Induction Clamp

An optional signal clamp can be connected to the transmitter and clamped around a cable or pipe to apply the transmitter signal. This method of applying the transmitter signal is particularly useful on insulated live wires and removes the need to disconnect the supply to the cable. Clamps are available up to 8.5” / 215mm in diameter.​

When to use Induction clamps​:

• Clamps can be used where:​
  • Several cables or pipes run in close proximity to each other.​
  • A cable or pipe is accessible at an inspection hole or manhole.​

Connecting an Induction clamp​:

1. Put the clamp connector into the accessory socket on the front of the RD7200 locator.​
2. Place the clamp around the pipe or cable and switch the locatoron.​
3. Set the frequency to the same as that on the transmitter.​
4. Put the clamp around each cable in turn and note the bar graph response. Compare the strength of response from each cable. The cable with a substantially stronger response than the others will be the cable to which the transmitter signal has been applied.​
