Design
of the RLT is deceptively simple. It employs three
precision engineered roller bearing sheaves mounted
in a rigid frame. The line to be monitored is threaded
under the outer sheaves and over the center, pivoted
sheave which rests against a Dillon electronic load
cell. As tension increases, the center sheave compresses
against the load cell. This force is transmitted as
an electrical signal to the indicator where it is
displayed as a direct reading of line tension. |
