n: a strained sensing element installed on the strained joint of the double-barrelled elevator

n: A wireline tool used to determine the free point on a stuck string. The free-point indicator operates by detecting stretch in the tubular when tension is applied at surface. If stretch is not detected, the string must be stuck above the tool;if stretch i

a tool with strain gauges that is run on wireline and moved along the stuck pipe with successive pipe pulls until the stuck point is located.

a device based on strain gauge technology that helps measure the surface weight of coiled tubing.

n: an instrument used to measure minute distortions caused by stress forces in mechanical components.

n: A kind of gauge used to measure the microstrain because of the force applied on the element.


a electronic “Wheatstone-type bridge” element than may form the measurement basis for a load cell or other strain measurement application. The device measures changes in electrical resistance produced by changes in load.
