APPOINTMENT

The digital display of damage selector of the Universal-911M type is intended for:

• detection of a lining route of power cables, cables of communication, heating cable for heat-insulated floors;
• detection of a lining route of current-carrying pipelines (gas pipelines, oil pipelines, ammonia wires, 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 of the contours and grounding tyres;
• depth definitions of arrangement cables and pipelines;
• detection of places of damages of power cables, communication cables, heating a cable (breakage, short circuit, places of fall of isolation) induction, a method of potentials and on the active electric aerial;
• detection of a line of a lining and places of damage of the latent conducting;
• detection of places of defects of isolation on underground or underwater pipelines;
• detection of places of unapproved inserts on pipelines;
• detection of places of leak in pipelines by acoustic method on intensity of noise in a damage place;
• search layer lost under a snow, the earth’s, leaves, covers of hatches, wells and other metal subjects.

The design of the selector of damages provides:

• operation of 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;
• operation at the enterprises specializing on installation and operation of a heating cable for heat-insulated floors;
• work of the receiver together with the generator induction, a method of potentials way;
• work of the receiver together with the generator on 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 ;
• work of the selector in a metal detector mode;
• indication of the received information on the pointer indicator;
• a linear exit for connection mill voltmeter with figure indication;
• connection of a multimeter of M 830 to a linear exit of the receiver for display to the liquid crystal indicator in a signal 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 damages places;
• the control of an accepted signal on headphones;
• separate adjustments of sensitivity of the pointer indicator and loudness of phones;
• simultaneously installation on a bar of the selector of the magnetic aerial and any of gauges (for specification of a line and search of damages to cables or pipelines);
• the control of a condition of accumulators of the receiver and possibility of their additional charge;
• high sensitivity and noise immunity of the receiver at optimum capacity of the generator for confident work in any difficult conditions of electromagnetic hindrances;
• high sensitivity to weak acoustic signals;
• stability of electric parameters at various differences of temperatures;
• a food of the generator from a network 220WATT 50 Hz or the external accumulator 24WATT;
• accumulator additional charge 24WATT from the generator;
• small weight, durability and reliability of constructive decisions, small overall dimensions;
• a guarantee of non-failure operation 24 months.

SERVICE CONDITIONS

The selector of damages ensures functioning at:

• an ambient temperature from - 40 degrees C to +50 degrees C;
• relative humidity of air to 80 %;
• pressure of a power line 220±30/50WATT with frequency 50Hz (for the generator at work from a network 220В 50Hz);
• pressure of a power of the receiver 9,6±2WATT a direct current;
• pressure of a power of the generator of voice-frequency impulses 24±2/12WATT a direct current. The receiver and the generator of voice-frequency impulses are protected from wrong connection of sources of a direct current.
