A chain wear system for monitoring an amount of wear of a chain operating on a plurality of sprockets may include a chain monitoring device configured for determining a length of the chain passing by a point in an amount of time, a sprocket monitoring device configured for determining the amount of sprocket rotation of at least one of the plurality of sprockets in the amount of time, and a processing system in signal communication with the chain monitoring device and the sprocket monitoring device. The processing system may be configured for calculating the amount of wear based on the length of the chain and the amount of sprocket rotation.

Chain wear sensor

A coiled tubing injector system includes a traction system for advancing coiled tubing through the injector and into or out of a well. The traction system includes a plurality of carriers () and gripper shoes () configured to repeatedly propagate through the injector along guides (). The traction system also includes a position monitor () for monitoring the lateral position of the carrier, gripper shoe, or portion thereof as the carrier and gripper shoe propagates along the coiled tubing path.
