The TW9000 Multi-Frequency Underground Utility Locator is a high-performance tool designed for precise tracing of buried utilities. Equipped with advanced digital signal processing technology, it detects both active and passive magnetic fields, allowing operators to locate utilities with accuracy and efficiency. The TW9000 offers versatile connection methods, including direct connection, coupling clamp, and inductive modes, ensuring adaptability for various utility types and environments. Its selectable frequencies, ranging from 512 Hz to 82 kHz, allow for customized depth detection, and its rechargeable battery system ensures extended field operation with automatic power-saving features. The rugged design and compliance with IP64 and IP54 standards make it suitable for tough conditions, providing long-lasting reliability for professional use.
Modes:
- Peak & Null: Use this automated mode for most standard underground utility locating scenarios.
- Wide Peak: Use for lateral lines far from the connection point or for deeply buried utilities.
- Narrow Peak: Use for congested utilities.
- Null: Use for utilities with low field-shape distortion.
- Sonde: Use with sondes to trace conduit, pipe and drain locations and their blockages.
- Passive Power: Use for utilities that are energized by AC power currents. This mode does not operate with the Transmitter’s power source.
Frequencies:
- 512 Hz is recommended for long-distance tracing and deep utility detection, with minimal signal bleed-off.
- 8.125 kHz offers balanced tracing for moderate distances, suitable for general-purpose locating.
- 33.025 kHz is useful for tracing shorter distances, particularly in congested areas to avoid signal coupling into nearby objects.
- 82.175 kHz is ideal for short-distance tracing and helps in cases where utilities have insulated joints, improving conduction through capacitance.
