| Model | LD9500 Full-Frequency Cable & Pipe Locator | |
| Main Functions | Detects the accurate location, depth, direction, route, and signal current strength of underground cables and metallic pipelines from the ground surface. | |
| Key Features | Full-frequency receiver, real-time depth measurement, compass guidance, 10W high-power transmitter, and color display for deeper, farther, and more accurate utility locating. | |
| Applications | Widely used by municipal planning, design, and construction organizations for locating water supply, drainage, gas, heating, industrial pipelines, as well as power and telecommunication cables. | |
| Working Principle | Uses electromagnetic locating technology. The transmitter applies a signal to generate a secondary electromagnetic field around the utility, and the receiver detects this field from the surface to determine utility information. | |
| 2. LD9500 Full-Frequency Receiver | ||
| Item / Function | Description | Remarks |
| Full-Frequency Receiving Capability | Preset with 55 major locating frequencies, allowing flexible selection according to field conditions and significantly improving performance in complex utility environments. | |
| Highly compatible and can work with transmitters from various brands. Existing locator users can upgrade system performance by purchasing only the receiver. | ||
| Advanced Receiving Technology | High-sensitivity receiving coils with a dynamic range of up to 140 dB enable detection of deeper utilities and longer locating distances. | |
| Special coil receiving technology narrows signal response range, improving signal resolution and locating accuracy in congested utility areas. | ||
| Dual-coil technology eliminates or suppresses electromagnetic interference from nearby above-ground and underground utilities. | ||
| Anti-clutter filters automatically removes interference signals, greatly improving signal-to-noise ratio and stability for accurate locating in congested areas. | ||
| Dual-core high-speed processor improves signal processing speed, enabling faster utility locating, depth measurement, and current measurement. | ||
| Provides peak signal indication, null response distance arrows, and limited signal response indication, clearly showing utility presence and reducing false detection. | Intuitive Color Display | |
| Color Display & User Interface | The color display provides clear visibility in both bright sunlight and low-light conditions. | |
| Real-time depth measurement provides reference depth information; compass guidance indicates utility direction for accurate locating. | ||
| Software Upgrade | Instrument functions can be configured and upgraded through software, with future support for new frequencies, interfaces, data storage/download, GPS, and other features. | No hardware modification required |
| locating method | Peak mode provides strong interference resistance and higher locating and depth accuracy in congested utility environments. | Suitable for dense and complex utility conditions (recommended mode). |
| Null mode offers high signal sensitivity with moderate interference resistance, suitable for deep utilities and longer locating distances. | Suitable for single utilities with large burial depth or long locating distance. | |
| Wide peak mode provides interference resistance and sensitivity between peak mode and null mode. | Used for locating single utilities at greater depths. | |
| depth measurement method | 70% characteristic point method, a depth measurement method proven through years of field application. | Maintains depth accuracy even under complex conditions. |
| Direct-read depth measurement provides quick and straightforward depth readings. | Suitable for depth measurement and reference depth checking on single utilities. | |
| 3. LD9500 High-Power Transmitter | ||
| Item / Function | Description | Remarks |
| 10W High-Power Output | Uses 10W high-power output with maximum voltage of 50V and current of 1A, providing excellent direct-connection transmission performance. | |
| High-Efficiency Induction Coil | Increases induction coil magnetic moment, improving induction performance by approximately 30% compared with other 10W transmitters. | |
| Highly Adaptable Output | Direct connection and induction output performance exceed similar products, especially suitable for deep and long-distance utility locating. | |
| Automatic Impedance Matching | Maximizes high-power performance and enables effective signal induction in high-resistance utilities or dry soil conditions without strict grounding requirements. | |
| 4. Signal Application Methods: Maximize Current on the Target Utility While Suppressing Interference from Other Utilities | ||
| Item / Function | Description | Remarks |
| Direct Connection Method | Provides high signal-to-noise ratio and excellent signal selectivity. | Suitable for utilities with access points and dense unconnected utility networks. |
| Clamp Method | Provides good selectivity and current gathering effect on utilities. | Used for locating dense cables and small-diameter pipes. |
| Induction Method | Simple, fast, and effective. | Suitable for utilities without access points or known connection points, where direct connection is not practical. |
