Abstract
There is described a device, such as a wireholder, for measuring a load of an elongate member, such as a power line. The device includes a body, a load-bearing member, and a first sensor operable to measure a load applied to the load-bearing member in a first direction, for example a direction of sensitivity defined by the first sensor. The load-bearing member is movably coupled to the body such that the load-bearing member is displaced from a reference position as a function of a load applied to the load-bearing member in a second direction, such as a direction normal to the first direction. The device may further include a second sensor for measuring a displacement of the load-bearing member.
Claims19
A device for measuring a load applied by an elongate member,
- comprising:
- a body;
- a load-bearing member;
- a first sensor operable to measure a load applied to the load-bearing member in a first direction;
- a second sensor operable to measure a displacement of the load-bearing member from a reference position,
- wherein the load-bearing member is movably coupled to the body such that the load-bearing member is displaced from the reference position as a function of a load applied to the load-bearing member in a second direction, and
- wherein the second sensor is operable to measure an angular orientation of the load-bearing member relative to a vertical axis.
A system comprising:
- a device for measuring a load applied by an elongate member, comprising:
- a body;
- a load-bearing member;
- and
- a first sensor operable to measure a load applied to the load-bearing member in a first direction,
- wherein the load-bearing member is rotatably coupled to the body such that the load-bearing member is rotated relative to the body as a function of a load applied to the load-bearing member in a second direction;
- a second sensor operable to measure a rotation of the load-bearing member from the reference position;
- and
- processing equipment configured, based on a reading of a load measured by the first sensor and a reading of a rotation of the load-bearing member measured by the second sensor, to determine a load applied to the load-bearing member in the second direction.
A method of determining a load applied to a wireholder, comprising:
- providing a wireholder comprising:
- a body;
- and
- a load-bearing member movably coupled to the body such that the load-bearing member is displaced from a reference position as a function of a load applied to the load-bearing member in a first direction;
- positioning an elongate member on the load-bearing member so as to apply a load on the load-bearing member;
- and
- measuring the load applied to the load-bearing member in the first direction, wherein measuring the load comprises:
- measuring, relative to the reference position, a displacement of the load-bearing member in response to the load;
- and
- measuring, based on the displacement, the load applied to the load-bearing member in the first direction.
A device for measuring a load applied by an elongate member, comprising:
- a body;
- a load-bearing member;
- a first sensor operable to measure a load applied to the load-bearing member in a first direction;
- and
- a transmitter communicatively coupled to the first sensor and configured to transmit a reading of a load measured by the first sensor,
- wherein the load-bearing member is movably coupled to the body such that the load-bearing member is displaced from a reference position as a function of a load applied to the load-bearing member in a second direction, and
- wherein the transmitter is further communicatively coupled to a second sensor and further configured to transmit a reading of a displacement of the load-bearing member from the reference position measured by the second sensor.
