Abstract
A method and apparatus for measuring tension imposed on a cable by a pull line in a conduit includes a tension meter coupled between the cable and the pull line. The meter includes a load cell connected to an electronic circuit to operate an audio transmitter in one embodiment, or to generate an electromagnetic field parallel to the conduit according to a second embodiment. The electromagnetic field induces a tension signal in a metallic conductor extending parallel to the conduit. The audio or electrical signal is transmitted for detection and for operating a display. An operator uses the display to control tension in the pull line.
