Title: AUTOMATED LOAD CELL IDENTIFICATION
Abstract:
Aspects of the present relate to automated load cell identification. A method is provided. The method generally includes sending, from a load cell to a remote processing system, identification information associated with the load cell; and determining whether the load cell is valid for use during makeup of a threaded connection of a first threaded tubular to a second threaded tubular based on the identification information associated with the load cell. The load cell identification information may include a measurement range of torque values supported by the load cell. The method can include comparing the measurement range of torque values to a job defined range of torque values associated with the makeup of the threaded connection; and determining that the load cell is valid for use based on the comparison. The identification information can be used to detect the load cell type, range, and calibration data before tubular makeup to ensure data quality and safety at work.
