Device provides consistent proximity sensing in automated resistance welding operations

May 4, 2004

Canfield Connector's EOS differential pressure switch provides consistent, repeatable proximity sensing in automated resistance welding operations. The EOS works in the pressure line between the actuator and the valve and is not affected by changes in stroke length, differences in metal thickness, weld tip erosion, or system pressure drops.

The switch does not use magnetism or inductive sensing and is unaffected by weld fields, eliminating the need for constant calibration. It can be mounted at or away from the cylinder and will not trip in low-pressure situations.
