Pipehorn Signal Clamp 5 inch

Heavy duty Signal Clamp for the Pipehorn 800-H and 800-HL Pipe and Cable Locator Series

Looking for a heavy-duty signal clamp to use with your Pipehorn 800-H or 800-HL pipe and cable locator?  This dual-frequency signal clamp allows conductive searches for buried underground pipelines, cables, and traceable fiberoptics when used with the Pipehorn 800 series pipe and cable locators.

Simply connect the clamp jack to your 800-H or 800-HL transmitter’s port and place the clamp on the exposed portion of the line you wish to locate. Direct connection gives the strongest signal to the locator in most cases. Will clamp onto lines up to 5 inches in diameter and can be used up to 13 feet from the transmitter.

The PA570 Pipehorn Signal clamp is designed for use when a direct connection is not possible, however a clamp can be placed around an accessible target conductor. The signal that the clamp and transmitter combination provide will be stronger and better isolated than simply using the transmitter to search through induction. In addition to being able to clamp onto conductor of 5 inches or less, the clamp has a threaded fitting on the handle to allow extension via a hot stick extension handle (not included).

PIPEHORN INDUCTIVE CLAMP SET-UP INSTRUCTIONS

1. Perform a quick system check of your Pipehorn 800 series pipe and cable locator by first plugging your clamp into the transmitter jack. When turned ON, the transmitter should emit a steady high pitch tone indicating a good battery and good signal output. Select low-frequency on your receiver (if using an 800-HL) and set the sensitivity knob precisely at 2. With the clamp laying on the ground, place the tip of the receiver wand into the ring. A beeping tone from the receiver indicates the clamp’s low-frequency is operational. Next, select high-frequency on your receiver. Keeping the sensitivity knob set at 2, place the tip of the receiver wand into the ring. A beeping tone from the receiver indicates the clamp’s high-frequency is operational.
2. Position the clamp around the target conductor below the electrical ground making sure the jaws on the signal clamp meet squarely and are fully closed. The better the jaws meet; the more signal will be applied to the target conductor. To ensure that the transmitter signal reaches the receiver, the path between the point where the signal is applied and the point where it is received must be complete. If you suspect a break in this path, look for disconnected leads, circuit breakers, and open switches. Both ends of the conductor should be grounded. If clamping around a gas pipe at a meter (for example), place the clamp below the insulator and attach a ground lead between the clamp and insulator. A week signal may be due to a poorly grounded conductor. Power lines and telephone sheaths are typically grounded on both sides of the signal clamp position.
3. Plug the signal clamp into the jack on the Pipehorn transmitter. Turn the transmitter on. Signal should now be applied to the target conductor.
4. Start with the receiver set for low-frequency (800-HL model). Begin tracing the signal. The clamp also works in the high-frequency mode.

SIGNAL CLAMP FOR INDIVIDUAL CABLE IDENTIFICATION

1. Set up the signal clamp around the target conductor as described above.
2. At the next vault or access point, place the tip of the Pipehorn receiver on each cable listening for the strongest signal. NOTE: This method will be successful only when there is no common or cross-bonding of the cables between the clamp (where the signal is applied) and the receiver (where the signal is detected).
