Torque Measurements in the Paper Mill Industry

Torque bridges using transducer-class strain gauges 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 gauges 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 Systems

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. However, since the robot’s motions and cycles are programmable, it is possible to specify a “check cycle” at regular intervals. As part of their programming, weld robots periodically move the weld tips into a tip dresser that grinds them into the optimum shape. Once this process is complete, the weld robot can be instructed to move to a check station, where it 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.

Motion Sensors in Municipal Wastewater

Managers and operators of municipal wastewater treatment plants appreciate moving-cavity pumps for handling sewage because they have no valves and can handle most of the solids appearing in sewage. The Mark II is, by definition, a rotary-speed-sensor. Because almost all electric motors are speed-sensitive to torque, the Mark II can also operate effectively as a torque sensor. As rags, paper and debris build up around the shaft, slowing the flow of liquid, the friction between the shaft and the rubber stator increases. This increased load causes a reduction in pump shaft speed. The Mark II can detect a speed change as small as 1 rpm and, with a circuit provided for alarm/shutdown, can power down the pump long before stator burnout.
