Transmitter Signal Clamps

Signal Clamps provides a precise way to apply a locating signal. It is generally used when it is not possible or convenient to access the conductor to make a direct connection but there is sufficient room to place the clamp around the cable or pipe, or when it is not safe to make a direct connection because the target cable is carrying electricity. 

Signal Clampsare specialized inductive devices, sometimes known as a toroid or coupler. All clamps are optimized to work at specific frequencies. In most cases clamps are designed to be used at frequencies generally between 8kHz and 83.1kHz. 

  • Range of clamps from 2” to 18” 
  • Apply a transmitter signal to live cables 
  • Apply locate signals on lines in a range of situations
