Abstract:
1. A system for monitoring a force exerted on a pipe section, the system comprising: a light emitting diode supported within the pipe section to emit light within the pipe section; an optical sensing device supported within the pipe section and spaced apart from the light emitting diode; an optical mask disposed within the pipe section between the light emitting diode and the optical sensing device, wherein the optical mask comprises an orifice to allow a light beam to pass through the mask, and wherein the mask blocks any remaining light from the light emitting diode; wherein the optical sensing device transmits a detection signal indicative of the position of the light beam on a surface of the optical sensing device; and a processor for receiving the detection signal and processing the detection signal to determine the force exerted on the pipe section.
