CL1400 Pipeline and Cable Locator consists of a Transmitter, a Receiver and Accessories, used in the underground pipeline & cable route accurate locating, the burial depth measuring, long distance tracing, and insulation fault point detecting. We adopted multicoil electromagnetism technology in CL1400 Pipeline and Cable Locator, enhanced the precision of the pipeline and cable location and the burial depth, and the goal pipeline identification capability. It could accurately carry on tracing and location to the goal pipeline and cable in the crowded pipelines and cables.
CL1400 Pipeline and Cable Locator is widely used in the telecommunication, mobile, electric power, water supply, natural gas, physical prospecting, petrochemical and city construction, etc.

1. Detect the route of underground pipeline and cable
2. Measure the burial depth of underground pipeline and cable
3. Detect and locate the insulation fault point of the underground pipeline and cable
4. Identify the goal pipeline and cable under multiple underground pipelines and cables situation

1. Adopt the advanced signal processing technology and the latest integrated circuit to achieve outstanding test performance.
2. The detecting signal transmission method includes:
(1) Injection method: with injected the spot on the pipeline to detect the route and the burial depth, this method measuring accuracy is high, and good anti-jamming ability.
(2) Clamping method: used in a pipeline with the exposed section and easy to clamp.
(3) Induction method: used in a pipeline without injection point or without exposed section.
3. Many kinds of detecting frequency: 480Hz, 7.7KHz , 31KHz and 61KHz, which are four kinds of active frequency and 50Hz of passive frequency using in electric cable; The user may carry on the choice according to the different environment (need special detecting frequency please indicate specially in order contract).
4. Enhancement test efficiency by different localization pattern and function:
(1) peak value pattern: Determines the position through the maximum route signal.
(2) valley value pattern: Determines the position through the minimum route signal
(3) route direction detection: Direct-viewing, instructs the route rapidly the direction.
(4) insulation fault finding (FF): Detect and locate the insulate fault point of pipeline and cable .
(5) Stethoscope: find loading signal on the pipeline through stethoscope from the multitudinous pipelines.
5. Auxiliary functions:
(1)  Automatic control receive gain: The automatic control receiver gain can keep the receiver to be at the optimized status and avoid manual operation.
(2) Sound function: The receiver reflects the detecting signal intuitively through the tonality changing.
(3) Check the detecting condition: When the transmitter in injection mode, first test the insulation resistance and the residual voltage of pipeline, then load the signal to a pipeline. When the value of the insulation resistance too small (almost in short-circuits) the transmitter will withdraw automatic from this mode, when the residual voltage is so large the transmitter will warn, the operator must stop to load signal and shut off the transmitter.
(4) Battery value testing: Real-time detection of battery, when the voltage lower than the protect value, the transmitter will warn and automatic shut-down.
(5) Power save: The machine will be off to save the power if the transmitter is not be operated after booting in 30 second, and if the receiver is not be operated after booting and no other keystrokes about 10 minutes.

The certificate shows that a component/subsystem can be used in a specific application according to a requirement class (RC) or a integrity level (SIL). The system integrator and end user must always be aware of how to use certified components/subsystems in safety-related function, respectively a safety instrumented system. Because of the many different possibilities and how to configure a safety system, the end user must get the related information from the manufacturer of the certified component/subsystem.



The CE marking is a mandatory European marking for certain product groups to indicate conformity with the essential health and safety requirements set out in European. To permit the use of a CE mark on a product, proof that the item meets the relevant requirements must be documented.
