Route search complex "Stalker" 80-24 (built-in GPS/GLONASS module, Li-Ion)

The Stalker 80-24 route finder is designed to determine the planned position and depth of communications, places of damage to the insulation of pipelines and cables with further cartographic analysis.

The delivery package for the Stalker 80-24 locator includes a GT-80 generator and a PT-24 receiver with a built-in GPS/GLONASS module

The principles of operation of the Stalker series locators with high-precision GPS RTK tablet PrinCe LT700H can be found in the training film https://youtu.be/ixbdZwx_-n8

General features of the Stalker 80-24 locator (built-in GPS/GLONASS module, Li-Ion)

• The “Compass” function is a schematic display of two communications on the receiver display;
• Finding the position of transmitting probes and television inspection cameras;
• Trace and coordinate location in a worldwide coordinate system;
• Built-in GPS/GLONASS module;
• High-precision positioning (up to 1 cm) together with GPS RTK – PrinCe LT700H tablet;
• Possibility of using a smartphone instead of an external GPS/GLONASS module;
• Communication with a computer via Bluetooth, memory for 10,000 measurements;
• Remote control of the generator via GSM network;
• Frequency 33 kHz for contactless transmission of the generator signal into communication;
• for gas services, ECP frequencies are separately allocated for operation without a generator;
• the Stalker 80-24 locator will automatically display the depth and current strength (even in passive modes);
• search for communications at a depth of up to 10 m and a distance of up to 10 km from the generator connection point;
• the presence of five operating frequencies and adjustable output power of the GT-80 generator (from 10 to 80 W). This generator is included in the set of defect detection complexes Stalker: 80-14, 80-12;
• The PT-24 receiver menu is in Russian, English and Chinese.

Receiver Stalker PT-24 (built-in GPS/GLONASS module, Li-Ion)

• lightweight design (weight 1.9 kg)
• built-in GPS/GLONASS module
• Larger, brighter color display
• Extended operating time up to 20 hours from Li-Ion batteries

Continuous display of all necessary parameters:

• “Compass” function with simultaneous schematic display of two communications:

- the first with current flowing from the generator; - the second with flowing industrial frequency current (cables) or ECP (pipes);

• Scales of “maximum” and “minimum”;
• Depths and strength of communication current at all active frequencies;
• Signal polarity - at the point of insulation damage, the sign “+” changes to “-”;
• Function of current direction (from the generator/to the generator), to prevent accidental switching to “foreign” communication;
• Sharp maximum mode.

In the "PROBE" mode, it searches for the position of transmitting probes and television inspection cameras that have an autonomous transmitter during in-line inspection at frequencies of 512 or 32768 Hz (33 kHz)

Recording in the memory of the PT-24 receiver:

• level of signals from magnetic antennas and the “SENSOR” input;
• directions to communication;
• indications of the depth of the communication and the magnitude of the current in it;
• direction of search current;
• relative polarity of the potential difference at the “SENSOR” input;
• phases of the signal at the “ROAD” input;
• operating frequencies;
• local date and time at the time the readings were taken using GPS information;
• coordinates of the location where readings were taken using GPS information.
