GL21-LVR8 Intelligent Gas PE Pipeline Locator

Product overview:

The product features are as follows:

Damage prevention and work efficiency are the biggest challenges faced by our customers

The brand-new GL21-LVR8 can solve these problems. This is our advanced intelligent acoustic locator for gas PE pipeline, and the demand of front-line operators for the instrument was fully considered in the design.

Both detection speed and detection accuracy are taken into account

GL21-LVR8 is a two-in-one receiver with two detection modes: listening mode and square column diagram, which is efficient and fast, and has the accuracy of square column diagram digital display mode.

Some features of transmitter GL21:

● Frequency and power can be adjusted. There are four modes of frequency output, including constant frequency, double frequency conversion, triple frequency conversion and pulse. According to the detection distance, the output power can be adjusted in multiple steps, and there is no blind spot detection in various situations of short distance, medium distance and long distance; The cooperation of multi-frequency, multi-mode and multi-power can not only ensure the accuracy but also ensure the detection distance, and also achieve better detection effect;

● The product is equipped with wireless remote control function, which can remotely control the start, stop, frequency and power of the transmitter within 3 kilometers, and the remote controller can also remotely monitor the status of the transmitter;

● The transmitter has a built-in ultra-large capacity battery, which has a long standby function for 12 hours continuously;

● The transmitter has higher output power and can transmit stronger signals. Can realize deeper and farther detection;

● Emit a specially modulated frequency, which greatly improves the signal recognition of the instrument in a noisy environment;

● The remote controller is on standby for a long time, and it will automatically turn off after 150 seconds without any operation.

Features of receiver LVR8:

● The receiver probe adopts high-sensitivity piezoelectric sensing technology, which has high sensitivity and can monitor weak sound signals;

● It has a five-level hearing protection function, which can prevent loud sound from entering the earphone and protect the user's hearing;

● Recording function: you can record live audio information, and people who are not on site can also participate in listening to help determine the pipeline positioning;

● In the detection mode, the size of the signal measured at each point is represented by a square column diagram, which is convenient for comparison and easier to locate the pipeline position;

● With sounding function, sounding and detection can be completed at one time, and the operation is simple and efficient. Adjustable according to environmental signals;

● Multi-function color touch smart screen, without any buttons, and the graphic display is clear and intuitive;

● Wired headphones and Bluetooth headphones can work at the same time, and one machine can be tested by two people at the same time, which improves the accuracy and efficiency of detection;

● The audio width can be adjusted freely, and the minimum bandwidth can reach 20Hz;

● The frequency of the collected vibration signal is displayed on the screen in real time, and you can also watch the numerical value to assist positioning when listening;

● The receiver can be matched with other similar gas PE pipeline locator transmitters in the market. The receiver has the function of accurate frequency measurement, which can measure the emission frequency of transmitters of other brands of pipeline acoustic locator and can be used in matching;

● The receiver, probe and box are small and exquisite and easy to carry. The triangular claw can be quickly installed without disassembly, and the hard ground mode and soft soil mode can be quickly switched;

● The strap design with adjustable length of the receiver is more convenient for on-site operation;

● By operating the knob on the receiver to rotate and press, the functions such as gain and volume adjustment, mute and measurement that are often used in detection at ordinary times can be realized.
