Pipe detectors and sensors

Pipe detector is a special device used for locating underground communications, such as sewer and water pipes. It allows to detect communications depth, location and damage points with quite accurate. Pipe detector registers fields emitted by different objects and makes a chart of communications displacement based on that data. Sensors are used to collect full data

The set consists of:

Our company developed a set of devices to search communications and damage points

Pipe detector TR-01

Receiver TP-01

Depth sensor T-g

Depth sensor T-b

Depth sensor T-m

Case

Main search methods for cables and pipes

Pipe detector allows to chart main underground communications in real-time mode. Large display shows calculated location and direction of those communications. Omnidirectional antenna detects full signal field for increased rapidity and accuracy. Pipe detector uses battery as a power supply

Receiver, included in specified set, allows to measure depth of communication line and its location. Data is transmitted from depth sensor to receiver via cable. Receiver uses battery as a power supply

Sensor for small depths. It is used to search communications laid down within depth range from 0.5 m to 3 m

Sensor for medium depths. It is used to search communications laid down within depth range from 3 m to 7 m

Sensor for greater depths. It is used to search communications laid down within depth range from 7 m to 15 m

Protection case is used for sensors durability increasing

Search method depends of searching object features. Some methods are optimal for searching underground power lines, sewer and water pipes

Passive emitting from underground is detected by pipe detector. The situation is different for active signal. The device generates signal at desired section of pipe. Search is carried out taking in account response to the generated signal

Receiver, included in specified set, allows to measure depth of communication line. Protective coupling should be installed between sensor and cable to prevent damage when passing bend pipe. Sensing method of search involves placing depth sensor into the pipe. Cable is connected to the sensor from the rear side. The sensor sends data, that is used to calculate depth, to the receiver. This method works well for searching municipal and industrial sewer pipes laid at greater depths

Follow specified steps to make marks along the entire route. Once single section is done, proceed with the next one until all of the communications will be located within the area

Improvised net is outlined when searching underground communications.
Operator of the device holds it horizontally and follows pre-planned route

Principle of action is based on the feature of underground communications to emit signals. This feature is typical for many of underground objects:
- power lines
- communication lines
- fiber optic cables
- water pipes
- gas pipes
- sewer pipes

There are six known methods:
- passive search method
- passive induction method
- direct connection
- use of flexible rod
- use of inductive clamps
- sensing

Data capture is carried out following the algorithm:
- move the device from left to right to detect signal
- lower the device to the surface while holding it horizontally, and determine the point with maximum signal strength
- make a mark on the surface at that point

Depth sensors have disposable temperature marks in their top part. Mark becomes black once the surrounding temperature overcomes 220 °F (104 °C)
