Torque Measurements in the Paper Mill Industry

Torque bridges using transducer-class strain gages are installed on the inner diameter of specialized tools for monitoring levels during the pulping process in a paper mill. The installation area is hermetically sealed for environmental protection including moisture. These level indicators provide production efficiency during manufacturing.

Cement Shrinkage Measurements

Encapsulated strain gages are applied to a hollow sleeve with the capacity to survive in a high PSI alkaline water mix for recording data as the cement dries.

Weld Robot Check System

One of the major contributors to the quality of a spot weld is clamping force. This clamping force is typically audited by a technician, making periodic measurements of the weld force using a hand held instrument. Since the robot’s motions and cycles are programmable, it is possible to program a “check cycle” into the welder’s program at regular intervals during a typical day, weld robots are programmed to move the weld tips into a tip dresser that grinds the tips into the optimum shape. Once this process is complete, the weld robot then is instructed to move to the Weld Robot Check Station. Here, the weld robot momentarily clamps down on a sensor that measures clamping force. The Weld Robot Check Station has memory on board that can hold thousands of measurements.
