Abstract
Aspects of the present disclosure relate to a multiple range load cell capable of automatically switching measuring range and method for operating the multiple range load cell.
Claims20
A load cell assembly, comprising:
- a load cell body configured to perform torque measurement in two or more torque ranges;
- and
- a controller connected to the load cell body for data communication, wherein the controller is configured to acquire information of an active torque range of the load cell body, and send command to the load cell body to switch the active torque range to another torque range of the two or more torque ranges.
A method, comprising:
- measuring a torque using a multiple range load cell including a controller connected to a load cell body having multiple ranges, wherein the multiple range load cell is configured to measure the torque in an active range;
- receiving a change in a target torque;
- and
- switching the active range to another range of the multiple ranges of the load cell body upon receiving the change in the target torque using the controller.

A tubular make up tool, comprising:
- a tong assembly;
- a load cell body attached to the tong assembly and configured to measure torque applied by the tong assembly in a selected range of two or more torque ranges;
- and
- a controller connected to the load cell body for data communication, wherein the controller is configured to acquire information of the selected torque range of the load cell body, and send command to the load cell body to select another range of the two more torque ranges.
