The AM5K Wireline Measuring Device from BenchMark Wireline is a compact and lightweight device for measuring both wireline depth and tension. It will work on both open and cased hole wireline units which allows standardization on a measuring head for all types of operations. It is designed to be mounted to the spooling arm of a wireline unit.

The AM5K uses dual spring-loaded measuring wheels to measure the amount of wireline moving in or out of the borehole. The measuring wheels are coupled to optical encoders that transmit electrical signals to the hoistman’s panel and/or logging computer.

The AM5K uses an electronic load axle to measure wireline tension. Three wheels are used to create a force on the load axle. The wheel mounted on the load axle is offset from the two guide wheels. This creates a slight bend in the cable.

As wireline tension increases the bending of the cable creates a corresponding force on the strain-gauged load axle. This electronic signal which represents line wireline tension is transmitted to the hoistman’s panel and/or logging computer.
