Fisher SONDE-8K 8.2 kHz Pipe Sonde Signal Transmitter

Fisher SONDE-8K 8.2 kHz Pipe Sonde Transmitter for Underground Pipe Tracing

The Fisher SONDE-8K is a compact pipe sonde signal transmitter designed for locating and tracing non-metallic pipes and ducts. Operating at 8.2 kHz, this transmitter is inserted directly into the pipe using a push rod and detected from above ground with compatible Fisher receivers such as the TW82 and TW8800 line tracers.

8.2 kHz Signal Transmission for Accurate Pipe Location

• Self-contained 8.2 kHz signal transmitter for pipe tracing
• Designed for insertion into non-metallic pipes and ducts
• Works with Fisher TW82 and TW8800 line tracer receivers
• Provides detectable signal peaks along the transmitter body
• Supports underground pipe path tracing and blockage detection

Compact Sonde Design for Pipe Inspection Systems

The SONDE-8K is engineered for use inside sewer and utility piping where traditional locating methods cannot detect non-metallic materials. Once inserted with a push rod, the transmitter emits a locating signal that allows technicians to identify pipe direction, depth, and potential obstructions using a compatible receiver.

Typical Utility and Pipe Tracing Applications

• Tracing underground sewer and drainage pipes
• Locating blockages such as root intrusions in pipelines
• Utility locating for non-metallic pipe systems
