KCW series Weldable Waterproof Strain Gages


The KCW series foil strain gages are weldable gages, which do not require any coating treatment for use under high pressure or under water.
The G10 type endures a water pressure of approximately 10 MPa.



• Progress and developing velocity of the crack are electrically obtained.
• Applicable to both flat and curved surfaces.
• Resistance change vs crack length is virtually linear.
• Dedicated adapter enables use of a conventional strain amplifier.
• Extremely simple and convenient compared with the conventional optical method.
• Allows 2 trigger wires each in front of and behind the grid (KV-5C) to be used for automation of measurement.
