The invention relates to a load detection unit having a spring-elastic load carrier assembly for receiving the load (10) and a sensor (3) for the deformation of the load carrier assembly, which occurs under the load (10) that is to be detected, wherein a deformation transmission unit (6) is operatively arranged between the load carrier assembly and the sensor (3). A method, in which additionally a deformation transmission unit is used, is thus provided, which during operation picks up the deformation of the load carrier assembly and transmits it to the sensor as a changed force/path load.

A cable puller includes a frame, a capstan mounted on the frame around which a pulling rope is wrapped, and a sensor configured to measure the distance the pulling rope travels relative to the frame. The sensor may be a Hall effect sensor and/or an optical sensor.

There is provided a measuring device (dial gauge) capable of performing measurement with a desired measuring force regardless of the posture of the measuring device. A dial gauge in an exemplary embodiment of the present invention includes a measuring force adjustment unit provided to a body case and capable of moving and being positioned and fixed in a direction substantially parallel to a moving direction of a spindle. A biasing means has one end directly or indirectly engaged with the spindle and the other end directly or indirectly engaged with the measuring force adjustment unit, and biases the spindle toward a tip end. The measuring force adjustment unit includes an external thread portion and a connection supporting member having one end screwed with the external thread portion and the other end coupled to the biasing means. The connection supporting member is screw-fed by rotationally operating the external thread portion in such a manner that a position of the connection supporting member is changed and fixed.

The present invention is related to a method for detecting and/or measuring atmospheric accretion on a suspended electrical cable span (2) of overhead power lines, said suspended electrical cable span (2) having a sag (D) and a local tension (H), and being submitted to wind pressure (w.sub.wind), comprising the steps of independently: measuring said sag (D), and optionally measuring the wind pressure (w.sub.wind), over a first time range, measuring the local tension (H) over a second time range,
the results of both steps being complemented and/or combined, so that to allow atmospheric accretion detection and/or measurement.

The present disclosure includes devices and method for measuring tension in a test object. An example device includes a probe configured to exert a force upon a test object at a particular location, a sensor that detects the force that the probe exerts upon the test object, and a switch that signals the sensor indicating the test object has been displaced a particular distance and/or angle, such that the sensor measures the force at a time when the test object has been displaced the particular distance and/or angle.

A gauge device according to some embodiments of the disclosure is configured to measure tension on a pulling rope during a cable pull. The gauge device according to some embodiments of the disclosure includes a frame, a housing carried by the frame, a roller rotatably carried by the housing, a sensor on the frame beneath the housing, and at least one additional roller rotatably attached to the frame. The housing is configured to translate linearly relative to the frame, such that when the housing moves relative to the frame, the housing is configured to engage with the sensor to activate the sensor.
