Active Optical Cable Detector

Features

Purpose and scope of use

1. Detect the direction and depth of underground optical (electric) cables. The optical (electric) cable core wire is used to play sound, and the effective detection distance of the optical (electric) cable buried within 1.5 meters is greater than 25 kilometers. The effective detection distance of the optical (electric) cable buried within 2.5 meters is greater than 10 kilometers, and the plane position error is not greater than 5 cm.

2. Detect the direction and depth of underground metal pipelines (oil pipes, steam pipes, water pipes), and emit sound from metal pipelines (cable lead sheet sound), and the effective detection distance is greater than 1000 meters. Effective detection depth: within 200 meters, the effective detection depth is 3 meters; within 600 meters, the effective detection depth is 2.5 meters. (Without strong magnetic interference)

3. If equipped with a measuring probe (grounding gauge), it can measure the accurate position of the underground plastic optical (electric) cable insulation (ground gas) point. You can find bad obstacles with leakage resistance below 0.5 megohm within 15 kilometers.

Features of this machine

receiver

1. The receiver of this machine is designed in the shape of a retractable crutch, 2.4-inch LCD intelligent graphic display and audio signal output, battery power display, gain 30 gears adjustable, volume 5 gears adjustable, and the weight of the whole machine (including battery) is only 800 Gram, it has the outstanding advantages of small size, light weight and convenient carrying. The receiver adopts a telescopic rod to adjust the comfort level according to the height of the operation.

2. This receiver selects new low-noise, low-temperature drift integrated circuits and high-precision components, and carries out appropriate temperature compensation. It has the remarkable characteristics of narrow passband, small offset, high sensitivity and low noise.

3. The working frequency of this machine is 512Hz, and the receiving and transmitting parts of other types of detectors with the same working frequency can be used interchangeably.

launcher

1. The shape of this transmitter is portable and small in size and easy to carry.

2. Using foreign micro-power consumption computer components, low power consumption design, high work efficiency. The transmitter has a built-in 14.8v, 3800mAh large-capacity lithium battery, and the battery core adopts LG quality assurance to continuously stand by for 15 hours.

3. There is a power supply undervoltage protection circuit and impedance matching prompt function in the transmitter of this machine. When the grounding state is bad, the three output impedance lights will flash at the same time. When the contact is good, the corresponding light of the selected impedance flashes. In addition, since the design of this machine fully takes into account the various complex working environments on site and the testing requirements and working habits of testers of different levels, this machine has the following features and functions:

1. In order to adapt to various harsh working conditions on site, this machine adopts solid and fully sealed structure, commonly used switches adopt light-touch switches, and the emitter adopts anti-output short-circuit measures to avoid various possible damages to the greatest extent.

2. The probe of this machine adopts a gravity fully symmetrical balance structure, and considers the influence of the earth on the buried depth positioning measurement angle, which improves the measurement accuracy of the optical (electric) cable direction and the buried depth.
