Strain Sensors Measure Quality on Resistance Welding Machines

 

 

March 2, 2006, Depew, NY, USA - New Series JM240 ICP Ground Isolated Strain Sensors from the Force/Torque Division of PCB Piezotronics, Inc. (PCB) use piezoelectric sensing elements to indirectly measure dynamic and quasi-static stress forces on resistance welding machinery structures. ICP Strain Sensors feature sensitivity stability, repeatability, high resolution, and extremely long life. Mounted on a C-frame or actuator with a single screw keeps the sensor out of the current flow and high electrical noise environments do not affect the ground-isolated design.

 

Weld quality is directly affected by electrode force, and -- in typical applications -- the sensor is used to verify that the clamping force has reached a desired minimum value before applying weld current. The strain signal may also trigger weld current, which cuts cycle time by applying weld current immediately upon reaching the desired force, and avoids electrode damage due to premature current application. Sensor data may be used to trend electrode tip wear, capture process deviations, and document the process to ensure delivery of zero defect product components.

 

Other applications include stamping, pressing, punching, crimping, forming, plastic injection molding, and automated assembly operations. Series JM240 ICP Strain Sensors are easy to install, and can be powered by any ICP sensor signal conditioner.
