Description

This type of system is used in applications where there are more than on set of tongs being used with different handle lengths. A 6 inch fluid-filled gauge reads directly in pounds of line pull which works in conjunction with a load cell that is connected directly to the tong handle.As each joint is made up, line pull is converted to a hydraulic pressure signal within the cylinder and sent to the gauge via a rubber hose, the gauge displays this signal as pounds of line pull. To determine the actual torque being applied you multiply the gauge reading by the tong handle length in feet. The gauge comes complete with a target pointer that the driller sets to a corresponding torque requirement.
