oil pipelines, wires of ammonia, water pipes, pipelines of sewer and thermal networks);
• detection of a lining route of the pipelines executed from nonmetal (at presence in them a current-carrying liquid);
• detection of a lining route and depth of arrangement contours and grounding tyres;
• definition of the depth of arrangement of cables and pipelines;
• detection of places of damages of power cables, (breakage, short circuit, places of fall of isolation) by an induction method and on the active electric aerial;
• detection of places of defects of isolation in underground or underwater pipelines;
• detection of places of unapproved inserts on pipelines;
• detection of places of leak in pipelines by an acoustic method of intensity of noise in a damage place;

The Design of the selector of damages provides:

• operation at telecommunications agencies and electric networks;
• operation at the enterprises where pipelines are used;
• operation at the enterprises specializing on inspection and repair of cables and pipelines;
• work of the receiver and generator on three frequencies – 477Hz, 1177Hz and 8475Hz;
• the big target current of the generator on loading 0,1 Ohm – to 80А;
• work of the receiver together with the generator by an induction method on the magnetic aerial;
• work of the receiver together with the generator with the active electric aerial;
• work of the receiver without the generator in a wide strip of frequencies;
• work of the selector in a mode of the acoustic receiver;
• indication of an accepted signal by the pointer indicator;
• indication of an accepted signal on the liquid crystal indicator in a digital form in all dynamic range, from minimum to a maximum level of intensity of an electromagnetic field, at various modes of search or definition of places of damages;
• the control of an accepted signal on headphones;
• separate adjustments of the pointer sensitivity indicator and loudness of phones;
• the control of a condition of accumulators of the receiver and possibility of their additional charge;
• high sensitivity and noise immunity of the receiver for confident work in any difficult conditions of electromagnetic hindrances;
• high sensitivity to weak acoustic signals;
• digital indication of work of a geomicrophone at search of places of impulses of pipelines with liquids, air or gas;
• stability of electric parametres at various differences of temperatures;
• a power of generators from a network 220WATT 50 Hz;
• small weight, durability and reliability of constructive decisions, small overall dimensions;
• 15 years resource at daily work;
• a guarantee of non-failure operation 24 months.

SERVICE CONDITIONS

The selector of damages ensures functioning at:

• an ambient temperature from - 30 degrees C to +50 degrees C;
• relative humidity of air to 80 %;
• pressure of a power line 220±30/50WATT with frequency 50Hz;
• pressure of the receiver power 12±2/0,5 and 8,4±1WATT at a direct current;

The receiver is protected from wrong connection of sources of a direct current.

The generator is protected from overloads at the wrong coordination of an exit of the generator with resistance of loading.

The equipment is executed in carrying execution.
