Route search complex "Stalker" 80-14 (Li-Ion)

The route finder "Stalker 80-14" (Li-Ion) 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 80-14 locator includes a GT-80 generator and a PT-14 receiver (Li-Ion)

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 80-14 locator:

• “Compass” function - schematic display of communications on the receiver display;
• tracking and coordinating location in a worldwide coordinate system;
• communication with a computer via Bluetooth, memory for 10,000 measurements;
• High-precision positioning (up to 1 cm) together with GPS RTK – PrinCe LT700H tablet;
• the ability to use a smartphone instead of an external GPS/GLONASS module;
• for gas services, ECP frequencies are separately allocated for operation without a generator;
• the Stalker 80-14 locator will automatically display the depth and current strength (even in passive modes);
• remote control of the generator via the GSM network;
• frequency 33 kHz for contactless supply of the generator signal to communication;
• 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 Stalker defect detection systems: 80-24, 80-14, 80-12;
• PT-14 receiver menu in Russian and English.

Receiver Stalker PT-14 (Li-Ion)

Display function compass

• lightweight design (weight 1.7 kg)
• bright color display
• Extended operating time up to 14 hours from Li-Ion batteries

 Continuous display of all necessary parameters:

• “Compass” function indicating the direction of the current (from the generator/to the generator) to prevent accidental switching to “foreign” communication;
• Scales of “maximum” and “minimum”;
• Depths and strength of communication current at all active frequencies;
• Scale “probe” - to determine the location of damage;
• 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.

Recording in the memory of the PT-14 receiver:

• level of signals from magnetic antennas and the “ZOND” 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 “PROBE” 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.
